The Project Control Meeting Agenda for Monday March 22, 1999 will be:
CANCELLED DUE TO HOLIDAY
Last week, the last beam-tube module bakeout at
Hanford was signed off. This week, an even
longer term project came to fruition when our
drinking water system was certified as complete!
Facilities:
-----------
O. Matherny
Water System modification: The water system was approved by the state Health Department.
New staging Building: The contractor is 70% complete with the
building. Interior insulation, wall
panels, electrical and plumbing work are on going.
Compressors: No change, the contractors are pointing fingers at
each other. Will take a little more
time to sort it out.
Water Supply:
The well pump is repaired. It only lasted 23 month and usually they
last 20 years. Unfortunately it
only had one year guarantee.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #32 consisting of misc. Conflat vacuum fittings
(Matt Smith),
HAM leg screws (type 1), HAM leg screws (type 2) and HAM safety
pins (Corey Gray) was
released on 5-25-99. This particular load was the "dirtiest"
with regard to hydrocarbon sum
masses (high E-10 torr*L/sec) of any load yet released.
LHO Vacuum Bake Oven A load #33 consisting of IOO small optics (Haisheng
Rong) s/ns
MCCM2K01-1, MCFM08-1 and MMT22K-1 is vacuum baking and will be done
on Friday
5-28-99.
LHO Vacuum Bake Oven A load #34 is scheduled to consist of two large optics.
Reminder- If you want something vacuum
baked here at LHO, you are required to provide Bartie
with a traveler form having all applicable
fields filled in prior to baking.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
BSC7 work:
After determining that a seal on two different
Bellows were "leakers", we conducted a Gasket
Replacement utilizing the Jib Cranes--thus, not
forcing us to remove the dome and/or other
components. This job worked rather well.
However, we did have an incident. A steel
plate/bracket (roughly 30-40 lbs fell about 12-15
feet nearly hitting a certain visitor from MIT. We
had a meeting with all of those involved, who
were still on site, and with Otto M. We are going to
require that a hard hat be worn whenever work
is being done above you--unless it is specifically
stated otherwise. We are also going to
establish "Task Leaders" who will be responsible for any
given activities going on.
##############################################################
FJR clarifications:
1. Hard hats were always required outside the
portable clean rooms when work was ongoing
above, but an exemption was made for work within
the clean room because of a judgement that
there were clean room jobs that were not feasible
in a hard hat and these occurred under
circumstances where heavy objects could fall.
Since this has proven false, we are tightening up the
procedure.
2. No work has been permitted without a task leader,
whose name is given on the work permit.
The newly established rule is that the names
of task leaders for each permit will be read at the work
permit meeting to ensure that new members joining
the team know who directs them and so that
task leaders do not forget their responsibility.
Currently, the dome is off BSC7 and the Stack
is being assembled.
###############################################################
BSC3 work:
Scissors Tables were installed. The mounting clamps have not been installed.
Other activities/notes:
Hardware is being staged out at both mid stations.
Doors were removed from HAM8 for Optics installation.
Optics:
---------------------
(D. Cook & B. Weaver)
The week of June 7th we are very likely to be
in the "Laser Hazard" condition at Hanford. Please
be prepared. Please have your "baseline" eye
exams completed prior to coming to Hanford if you
are planning on working in the LVEA. You may
have other laser safety issues to get current on as
well.
The FMy for the 2k interferometer has been balanced once again and is
ready to go into the
vacuum bake oven Friday. Hopefully the ITMy-2k will be ready for the
same vacuum load as well.
The new LOS gluing fixtures worked well. The process provides much
stronger bonds than before,
but with the fixtures and optics preheated to 100*C, handling becomes
more difficult. Time
becomes more critical in order to maintain this temperature while gluing
and placing the magnets into
the fixture. After an hour of cure time the devices that locate the
magnet assemblies into the fixture
are removed, the oven is switched off and the entire works is allowed
to cool.
The Recycling Mirror, y-arm 2k IFO will have its OSEMs replaced and
the optic will be realigned
hopefully the 1st week of June. The ITM and FMy will then follow on
in the second week. The
replacement lateral telescope needed for this installation arrived
here from PLX in one piece. (the
prior one was not so lucky). If all goes well the Core optics will
now have a steady flow of
processing and installation.
Computing Systems:
------------------
(C. Patton)
Tried to install new patches for Solaris 2.6 and for Workshop 5.0 compilers,
discovered that there
is not enough disk space left to install the patches. Ordered
another 18GB external disk.
Rebooted the server to clear out old spool files, auto-mount the new
email accounts to the server,
and removed a broken scsi tape drive.
Temporarily put one of the LDAS Sun workstations on the GC network along
with it's external 18
GB disk so that LDAS can use ftp to start transferring software to
LHO.
Electronics & Electrical Systems:
---------------------------------
(R. McCarthy)
All of the GPS antenna cables have been installed in the Mid and End
Stations. We need 4 more
connectors to complete the terminations. We have the Left mid
station GPS clocks running and
locked. The other stations will be hooked up as the timing
cards arrive.
The FM antenna and cable have been installed at the corner station and
routed to the MSR for
hookup to 4 receivers.
Josh is assembling Kapton cables in the Vacuum Prep lab for installation into the BSC on 5/27/99.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
As reported in the weekly (5/18/99) report from Gary Sanders the bake
of X2 module is complete.
We are removing the last of the equipment (RGA, turbo and cryopumps)
and packaging for
shipment to Livingston. We have completed the Neon test of the 44"
gate valves on X2 and the
results are that neither valve leaks. This test verifies that the gate
valves still function properly after
the bake. We are working to be able to ship a large amount of the equipment
next week to help
facilitate setup in Livingston.
Beam tube bakeout: An inspection of the X-1 module was completed on 5-24-99. We found 7 discrepancies in the insulation and one missing TC. A second LIGO acceptance walk down inspection has been scheduled for 5-28-99. This inspection will also include the Y-1 module. Custom Concrete Cutters Inc. has completed the coring of all the holes required in the BTE along the X and Y arms. A total of 54 ea. 6" holes and 29 ea. 4" holes were cored. (Cecil Franklin, Kerry Stiff)
Optics: Completed the cleaning and vacuum bake of 12 ISC viewports, and installed 6 on the vacuum system in the vertex. Used the new jumbo ultrasonic cleaner to process seven large boxes of SOS hardware from U of F, which has been cleaned and will go into the vacuum bake oven along with the LOS for MMT-3 next load. Identified by type, and placed in clean storage the remaining 7 LOS structures. Began installation of grout and mounting plates for three ISC piers in the vertex. Located some stock SS baskets which may be stacked containing small parts. These are suitable for use in the bake oven, and will permit us batch the numerous small items with other bakes more efficiently. Ordered 4 additional material handling carts from LISTA, for transfer of clean components, as well as 4 wall units for the shop. The shop, by the way, is now being well used for detector, as well as facilities support. Completed plumbing the shop with air lines. (Jonathan Kern)
Electrical Engineering: The Livingston CDS web site is now under construction. Juilien is using some of the work already done by the folks in Hanford and editing it for our own use. She is also preparing an inventory of all the components here in Livingston (installed and in stores). Some of the information included at the web site is not for public viewing so she is including password protection to prevent unauthorized access. A computer desk for the Mass Storage Room is on order. Three split back crates were received from Hanford. Two of them received some damage during shipping. These two crates will be photographed and included in this week's photos. I will be sending them to Rolf and he is going to decide what to do with them. We are still waiting for the 220's (digital output boards). Xycom had some QC problems. Jay Heefner is looking into it. We need one for the suspension test stand. Final testing of the SOS controller is ongoing. The controller is the other piece required to finish the suspension test stand control rack. Cable tray installation is ongoing. We have received the two large shipments of material. The tray supports (16) are on order from Southern. The first four should arrive on Tuesday, June 1. Installation in the corner station is 70% complete. (Rus Wooley, Juilien Svoboda)
Weather Station:Previously identified problem with weather data
on medm screen was found to be part hardware part software. Software component
fixed. Hardware component being checked. High error rate is appearing at
input to VME crate.We are in process of diagnosing source of hardware problem.
Error checking within software is 80 % complete. Waiting for 162 that can
be dedicated to weather station.
GRASP - Process of putting data in from an ADC to the linux
machine is in place and successfully tested. A 200Hz signal was injected,
seen with dataviewer, put into files using jdclient, ported over the lynux
computer and viewed with animateF; the frequency and time domain both looked
reasonable. Work continues to get other grasp functions to read ligo frame
data. Development version and newest release of Grasp have been installed.
End to End model - Pulled over latest end to end software, and
newest PSL model. Went thru ISS with Biplab. (Anthony Rizzi)
Interferometer sense/control (Zucker)
-------------------------------------
Site delivery & integration:
No major ISC shipments are planned/required over the next few weeks.
Prealignment of ISCT9 and ISCT10 optical subassemblies is now beginning
at MIT; these will probably start to ship mid-June (tables and enclosures
are already on site).
Initial alignment (MZ for K. Mason & M. MacInnis)
-------------------------------------------------
Hugh Radkins of LHO has kindly offered to survey initial alignment
monuments for us at LLO starting on 6/14, using the precision
GPS-calibrated beam tube supports as primary references. We will
later
do an axial beam-tube sighting on one or both arms (as permitted by
the
LLO tube bakeout schedule) to verify closure.
KM and MM are scheduled at LHO from 6/10 through 6/25 to support
installation of FMy and ITMy. MZ will arrive 6/26 to cover the
tail
end. LHO travel in mid-July is probable to cover BS and (possibly)
ITMx and FMx, but are not yet definite.
Our PLX lateral transfer periscope arrived at LHO in good shape.
ISC implementation (Nergis Mavalvala)
--------------------------------------
More progress was made on measuring the excess RF AM noise. The 22
Hz and 154 Hz resonances were identified to be the flop modes of an
anodized Al plate we were using as a beam dump. This has been replaced
with a conical beam dump. This reduced the noise at 100 Hz to about
1
dB above shot noise (for 4 mW of power or ~2 mA of current).
We are now attempting to make the measurement at higher power using
an LSC length PD which can handle up to 100 mA of current. The RFAM
PD
from IOT7 was borrowed for the measurement but had a problem with the
bias enabling. It is being repaired at CDS-CIT. A broadband version
of
the LSC PD is currently being
set up.
ISC implementation (Peter Fritschel)
------------------------------------
o We've been looking for low-scatter mirrors to use as steering
mirrors in front of the LSC photodetectors. REO-coated super-mirrors
would of course do the job, but we're also evaluating various
off-the-shelf mirrors to see if any of them are smooth enough -
so far none are.
o Some progress with the E2E-based lock acquisition model of
a 2km long cavity. I've got a configuration which locks, and
I'm now beginning to explore the relationships between servo
gain, servo bandwidth, actuator and sensor limits, relative
mirror velocities, etc.
ISC supervisory controls & GDS/DAQ interface (Ed Daw)
------------------------------------------------------------
For the last fortnight I have been installing and testing ddcu
code at Hanford and starting to integrate it with the gds diagnostic
engine. Numerous handshaking problems have been found and solved, though
some still exist, particularly with interfacing the front end servos
to the data collection unit. This last problem has prevented the test
I really wanted to do where test signals would be generated on Daniels
excitation engine and viewed at the output of the Pentek ADC. Some
other
problems that have been solved are 1) The epics state code for controlling
slow servo controls has been re-compiled for a motorola mv162-333
running as a slave CPU in the data collection unit crate. 2) The
ddcu code now updates the test point validity words and copies test
point data between the ISC supervisory reflective memory and the
data acquisition loop 3) The medm screens constructed by Peter and
Nergis for the ASC servo slow controls are installed and working as
part of Hanford Channel access. Front end reflective memory for
the servo control parameters now updates correctly when changes are
made
to these screens in medm. 4) The vmicWrite routine I have for DMA
transfers using the VMIC5588DMA reflective memory module has been
updated to perform both VME writes and VME reads.

Lasers and Optics -- J. Camp
(1.2.1.1.2, 1.2.1.1.3, 1.2.1.1.4,1.2.1.1.5)
--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- The LLO PSL reference cavity and supporting hardware, such as the
vibration isolation stack and vacuum chamber, has been assembled.
The
form fit heater jackets; temperature sensors and thermal insulation
have
been fitted to the reference cavity vacuum chamber. Currently
the whole
system is being roughed down with a turbo pump with the pressure sitting
at
approximately 1.5E-6 torr. Switching over to the ion pump will
occur soon.
- The intra-MOPA EOM is currently being installed.
- Scale-able font versions of the PSL operator screens have been created.
Enhancements include the implementation of a crude on-line help screen,
outlining what the various buttons do, displays mean ... etc.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
Small optics gluing
We glued wire standoffs and guide rods to three optics using the
old fixtures. Then we glued dumbell magnet combinations to these optics
using the new fixtures. All of the remaining IOO optics are
currently baking.
Overall, the new fixtures are MUCH, MUCH better
than the old fixtures.
The time it takes to glue six magnets/dumbells
(with new high T cure) is ~
3 hours. If the magnets/dumbells are cured and
available, we can now do 3
small optics in one day!! The slow process
is still the gluing of the
standoffs and the balancing. The bonds seem to
be exceedingly strong after
the cure (do not come off after hour long soaks
in liquinox at 70C).
RFAM related measurement
Nergis, David Shoemaker, and Dave Reitze continued
to hunt for the cause
of the excess demodulated RFAM discovered by
Peter. The cause has been
traced to parasitic interferometers in the PSL/IOO
beam path due to highly
backscattering beam blocks. Tests are underway
to select the low
backscatter, high power handling beam blocks.
There is considerable level of signal at the modulation frequency when
the
second polarizer (the polarizer sitting in front of a photodetector)
is
absent. New Focus says there should not be any polarizing effect in
the
EOM (the surface is perpendicular to the beam path and the coating
should
not have a polarizing effect). Sany is investigating this
effect.
LLO 4k
The suspensions have been received at LLO. Other than that, no
significant activity to report.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
We have surveyed the four coated SPETMs, these are End Test Masses coated
by General Optics. At first glance, they are well matched, only
20m
difference in the ROC of numbers 03 and 04. However, the absolute
Radius
of curvature is running roughly 800 meters longer than our goal of
7400,
and 580 meters longer than the outside tolerance. At this radius
of
curvature our uncertainty is fairly small ~130meters.
The direction of the problem (flatter) is unexpected, we expect our
coatings to shorten the radius slightly, perhaps 100-200 meters at
this
radius. We are looking into possible causes and courses of action.
# DHS we will need to evaluate the impact on interferometer
performance as
well.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
Bonding Issues: Within less than 2 weeks, we have successfully bonded
3
Small Optics and 2 COC's. The SOC's have been balanced and are undergoing
a
vacuum bake. The Folding Mirror and the ITM are in the balancing stage.
The new bonding process worked good, the new fixtures worked good and
we
are discussing some fine tunning to make them more efficient. The whole
process has been shortened quite a bit. We
are "on line" again!!
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE
Awaiting completion by SORL of the parabolic mirrors. Primary
and
secondary alignment mirrors have been received. Fixtures to hold the
alignment mirrors for the initial PO telescope alignment are being
fabricated. Ken M will resume cleaning up the production drawing package
next week.
ETM TELESCOPE
The lens housing of the first article is being reworked to accomodate
a
slightly oversize production lens. The mounting assembly for
the steering
mirror is being reworked. Assembly tools for inserting the lenses are
being
fabricated. Ken M. is completing the production drawing package for
the ETM
telescope.
PO MIRRORS
Ken M. has completed the production drawing package for the PO mirrors.
CAVITY BEAM DUMP
Purchase orders have been placed for all of the beam dump structures
in
BSC1, BSC2, BSC3, BSC4, BSC7, and BSC8 of LHO and LLO. The glass for
the
plate beam dumps is being AR coated. Craig C. is completing the assembly
drawings for the chambers.
VACUUM WINDOW
Awaiting delivery from Varian of the re-made con-flat o-ring groove
parts.
COS IR ALIGNMENT BEAM
Awaiting delivery of the IR laser source. The surveillance camera,
IR
filters, and TV monitor for viewing the projected alignment beams have
been
received. C-mount lens adapter spacers and filter holders are on order,
and
the IR filters need to be sent out for edging.
ARM CAVITY BAFFLE
Paul K. has resumed detailing of the arm cavity baffles.

Seismic Design (Mike Fine)
--------------------------------------
1. Electronics Rack
The multiplexer was installed last week and the connections to the
top plate
were completed this week. The internal wiring (side panel to
MUX) was started
last week and will be completed next week. The rack computer
has been
configured for 3 BSC control and will be installed after the pneumatics
and wiring is complete. Hytec is still on target to complete
the rack
assembly by the end of next week and will proceed with rack debug at
that time
2. Fine X-Stage:
The Fine X-Stages were originally scheduled to be completed in Mid-May.
Delays have pushed them to the end of May, however it does not appear
that
LHO will receive the first assemblies by the end of next week.
Hand
Precision is currently finishing the April and May delivery of the
Scissors
Tables. They will begin Fine stages once a CNC machine becomes
free.
As it is now, Hytec will receive the first assemblies beginning the
first
week of June and will assemble the unit to check proper fit. The remaining
three units will be shipped to LHO directly by Hand Precision.
3. Scissors Tables
Hytec has completed assembling 16 HAM scissors tables and is planning
to
ship all 16 to LHO on Friday. This will complete the HAM scissors table
assemblies for both facilities. They will be receiving 16 BSC scissors
tables
from Hand Precision the beginning of the following week, and at that
time
will begin assembling the next BSC scissors tables for LLO. They
would like
to complete and ship as many of scissors tables as possible before
the June
11th shipment to LLO.
4. Near-Term SEI Hardware Delivery Schedule:
3 BSC Downtubes (Livingston) 6/2
6 BSC support tubes (Livingston) 6/2
3 sets of BSC legs (Livingston) 6/2

Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. Report from Mark:
We got the folding mirror in the oven at 3 pm, Wed after a few small
irritations:
* We fixed the burr that was blocking one of the plungers.
* We fixed (we thought) one of the bushings, which had slipped.
* We modified the magnet test fixture to include a small brass set
screw
instead of the piece of metal that formerly held the probe with its
sweet
spot under the magnet (but had been lost).
* We ultrasonically cleaned the magnet test fixture and used it to
select
a number of matched sets from a supply of magnet/standoff assemblies
which had been made up but as far as we know not been matched.
* We ended up deciding not to bother with the springs for holding the
side plungers. The glue sets more or less instantaneously so there
is
little need for them. Moreover there is also some danger of bumping
the
plunger and breaking the joint while trying to insert the springs without
burning oneself.
* The bushing we thought we had fixed came loose again (apparently
from
the heat) and subsided onto the face of the optic. Since this is the
folding mirror and the AR side is non-critical we decided to leave
it
there during curing. Before we do the ITM, Doug will fit set screws
to
the all the bushings.

---------------------------------------------------------
Global Diagnostics System
(Daniel Sigg, John Zweizig)
This week we have continued to develop user classes for use with root-based
diagnostics. These include multi-channel time display (strip chart)
primitives and further development of the trigger API.
Finished the NDS interface to read channel data. Started to integrate
the
DMT library to read data from the NDS into the diagnostics test tool.
Installed the test point manager in a crate/CPU into the mass storage room.
Installed part of the excitation engine (digital waveforms) in the mass
storage room.
A successful test of generating waveforms on the excitation engine,
writing them into reflective memory through the test point interface,
reading them out through the network data server and displaying
them with the data viewer was conducted this week.
This week we have continued to develop utility functions and classes
for
use in monitors, especially under the root environment. Also have
entered extensive discussions with representatives of the LDAS group
and
of CACR on the representation of triggers to be ingested into the database.
Updated the save/restore function of the diagnostics test tool to the
most
recent standard of the LIGO lightweight data format. Wrote a few utility
programs to store data from the network data server in XML format,
to
print a directory of a diagnostics XML file and to convert LIGFO LW
data objects into simple ASCII or binary format.
Physics Environmental Monitor(Matt Smith, David Shoemaker & Alex
Marin)
-----------------------------------------------------------------------
1.The delivery schedule is posted at :
http://web.mit.edu/marin/www/PEM_Delivery.html
2. Accelerometer positions and locations are posted
at
http://web.mit.edu/marin/www/Accel_Cable.html
Started to install the PEM stay clear zone railings
and came into a
material
misfit. The vendor had welded the wrong base support to the floor
plate so
that
the railing does not fit. The vendor is looking into the
problem. I
currently
ordered a smaller diameter pipe to use as a "sleeve"
between the two.
This
could be a permanent fix but I would prefer to replace the floor
plate
with the
correct part once the vendor replaces the incorrect ones.
Robert Schofield brought to Matt attention
that the magnetometer
holders
supplied by GMW do not securely hold the magnetometers.
After talking
to the
vendor, they said that the holders probably weren't built correctly.
Via
phone
messages they mentioned two fixes 1) put tape around the
mags or 2)
modify the
holder to allow better holding. They did not mention
replacing them
which is
what it will be pursued.
Matt assembled the temperature/humidity sensors and the
accelerometer
triaxial
blocks onto the PEM Beam Tube plates and they fit
fine. He is
planning on
installing these to the Beam Tube next week.
We are shipping to LA the two RGA adapter tubes that will be installed
into the
BSCs at the end stations as part of the RGA tree. They should
go by Tuesday on
the Hytech truck.
We are planning to install the accelerometers and run cables on the
2K PSL,
HAMS 7,8,9,10, and BSC 8 this week.
Had a problem with installing the PEM interface plate
to the seismic
support
tube on BSC7. The tube is shifted from the pillow blocks
so that at one
end it
extends beyond the edge of the pillow block and at the other
end it is
recessed
into the block by 1/2 inch. We will need to order a 1/2 inch
shim to allow
the
PEM interface plate to be installed.
The muon detector design is almost ready. We
are waiting for some
quotes and
then the design will be circulated to interested parties
for comments,
while
parts will be ordered.

Near Term Installation
======================
- June 3 to June 11: Rich @LLO for PSL installation
- June 7 to June 11: Jay & Dale @LHO for mode cleaner control checkout
Timing System: (Dale)
=============
The first of the new GPS Clock Drivers is stuffed. If all goes well
testing
here should be completed by Friday and we will send it up to Hanford
to be
tested on the system by Dave Barker. The Clock Fanouts will be tested
at
the same time. The ISC Clock Fanout that translates from Differential
ECL
to Differential TTL and fans out to the ISC whitening boards is next
in the
queue for PCB layout.
LSC CDS: (Dale)
=============
The LSC photodiode is out for fab (due next Wednesday). We making 10
boards
initially. All of the mechanical drawings are complete and submitted
to the
machine shop for fabrication of the RF box, mounting plate, retaining
ring
and heat sink. Spent most of a day debugging, fixing and testing a
photodiode that Nergis brought back from Hanford (from IOT7). The Bias
Enable chip was bad. This could be because it connects to the outside
world. The voltages on the cable that controls the diode should be
checked.
I have started the design of the LSC Servo Amplifier that will be used
in
the One-Arm test. I have done some work on the 130 dB notch filter
but this
has gone slow partly because other things in the queue and partly because
all of my simulation time must be in the evenings at home (my own SPICE
program) because I haven't been able to get into CADENCE for some time
due
to licensing problems and access problems. I plan to implement a couple
of
different filter designs to see which works best in the One-Arm test.
# DHS sounds like we should find a solution for CADENCE licensing.
Suspension (Jay)
========================
- Wiring of the LLO 4K COS suspension rack cross connects continues
but has
been
slowed by jobs for the LHO 2K one arm test.
- Testing of the suspension controller for the LLO test stand has been
completed. The controller will be shipped next week.
ASC (jay)
========================
- Rack and system wiring diagrams are ~75% complete. Draft copies of
the
drawings have been sent to members of the ISC group for comments.
- Quad photodiode amplifer boards have been sent to the board house
for fab
and
are due back 6/7. Boxes for the QPD amplifiers have been selected and
ordered.
- The following is a list of the custom boards required for the one
arm
test and
their status:

ASC/LSC (Rolf)
===============
- Performing time tests on loaner Pentium III based VME processor board;
using
iir filter code used in ASC/LSC servos as the benchmark. Initial runs
showed
Pentium III 5 times slower than our present MIPS and 10 times slower
than a
standalone Pentium PC (test run by Kent). Sent my code back to factory
for
them
to test on their system. They got the code to run at rate comparable
to Kent's
PC time by changing a cacheing parameter in vxWorks. I should have
a new board
support package today and will rebuild vxWorks and try again. (Note:
reason we
are looking at a higher performance CPU for LSC is that LSC servos
must update
every 62.5usec, and with our best optimization efforts, we can get
the
necessary
code to run at 50-55usec on our present MIPS boards, which doesn't
leave much
headroom.)
Data Acquisition (Alex)
========================
- Working on updating web based data server to retrieve trend data
(presently
can only retrieve data from last 16 hours of online disc).
- Met with Albert's group. Will begin changeout from VIRGO frame code
to LIGO
frameCpp code for writing data frames.
PSL (Rich)
===========
1. Completed a set of calculations for Lightwave Laser Corp.
to predict
the dynamic range of a new high speed power adjust actuator for the
LIGO 10
watt Laser.
2. Worked on the final tweaks to the frequency stabilization servo
card
such that a final design board can be ordered.
3. Putting together hardware for next weeks trip to LLO to complete
the
installation and begin commissioning.

The first samples of the new Fluorel order were submitted to the air bleed bakeout and sent to R. Weiss for testing. This testing is expected to be concluded right after the Memorial Day holiday. If successful, bakeout of new o-rings could start next week.
LIGO QA requested GNB to submit a plan for replacement of o-rings in six Livingston gate valves based on the requirement to have the work completed by 27 June.
LIGO QA has worked with Walker & Sons and Mike Fine regarding the recovered LIGO parts disposition. In addition, thirty two shims were shipped to Walker for processing. LIGO QA will be at Walker & Sons next week (Thursday) to audit the status of their recovery and to ascertain if additional support from LIGO is needed to assure meeting LIGO delivery schedule needs.
All of the Caltech extraction hardware orders have been completed. The electrical modifications in the 058 area are complete. A draft version of the extraction process is almost complete. The list of Caltech equipment has been provided to Walker & Sons for loan consideration. Final disposition of the Caltech equipment will be considered after LIGO QA visit and discussions with Walker & Sons.
Received LLO operating procedures and plans. Distributed and started
review. Received a few comments against the Project Laser Safety Plan and
the Operations and Environmental Protection Manual. Incorporated the changes
and distributed for final signature approvals.
Ed has cleaned up alfi code and version 3 and version 4 are now built
from the same
code base. Ed started to modifty the code structure to use AutoMake
and AutoConfig to
make it easy to distribute.
Soumya [PSU] visited Caltech, and worked with Hiro and Malik on suspended
mirror
modeling. Malik has written a very simple version of a single suspended
mirror, which
will be used as the simplest mirror model in e2e. These two models
were compared and
it was confirmed that they match very well in the region where Malik's
model is valid.
Soumya will modify the code to include a structural dumping, and Hiro
will provide a
code to convert Soumya's model to e2e time domain model.
Malik and Constantin Brif and others discussed about the formulation of the thermal noise.
Biplab continued working on the PSL subsystem modeling and cleaning
up the optics/field
implemenation.
Hiro started work on implementing a 3D suspended mass model in the e2e
framework.
Hiro worked to improve the modeler_freq and other improvements of adlib
code.
Hiro, Matt and Ed discussed about the dependencies of box files in order
to avoid name
conflicts, and to make it easy to customize.
* (MB) Got IBM's latest version of C++ XML parser [source code!] which
supports Solaris,
installed it on my system.
* (MB) Reviewed documentation on some of the classes used in IBM's XML
parser.
* (MB) Met with Dave and Phil to get information on g++ compiler and
Solaris/Linux platforms.
* (MB) Started building IBM's XML parser library using IBM provided
make
files.
Kent Blackburn:
* (KB) Met with Network Alliance to discuss network file server solutions.
* (KB) Met with Fore to discuss switching technology solutions to use
with
the LDAS Beowulf clusters.
* (KB) Met with software group to appraise state of various API's and
software technologies currently targeted for our alpha release this
summer. The DB2
server's daemon has had some unexpected failures. Verbose message
logging
has been enabled to try and track down the problem but no failures
have
occurred since enabling logging.
* (KB) Drafted a network diagram for the LDAS LAN to be configured at
Hanford in mid-June. The diagram is available in LDAS' ILOG and on
the group's
homepage.
Worked with Hanford general computing and CDS to identify acceptable
private networks and gateway IP numbers.
* (KB) Worked with Albert and staff to prepare for travel during the
June /
July time frame when finance has a blackout.
* (KB) Assisted CDS in benchmarks used to compare and contrast performance
of a Pentium III VME processor.
* (KB) Met with CDS to discuss the use of the Framecpp frame c++ class
library and the integration of Alex into several LDAS tasks.
Dave Farnham:
1) Created a Regex & RegexMatch class to wrap the POSIX regular
expression library. This is part of libgeneral .
2) Fixed the general library so that the PACKAGE & VERSION macros
are
not overwritten by the config.h file.
3) Added support for 'dist' and 'distcheck' targets for general library.
4) Modified LdasElement so that it now parses the 'name' attribute.
The
format for the name attribute is "name1:name2:name3: ...".
These
individual names are now available via the getName method
(which takes
an integer, defaulting to zero, as a parameter).
5) In the Generic API, the copyContainerElement, refContainerElement,
and getContainerElement methods now take a query as an
argument instead
of an index. So, one could type 'getContainerElement
$myctnr
name="time"' and it would return the contained element
with name equal
to "time". This looks for a case-insensitive exact
match.
6) Completed writing code and implementing methods in the Frame API
which allow one to convert any frame object into corresponding
light-weight data.
7) Implemented code to convert frame ILWD objects back into native frame
objects. This has been implemented for all but 3
of the frame classes.
Xiao Hu:
* (XH) turned the DB2 trace on.
* (XH) discussed GDS trigger table, LDAS event table,
LDAS frame table with John, Walid and Roy.
* (XH) worked on ilwd file.
* (XH) worked on SQL statements.
* (XH) worked on DB2 configuration to perform online backup.
* (XH) is keeping tracking the avialibity of db2 V6.1.
Barbara K:
* (BK) Continued efforts on the CDS system. Started on the forms
to
add/edit new channels. Reworked existing forms for the change
in the Acquire field.

Week of 5/20 (not included last time)
1. Tested metadataAPI against openlink driver and IBM driver
after Ed did some cleanup and released his new metadataAPI.so.
The working environment for metadataAPI in LDAS is defined:
genericAPI, metadataAPI, IBM driver Manager and Openlink
driver. metadataAPI.so has a core dump with the
iODBC driver
manager and we must have the genericAPI loaded first.
2. Attended technical meetings on metadataAPI interface and
LDAS alpha release scheduling for June-July.
3. Wrote metadata.tcl procs to read in Xiao's gds ilwd
simulation data file with the new genericAPI just
released
by Dave. Make the ilwd parameters and their data
pointers
ready for parameter binding when Ed releases metadataAPI.so
again. Also supported LDASevent ilwd file.
4. Make metadata.tcl procs with namespaces to be ready for
switch to concurrent mode of cmds when procs are
done.
Week of 5/27
1. With Xiao, worked out the sql statement to insert unique Ids
without the need of binding it as a parameter.
2. Attended technical meeting on metadataAPI interface and
weekly status meeting.
3. Added procs to metadata.tcl to output ilwd from query results
(strings for now).
4. Posted iLog entry on current environment for metadataAPI.
5. Make metadataAPI ready for LDAS integration by adding log
entries and slave interp to handle each cmd from
the operator
socket.
6. Tested metadataAPI for parameter binding with Ed's latest
release of metadataAPI.so.
Ed Maros:
* Added ilwd support for parameter binding
Bruce Sears:
* Ilog Issues
Designing several enhancements
to the Ilog system.
* Majordomo Configuration and Testing
Finished installation and
configuration of Majordomo for use
within LIGO. Set up
and tested 5 weekly report aliases (more
work than I was expecting,
actually.)

of what is
actually being done at the Observatory as well as getting an update
on their
proposal of putting in a faster network connection.
Hanford: (Christine)
Tried to install new patches for Solaris 2.6 and for Workshop 5.0
compilers, discovered that there is not enough disk space left to
install the patches. Ordered another 18GB external disk.
Rebooted the server to clear out old spool files, auto-mount the new
email accounts to the server, and removed a broken scsi tape drive.
Temporarily put one of the LDAS Sun workstations on the GC network along
with it's external 18 GB disk so that LDAS can use ftp to start
transferring software to LHO.
CIT:
(Barbara K.)
Updated spreadsheets with future plan for web services. Attended
a meeting
about the safety & ops procedures on the web.
Miscellaneous tasks for the Amaldi conference.

*** PLEASE NOTE *** Due to Caltech's conversion to a new Accounting System, there will be a "Dark Period" during which nothing new will be able to be processed. You are encouraged to make travel arrangements for your upcoming trips from now until August or be prepared to purchase tickets using your personal credit card. This "Dark Period" is scheduled to start on June 16th. HOWEVER, I have set my personal goal as close of day on Friday, June 11th, just to make sure I get your trips done. This also applies to Expense checks and Advance Checks. Thanks for your help. With your assistance we should be able to get through this.
Worked on preparing the paper work for various new trips taken recently (21 Purchase Requisitions and 19 Advance Requests). There are 29 additional new trips in various stages pending completion of travel arrangements, and still coming.
Completed all of SURF Travel except for the 1 student coming from Belgrade, Yugoslavia. His participating in the 1999 SURF Program is becoming doubtful. However I did hear from this week and he is still optimistic that he will be able to get out. The SURF schedule is from June 14th thru August 20th and many of LIGO's members are acting as Mentors.
Completed 31 Expense Reports, some of which were extensive, involving 2 or more pages each. Many of these reports were still not taped or completed by the Traveler, and required additional time for completion. Also worked on a number of problem issues which required a good portion of my time. Received, but not yet completed my audit, 13 Expense Reports. These should be completed in the next couple of days, barring unexpected delays. I'm still holding 6 expense reports which require additional information and/or missing receipts from the traveler.
Prepared Travel/Vacation Itinerary for the Week of May 24th, 1999.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as from members of the staffs of each of the two (2) sites.
Dorothy Lloyd
Began closing out inactive contracts and POs in IFIS in preparation of moving over to the new system Oracle. Continued to process heavy load of invoices for payment, and tracked and followed up on various invoice problems. Signed off on numerous PO receivers. Processed the usual heavy load of POs, reqs, change orders, check request, etc. (for further details see Cost Schedule Control System Report by Sarita Moore).
Continue to monitor and support the temp.
Elizabeth K. Wood
Dealt with many personnel issues. Many many personnel issues.
Would have attended an exhibition of Data Warehouse over at the APE house but the prototype was lost and will not be found for several days. Our confidence in the impending switch to ORACLE remains undaunted.
Also awaiting word on training for the new system. We wait with eager anticipation. And wait and wait.
Tracked down some missing ISDN lines for Larry Wallace.
Have begun helping Dot file a little paperwork.
