The Project Control Meeting
Agenda for Monday June 7, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Weekly
Report Highlights
LHO corner station seismic installation complete
for 2k IFO!
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #33 consisting of IOO optics MCCM2K01-1,
MCFM08-1 and MMT22K-1 was
released on 5-28-99.
Load #34 consisting of core optics 2FM01-A, 2ITM01-C was released on
6-1-99. The thermocouple wires for two of the seven heat zones were
crossed during
the first 20 hours of this load. This resulted in one of the
two running cooler (50C) than the setpoint (80C) and the other running
hotter (150C) than the setpoint.
Luckily, the zone that exceeded the setpoint is a small remote zone
that does not have a direct line of site in which to radiate to the optics.
As such, I don't believe
the optics' magnets exceeded their Curie temp.
Load #35 consisting of three HAM bellows is baking and is to be released on Monday 6-7-99.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
BSC7 Work:
The stack, including the Leg Elements and Coil
Springs, was completed and the Downtube was suspended on the Stack by Corey,
Stan W, Peter Saulson, Betsy
W, and Robert Schofield. The Kapton cabling
was installed by Josh Meyers and Corey; and the Counter weights were positioned
on the Optics Table by Betsy,
Corey, and Josh. The Fixturing hardware
was removed and the Dome and Door were replaced allowing Robert Scholfield
to take magnetic field measurements on
the chamber over the long weekend. It is
currently being pumped down. The Translation Stages were reconnected
to the Air Bearings (disconnected earlier for
leaky Bellows work).
BSC8 Work:
Switched out Translation Stages (see BSC4 explaination). The Optics
Table elevation will be set. This was done earlier but the first set of
Actuation Hardware did
not have all the Limit Switches installed, set, or tested; so, we can
now set the Table without worry of future swap outs which requires repositioning
the system.
BSC4 Work:
The remaining 70 lbs of Counterweights were installed on the Optics
Table while we were inside for the BSC7 work. The OSEMs were also
removed from the
Recycling mirror in HAM9 while inside. Near term tasks include
the swapping out of Translations Stages(Originals installed did not have
limit switches set,)
swapping the Flexure Fixtures for the Coarse Flexures(received LHO
6-3), and installing the cabling for the Coarse Actuation System.
CAS Rack:
Once the BSC8 Optics Table is moved back to nominal position, the Coarse
Actuation System Rack will be moved to its final home between BSCs 4 &
7. This
will allow the cabling (received LHO 6-1) installation to be completed
and the Optics Table to be positioned in BSC4. No cabling has yet
been received for BSC7.
BSC6 (Y-Mid):
The Mid station is crowded with much hardware and fixturing in preparation
for the SEI push there. The Roller System has been modified for use
over the Ion
Pumps and will be positioned near the chamber once the Turbo Pump has
been removed and the Adapter Plate Alignment has been completed.
We are waiting for
the X-Fine Translation Stages before the external hardware can be completed,
we expect this mid to late June.
Optics:
---------------------
(B. Weaver)
This week, Doug and I received the FMy and ITMy from the vacuum
bake oven and recleaned them. We then moved them into their LOS
structures and suspended them. We will verify their balances
next week,
and then they will be ready for re/installation. Today, I am
cleaning the
FMx to begin it's processing. We (not sure which group of we's)
will
glue magnets to the FMx next week. The ITMx has also been reinserted
into the processing cycle and will be back on schedule shortly.
I have also
been making up more magnet/standoff assemblies with Helena's new procedure.
Last week, Peter Saulsen and I pulled the OSEMs out of the RM in HAM
9 via
a short walk from BSC 7. Doug and I pulled the filters off of
them and cleaned
them up, so they are now ready to be reinstalled. While inside
the chambers,
Peter and I also added weights to the BSC 4 table (not enough were
installed
initially).
Along the lines of OSEMs, I've gathered and assembled all of the long
OSEMs
we have here at Hanford. We have 37 altogether, with 20 being
used this week
for the FMx, ITMx, FMy, and ITMy. I will be measuring all of
the OSEMs this
afternoon to verify their open light voltages. I will also serialize
them
so that
we can keep better track of them.
Computing Systems:
------------------
(C. Patton)
Investigated problems with the elm and pine mail tools on rainier and
apex. Did the usual weekly backups, reconciled my LHO GC budget with
financial reports,
and added/modified a couple of user accounts. Helped a user with
a mail tool problem. Worked with FORE Systems to get a quote for
the LHO ATM equipment
maintenance contract. Rebooted the server after it crashed, apparently
from a print job. Ordered more licenses for the Workshop compilers
for the CDS server.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
The turbo and cryopumps have been removed from X2-1 and 9. Both
ports have been baked after reinstallation of the "H" hardware. Port
X2-9 failed the leak
check. Upon disassembly and inspection found a crack(very tiny)
in the copper gasket. The gasket was replaced and the port has been
re-baked. Port X2-1
passed the leak check. The RGA has been removed from port X2-5,
baked following installation of the 4.5" conflat. The port
passed the leak check. PUD(Public
Utility District) came out Tuesday and disconnected all power to the
beam tube bake out transformers. We completed the loading of 2 20'
containers full of bake
out equipment and
sent it on to Livingston. We sent 2 more Cryopumps to CVI for
refurbishment. These will be sent directly to Livingston upon completion
of work.
CDS: The Livingston CDS web site will be ready for viewing in about a week. I have left several messages with Proxima trying to arrange a demonstration of their multimedia projectors in our control room. No word back yet. We have received four 162 processors from Hanford for the IO rack and suspension test stand. Xycom XY220's were shipped to Hanford on Friday, May 28. We should receive ours from Hanford in about a week. SOS controller for the suspension test stand has arrived. Cable tray in the corner station is about 90% complete. We have been held up due to stack assembly in HAM's 2 & 3. We will finish the corner station next week and move on to the end stations. (Russ Wooley, Juilien Svoboda)
Optics: The next bakeload of the LOS for MMT-3, as well as a large batch of SOS hardware is in the oven, thanks to Jordan and Gary. The SS baskets I ordered worked well for managing small SOS bits-n-pieces. I completed the installation of the ISC groutplates in the end-stations. One of the groutplates was missing a clearance hole for a monument, so Jordan located it for us and we had Southern hydro-cut it in their shop. Inspected the two new flowbenches, and sketched out two frames to support the 4" breadboards. Working on the machine shop when time permits, and obtaining bids on a suitable mill and toolroom lathe. (Jonathan Kern, Tom Evans)
Beam tube bakeout: DEMCO (local power provider) visited the site in preparation for installation of power cables to the bake out transformers. The LLO HV lines have a different connector than LHO. We are looking at several options for modifying the cables sent from LHO. We should have power by 6/14 to begin installation of the data acquisition system. We have interviewed several people to support bake out, and will be getting them on board in the next 2 weeks. (Allen Sibley, Cecil Franklin, Kerry Stiff)
General computing: We have been getting prices for the remaining
software packages we need. (Tom Evans)
ISC Design and Fabrication (K.Mason, M. MacInnis)
-----------------------------------------------------------------------
The design and assembly drawings of the dark port ISC tables (WISCT10,
WISCT4, and LISCT4) have been completed. The preliminary drawings are
D990135-0-S1 and D990135-0-S2 and are located on the Caltech ftp site
at
/pub/kmason. The drawings are in dwg and pdf formats.
Myron has assembled a clean room and has begun assembly of WISCT10.
ISC fabrication and installation (Matt Smith)
----------------------------------------------
Had all of the riser block machined by Larry Larson to accomodate the
isolation of the photdiode from the facility ground. Reinstalled
all of
the riser blocks and photodiodes for the 2K RM, BS,Y-ITM, and
Y-FM. (Used
Kapton tape as well as an isulating bushing). Checked with volt
meter and
it was okay. As we get more photodiodes we will install them
into the
optical lever assemblies.
Installed beam tube between the optical lever for the 2K fold mirror
so
that John Worden can reroute the annulus piping to the gate valve.
Replaced the photdiode on the 2K RM.
RFAM noise measurements (Kells/Mavalvala)
------------------------------------------
The 29.5 MHz photodiode was repaired and reinstalled in the IO beam
to
measure the RFAM noise with higher light level. Some small contributors
to the IF noise spectrum were eliminated, e.g. light reflected from
the
PD itself. The RFAM noise is at the shotnoise level at ~700 Hz and
about 3 dB above shotnoise around 150 Hz. There are some resonant
features in the spectrum but there is a clearly identifiable continuum
of excess noise. We are still looking for the source.
We are also exploring a procedure for alignment of the EOMs that
minimizes the RFAM and of course preserves maximum throughput.
We took a first look at the intensity noise form the laser at low
frequencies (few Hz to 10 kHz). The calibrated numbers are still
to be made but the spectral content looks quite different from the
IF spectrum of the RFAM.

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 intra-MOPA EOM has been installed in the LLO PSL laser.
- The LLO PSL reference cavity vacuum chamber has been positioned on
the
IOO/PSL optical table and is currently being pumped down by the 20
l/s ion
pump.
- Periscopes to step the beam down to the optical height of the PSL
(approx. 76 mm) have been installed. In addition an attenuator,
comprising
of a half waveplate and polarizing beamsplitter cube, has been installed.
- Half of the remaining zero length vacuum viewports for the other reference
cavity vacuum chambers are scheduled to ship by the middle of next
week
(06/07).
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
Hanford 2-k IOO
Sany Yoshida is at LHO now. David Tanner and Dan Dickerel will be there
next week.
SOS Preparation
All suspended mirrors survived the vacuum preparation and have been
placed
in the HAMs. We have installed five 1" optics on fixed mounts
(T-mounts)
on HAM7. During this installation, we noticed that two of the three
T-mounts that were already on HAM7 had the optic holder (the cylindrical
holder) on the opposite side of the mount. (The cylindrical holder
was
stickong out to the rear side of the mount.) We corrected these problems.
All the 1" optics have been aligned with reference to the screw holes
on
the HAM table. Now we have placed all the optics on HAM7. The
in-vacuum
IOO components are essentially complete.
# DHS GREAT NEWS.
PSL/IOO table
We have installed a calcite polarizing beam splitter cube (PBSC) after
the
lambda/2 plate near the IOO/PSL handoff location to facilitate reducing
beam power. This will be a permanent installation.
The forward-going rejected beam from the PBSCs (one to be placed as
described in item 1, above, and the one just before the EOMs) will
be
dumped in an OptoSigma beam dump. We will eliminate the razor
blade dumps
because they are oily. D. Tanner is oversing the procurement
of anodized
aluminum dumps that encircle the PBSCs mounted in rotation stages.
IOO
will install them. When - forward-going dump with temporary encircling
dump at time of installation of PBSC. Permanent encircling dumps
Right
now, an OptoSigma beam dump and 2 anodized aluminum dump sheets are
used
for the volume control unit installed last Friday.
The status of the permanent units is that they have been designed and
a
prototype made. They are in the shop now.
In addition a cover to protect the back of the mirror mounts has been
designed and a prototype made. They are in the shop now. This unit
is
mainly to make tampering a little more difficult and to protect the
adjustment screws from inadvertant nudging.
Mode Matching Measurement for Single Arm Cavity Test
Guido has completed the layouts and the calculations for the bullseye
measurements.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Measurements are complete for SPETM03, the first of the pair which has
been selected to go to Hanford. This optic will go to cleaning
June 7th
and should ship to Hanford by June 14.
We have reported longer radii of curvature for the SPETMs than
anticipated, however matching appears to be quite good. There
has been a
flurry of e-mails and analysis (many thanks to
Bill Kells) last weekend.
It is my current understanding the longer radii
are acceptable, and that
we will be using the SPETMs as they are.
Michael Hrynevych and I are at NIST, we are currently comparing seismic
data between NIST and the CRL at Caltech. It appears that the
NIST campus
is quieter than Caltech. The probe used for both measurements
is the
same, however the spectrum analyzer is not. The difference is
fairly
significant, so we are double checking before reporting exact results.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO Contract - COC's coatings. We coated the HR side on a pair of 4kITM's.
Coating looks good. Made the decision not to
coat 4kITM01. The surface looks
stained and cloudy. We tried for two days to
get it clean by different
approaches without success. The stains are going
to look more prominent
after coating. It looks as if the polishing compound
was not properly
removed and cleaned after polishing. A third
4kITM, HR side, is getting
coated today.
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE
4 primary mirrors will be sent to REO by 6/4 for coating. 3 secondary
mirrors have completed polish and are being edged. 3 more secondary
mirrors
are expected to be completed by week of 6/11, and it is expected that
4
secondary mirrors will be shipped to REO for coating by 6/15. Ken M
is in
the process of cleaning up the production drawing package.
ETM TELESCOPE
Ken M. has completed the production drawing package for the ETM. A
bid
package will be sent out the week of 6/7.
PO MIRRORS
The BS PO mirror assembly, to be installed in BSC7, will be shipped
to LHO
for clean and bake the week of 6/7.
CAVITY BEAM DUMP
Delivery for all of the beam dump structures in BSC1, BSC2, BSC3, BSC4,
BSC7, and BSC8 of LHO and LLO is expected by the week of 6/14. Some
of the
parts are expected the week of 6/7 and will be shipped to LHO for clean
and
bake. Awaiting AR coating of the glass for the plate beam dump. Craig
C. is
completing the assembly drawings for the beam dump installation.
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. C-mount lens adapter spacers
and
filter holders are expected by 6/4. The IR filters have been sent out
for
edging.

Seismic Design (Mike Fine)
--------------------------------------
1. Electronics Rack
Progress is continuing with the rack assembly. Due to the programmatic
needs for BSC cabling and junction boxes Hytec has not completed the
internal
wiring as expected. This has pushed their schedule back by three
to four
days. They are expecting to complete the rack by the end of this
week and
hoping to turn the rack on no later than Friday. Debugging and
software changes will need to take place at this time.
2. Scissors Tables
Hand Precision is continuing on the scissors table assembly for the
April
and May delivery. They have not completed them as of today, but expect
the
machining to complete next week. Hytec will assemble as many
BSC scissors
tables to be delivered on the next shipment to LLO.
3. Near-Term SEI Hardware Delivery Schedule:
1 BSC Downtubes (Livingston) 6/8
2 BSC support tubes (Livingston) 6/8
1400 # counter weights

(WBS 1.2.1.1.9)
---------------------------------------------------------
Global Diagnostics System
(Daniel Sigg, John Zweizig)
Finished a Filter class and related utilities for use in the root
environment. Also isolated and reported several bugs tripped
over in root.
Most of the time spent debugging the sine response test code.
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
4. The preliminary version of the Particle Detector
design has been
sent to interested parties and possible sites for discussions and comments.
5. We are updating the PEM-FD with the latest indications
and
modifications.
3. Matt is in Hanford and sent the following report:
Assembled all of the PEM stay clear zone railings for each building.
The
baseplates will be remade by the vendor and will be installed later.
Installed one of the Beam Tube interface plates. Will install
the rest of
them Thursday. Modified the 3 channel Wilcoxen signal conditioners
to
install them onto the beam tube support cross braces. Made a
bracket to
install the signal conditioners to the support cross braces.
Installed accelerometers onto the 2K PSL, WHAMs 7,8,9 and 10, WBSCs
7 and
8. Ran the cables for all of these. Also ran the cables
to WBSC4 but
there are no PEM interface plates or accelerometers installed due to
leak
checking to be done. Installed a microphone into the 2K PSL.
Installed the software and dongle for the RGA at the Y MID station.
The
RGA software is Quadstar 421 for now. No RGA scan has been taken
though,
since the chamber is not currently being pumped on and is at a pressure
of
~5 x 10 ^-6. I am still trying to get the new software from Balzers.
I am
not getting a good response from Balzers on this issue. They
seem tobe
dragging their feet on what to do about helping me. Finally they
said
that we would have to pay for the upgrade and were suppose to
send me a
quote on the new software earlier this week.

Control and Data System -- R. Bork
(WBS 1.2.2)
-------------------------------------------
PSL (Rich)
============
1. Preparing items for my upcoming trip to LLO (3 June to 11
June)
2. Working on the final Frequency Servo card after upgrading to
new cad
system.
3. Began initial phase of design on new Intensity Servo card but
need some
data from the new AOM. That data will be gathered during the
trip to LLO.
LSC (Rolf)
==========
- Completed timing tests of LSC servo code on Pentium III VME processor.
Timing
comparisons of this board and present CDS 200MHz Mips processor board
(requirement is under 62usec total time):
Interrupt Filter
Total Time
Latency
Calculation w/all necessary
Processor Time
I/O operations
---------- --------- ------------
---------------
Mips <500nsec
37usec 61usec
Pentium III 5usec 16usec
56usec
Pentium was much faster in calculations, but slower in VME access,
particularly
VME bus reads. We can possibly get around this by using the PCI bus
to
reflected
memory instead of VME to reflected memory. Factory rep thinks this
would be
more
than three times faster and he will perform some tests to verify this
by
the end
of the week. If this turns out to be true, the Pentium total times
could be
down
to <40usec, giving us a more comfortable margin on the specs for
additional
computation, which is sure to come as the system is commissioned.
ASC (Jay)
==============
- The WFS Whitening Board has been received from the vendor. Two boards
will be
stuffed and tested for the 2K one arm test.

Suspension (Jay)
=================
- Cross connect wiring for LLO 4K COS on hold for LHO 2K jobs.
- Suspension controller for LLO test stand completed and sent to LLO.
EO Shutter Controller (Sander)
===============================
Three front panels have been fabricated and the silk screen
is in house.
Because of the small quantity, Jay will use his credit card to get
the work
done
at a local print house.
DAQ Antialiasing Filters (Sander)
===================================
A. BNC Version
PCB for the BNC version board
is in house. Except for the filter
modules,
all other components are in house. Phoenix will put one
together as soon as
the modules arrive.
B. LEMO Version
Because Fred did not work on the
board while I was on vacation, I have
taken over the design job myself. This task should be completed early
next
week.
Mode Cleaner CDS (Dale):
================
The programmable delay from gigabuadics arrived at Hanford. It will
be used
for tuning the RF/LO phases of the demodulator board.We will then trim
the
cables to exact length. Updated control screens for the Length Servo
will
be tested at Hanford this week.
Timing System (Dale):
===============
The Clock Fanouts have all been tested. The Clock Driver that produces
all
of the timing pulses and sequencing is being tested now. I will be
bringing
it with me to Hanford next week to test on the system. Six more GPS
antennas arrived from Brandywine. These will be shipped to Hanford.
LSC One-Arm test, CDS (Dale):
==================
I have started designing filter boards and demodulator for the analog
LSC
servo. The demodulator circuit will be close to the final LSC design
but
will be a prototype because it will not have all of the packaging
considerations of the final design. The filters are strictly prototype
but
will provide useful information fro final LSC filter implementation.

Press here for ACCOUNTS PAYABLE HISTORY DATA.
From: Kris Duncan <kris@ligo.caltech.edu>
No report this week.
Hiro started to include the numerical integration method developed
by Peter Fritchel for GDS's swept-sine measurement as a part of e2e.
Hiro modified the interactive I/O part of e2e so that comment can
be included in the recorded input file.
Peter feels that the speed is becoming an issue.
Hiro compiled
modeler/modeler_freq with the highest optimization,
and copied to
ligo.mit.edu. Conrad will work to find the bottleneck
using a
profiler. Hiro completed a few digitization
routines (A2D_sampler,
VAL_digitizer, and updated digital_filter) and they are documented.
They have not been cvs-ed yet.
(IOO modelling)
We had a two-and-half hour telephonic conference on IOO simulation
effort on June 2. It was attended by Sergei (Florida), Haisheng,
Malik, Rick (LHO), Biplab, Matt (Caltech). Sergei and Malik
presented their recent work on construction of E2E simulation
boxes for optics and control system parts respectively. People
could get a broad and general view of the kind of IOO modelling
problems that we need to face in next few weeks. Some of the
detailed issues on naming conventions, proper input and output
ports and rearrangement of connected modules, acquiring and
managing various parameter values were also discusssed.
In next few weeks Sergei and Malik will try to work together to
(i) run their own boxes separately, (ii) combine their boxes
together (iii) start some validation or shake-down runs.
Merger of IOO with PSL work (being done by Biplab, Rick, Hiro)
involves issues related to merger of codes (for some primitive
modules) developed by Sergei into Adlib and are to be addressed soon.
(Alfi)
(EFM) Ed Maros continued his work on using automake and autoconfig.
(Conrad's week)
o read the following documents:
- Getting Started with End-to-End model
- Overview of End-to-End model
o created a simple script for setting up the E2E environment
o reviewed Adlib source code
* (KB) Met with the LDAS software group to discuss status and progress
as our usual Friday meeting will
not take place this week. Among
the most significant accomplishments
this week is the successful
building and testing of the XML
parser library from IBM using
the egcs compiler on Solaris [see
M Barnes' weekly]
* (KB) Met with Phil and Mary to go over the model of the macros used
by the managerAPI as it controls
process flow in the LDAS APIs.
This cleared up several points
on the usage model and resulted
in a second generation of high
level commands for getting data
from LDAS (frame and/or metadata).
* (KB) Met with Phil Mary Dave and Ed to discuss the SWIG interface
as
it is used by C++ classes and
presented to TCL. This enlightened
all of us and will provide for
a more TCL "look and feel" to the
C++ class wrappers used in TCL
code and helps to improve the
readability and hence the maintainability
of the TCL code.
- DWF modified the AttributeValue class in the ILWD library to
automatically convert illegal characters
(<>&'") into references
when writing the attribute. For
example, the string "vector<int>"
becomes "vector<int>".
When reading in the attribute, the
references are converted back into their
character form.
- DWF continued implementing the conversion of ILWD objects to FrameCPP
objects in the FrameAPI. This
is approximately 90% complete, it
should be finished this week.
(EFM) Installed DB2 Server 5.0 on deneb
(EFM) Installed DB2 Client for Solaris7 testing on denebola
* XHU modified LDAS frame tables
* XHU modified GDS trigger tables
* XHU created more ilwd template files
* (PSE) Migrated queue saving/restoring code from manager
to generic API module.
* (PSE) Tested existing installed software (on SPICA) on
DENEB, an ultra2 running
64-bit solaris 7.
Everything seemed to work
fine, including the
genericAPI.so and the frameAPI.so.
* (PSE) Demo'd the current state of the manager and frame API's
to Kent. This pointed
up a number of small bugs.
Fixed the bugs.
* (PSE) Changed format of meta-options for user commands so that
each user command supplies
it's own option prototypes and
defaults.
Phil's weekly from last week:
* (PSE) Wrote functions for the frame API to cache 15 minutes
of frame file absolute path
names, and continuously
update the cache with the
continuously broadcast frame
names, using the 40 meter
broadcast as a prototype
source.
* (PSE) Helped Ed to synchronise the installed tools on SPICA,
KITALPHA, and SADAN to ensure
consistent development
tools on Solaris, Linux
x86, and Linux ALPHA platforms.
* (PSE) Tested a variety of the packages installed on SPICA for
runnability on DENEB, which
is an Ultra2 running 64 bit
Solaris 2.7. Everything
I tested ran as it does on 32
bit Solaris 2.6.
* (PSE) Installed Tcl/Tk 8.1.1 on SPICA.
* (PSE) Wrote a small document describing the format of messaging
at the various levels of
the LDAS system. This will be
posted soon on the development
pages.
* (PSE) Met with Mary Lei to discuss the design of the metadata
API and it's incorporation
into the LDAS system.
* (BK) The individual forms for the CDS application are complete.
Next
they will be assembled into user
and administrator views and tested
more rigorously.
* (MB) Met with Dave and Phil to get information on GNU and SUN compilers.
* (MB) Checked IBM's XML V2.1.0 software supporting Solaris into the
repository.
* (MB) Built IBM's XML parser library with g++/gcc compilers.
* (ML) Prepared metadataAPI for integrating into the LDAS environment:
added logging via genericAPI;
have a new log for each slave
interp; added exception handling
to return errors to top level;
changed metadataAPI so to return
database errors to tcl.
* (ML) Attempted to make a safe interp for metadataAPI statement
execution but it was too restrictive;
will instantiate regular slave
interp with restrictions on
opening files.
* (ML) Discussed with Phil on writing macros for manager.
Majid:
As part of an effort to get the Algorithm library off the ground, I
attempted to work on Welch's method to estimate the power spectral
density. I have conceptually divided the algorithm into its atomic
units,
in the hope of reusability of code as well as its modularity. I am
planning on proceeding with the implementation of this algorithm after
a discussion with Sam Finn and Bruce Allen of LSC.
Stuart Anderson
Pre-staged and established
regular mirroring of the standard LDAS
software tools (20GB) to LHO in anticiplation of the initial LDAS installation
at LHO in mid June.
Crashed the High Performance
Gateway Node (HPGN) interface into
the new CACR HPSS system 4 times. CACR has raised the problem with
IBM
as a high severity problem under existing software maintenance contracts.
Arranged for CACR to order
15TB of HPSS tape storage from a
LIGO account (with appropriate LIGO tape labels) to be used for
O(10TB) LIGO HPSS tests using the existing CACR hardware.
Upgraded the LDAS Linux Beowulf
cluster to RedHat6.0 and established a
significantly simplified procedure for bringing up NIS+ services on
Linux
machines running RedHat6.0 for easy integration of PC's into the existing
LIGO/CIT network.
Continued active research
into 1TB class disk cache systems for LDAS
with the most recent meeting being with Andataco an OEM partner for
Clarion
Fibre Channel RAID systems.
Lazzarini
Met with Sam Finn to iterate on the numerical algorithm
library for LIGO/LSC
development.
Livingston:
Sent in data of SUN boxes to be added to the Caltech site licensing
program.
Hanford:
Investigated problems with the elm and pine mail tools on rainier and
apex. Did the usual weekly backups, reconciled my LHO GC budget
with
financial reports, and added/modified a couple of user accounts.
Helped
a user with a mail tool problem. Worked with FORE Systems to
get a
quote for the LHO ATM equipment maintenance contract. Rebooted
the
server after it crashed, apparently from a print job. Ordered
more
licenses for the Workshop compilers for the CDS server.
CIT:
Barbara reviewed the plan for web services with Gary and received an
ok to
proceed.
- Resolved problems converting several long LSC reports to PDF.
Access had
problems paginating the memo fields in the report. Then the pagination
didn't hold when the report was transferred to Word (the "Publish
with
Word" feature isn't quite what it seems). Cleaned up one report
that had
unprintable characters sprinkled throughout. Helped connect Irena to
the
server with the LSC reports database.
- Continued to help with Amaldi items -- applications, abstract
registrations, web site changes, submission of papers, etc.
The number of people using the CD burner has increased and the requests
for CD's
has also been on the rise. We are now looking at the DVD burner and
trying to
get a few people to test it out but so far it is looking pretty good.
Suresh is
also trying to clean off a number of dead accounts on the server and
will be
transferring the data from those accounts to CD, this includes a number
of
people that are now working at the Observatories and are no-longer
stationed at
Caltech.
Checking on procurements and tracking down related issues has taken
a deal of
time. Also, getting orders out the door before the blackout period
has taken a
higher priority.
A number of machines have been moved along with some new installations
to
accommodate various areas. Presently, working on the installation of
the new
version of cadence on to a new server.
Once again we are working on cleaning off a number of PC's that have
been
infected with viruses. The latest versions of virus-scan need to be
loaded on
all of the PC's. The older versions are not detecting this latest batch
of
viruses.
Monthly backups are being performed at this time. There was a delay
because of
some problems with a couple of the tape drives.
We just received a number of network units that we plan on installing
in the
next couple of weeks. One is to be used for the CITNET2000 connection.
The other
unit will allow us to check things out for the swap over to the new
FORE box.

*** 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 (34 Purchase Requisitions and 36 Advance Requests). There are 25 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 him last 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 14 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, 29 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 June 2nd, 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.
Rita Torres
Non-stop action this week. For I Petrac formatted MOU with Tokyo University, also Attachment 1. Did RFQ IP-311 for Creep Measuring Fixture, prepared letters to four bidders, did subsequent edits; obtained 6 sets of large drawings for same and sent all FedEx. Began an Excel list of LSC members, listing their affiliations and email addresses. Did letter to K. Danzmann Re: MOU attachments, prepared FedEx. Did change order No. 6 to K. Creath, change order No. 4 to Lightwave, and change order No. 5 to CRDF.
For E. Jasnow began input to RFP EJ-312 for Electrical Contractor Service for the Beam Tube Bakeout at LLO; 26 pages.
For W. Tyler/M. Zydowicz did edits to Safety Program then distributed for review. Also did edits to Safety Program then verified web links called out, need to find correct links. For W. Althouse continued search for special items, am coordinating with vendor. For admin group continued updates to LIGO Roster (home information), did final input on 6/2/99. Thanks go to C. Mak who will distribute for us
Dorothy Lloyd
Continued working on closing out inactive contracts and POs in IFIS in preparation of moving over to the new system Oracle. Processed a 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.
Elizabeth K. Wood
Talked to Veronica and Valeda about issues that are pending with the Amaldi conference.
Continuing to do personnel paperwork before the dreaded dark period descends upon us. Hiring freeze begins at the close of business Friday, June 11.
There has been a suggestion that we start a pool concerning when/if the ORACLE demonstrations/training for LIGOites will actually begin.
Handled on-going personnel issues.
Made arrangements with Criselda to get two more people into the P-Card Classes.
Spent part of Wednesday and Thursday trying to locate whatever became of LIGO's petty cash reimbursement that I sent over to Business Services almost three weeks ago. End result: the 9" by 12" package has vanished. And I thought black holes were only in outer space.
Tracked down some mysterious phone numbers for Larry Wallace. Found the owners.
