The Project Control Meeting
Agenda for Monday February 1, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Weekly
Report Highlights in blue below
General Items:
--------------
(Fred Raab)
This week saw the successful re-balancing of MMT3 and scurrying to get
alignment
fixturing whipped into shape. (Read that: "Don't expect a report from
Doug Cook
today!)
(GHS note: Balancing did not succeed without
removal of spacer rod. So regluing, baking is needed. Mark Barton and Helena
have started. In the meantime, another MMT3 was installed in HAM7 today
as a stand in to permit an alignment run through. Many lessons were learned
in this exercise.)
We had a video crew out taping material for an educational video, called
"The Scientific Method at Work", whose purpose is to give kids an idea
of how
science and math get applied in real-life science and engineering workplaces.
We
should get some good video and graphics material for LIGO outreach
from this
program. The demo Michelson interferometer put together by Rick Savage
and
Russell, a student from Southridge high School, made a big hit with
the video
crew.
Professors Braginsky and Mitrofanov are visiting LHO this week and were
kind
enough to give an instructive seminar on their work at MSU. We hope
that many of
our visitors will follow their example in future.
Facilities:
-----------
O. Matherny
New Construction: George Grant Construction Co. placed concrete for
the building
floor slab. Two thirds is complete.
Water System modification: Apollo is 75% complete with the water modification
project. The 8000 gallon tank was delivered but not yet plumbed in.
After
examination of the water tank we rejected the tank for cosmetic reasons.
The
insulation was installed extremely sloppily, and the tank looks like
it is made
from paper. The supplier is taking the tank back to the factory for
re-work. This
will add a two week delay to the completion.
Compressors: We requested Sullair to give us a quote for replacing the
10
compressors with units that are compatible with our environment. The
new
compressors are approximately $60K. We are in process of trying to
get our money
back from Kaeser, since they guaranteed that we will never get any
oil in our air
lines.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
Leveling and setting of elevation on HAM 7 Optics Table was done with
the help of
Hugh's surveying skills and Larry Jones. This went well. We didn't
install the
remaining 240 (of 500) lbs. (we did account for the loading of the
springs with
this additional weight and set the elevation accordingly however).
One concern
was raised about the w-adjustment (via Scissors Tables), and that was
the concern
of uneven loading between the Vertical Stop Bolts and the jacks; will
look into
ways of correcting this on next elevation adjustment.
Will receive Air Bearing next Tues (2/2); this will enable us to install
Air
Bearings, install weights, fix cabling, and set elevation for the Optics
Table for
a hand off for Recycling Mirror installation later that week.
The installation of out of vacuum BSC8 components was completed this
week,
including the complete actuation stack and the crossbeam. We
continue to
complete the many small tasks as we gear up to in-vacuum installations
~2
weeks away.
The south door on BSC8 has been removed and preparations are underway
with
MIT for the initial alignment of MMT3 and the RM.
Computing Systems:
------------------
(C. Patton)
The General Computing network is now accessible from the LVEA. I will
be setting
up two P5-90 PCs for general use. I have also put out two 4 port hubs,
which can
be used to plug other computers into the network. One hub is behind
the vacuum VME
rack on the X arm, the other is behind the vacuum rack on the Y arm.
If you do
plug a computer into the hub, be aware of others
and safety considerations with
computer cables and power cords.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
The RGA and calibration cart have been installed at X1-5, leak checked,
and is
currently being baked. The Cryopump at X1-2 has been installed and
leak checked.
Sun River has completed all blanket installation and check out at the
mid and end
stations on X1 module. PUD (the local electric power company) has disconnected
the transformers
on
Y1 arm and Sun River has moved them to the X2 module. We are going
to test the DC
power supplies Thursday (1/28/99) to verify operation and control.
We should be
ready to begin the bake out of X1 module next week.
Preparation for beam tube bakeout (Cecil Franklin, Kerry Stiff): We have received the bid package from Caltech for the insulation work for the Beam Tube X &Y arms. Also an advertisement was placed in the Baton Rouge Advocate that will run for six days, stating all the details pertaining to the job. All local contractor packages will be mailed from the LLO Livingston Observatory site. All other Bid packages will be mailed from Caltech. Beam Tube thermocouple installation has been completed on the X-1 Module and also on the Y-1 module. The X-2 and Y-2 modules are each approximately 60% completed.
Seismic Isolation Installation (Rich Riesen, Joe Giaime, Tom Evans): All HAM and BSC Pier layout is completed in the LVEA and both End Stations. 4 HAM's and 3 BSC's in the LVEA and 1 ea. BSC in the 2 end stations. Core drilling has begun for the BSC's in the LVEA (4 holes are completed on BSC#2). All HAM's (4ea.) anchor bolts (64 total) have been installed in the LVEA. High-Presser water w/detergent cleaning has begun on the grouting plates. HAM pier cleaning will start tommorow
Optics & Vacuum Labs: (Jonathan Kern): The Culligan RO/DI
system remains erratic. Culligan installed a new circulating pump which
allows the system to
remain on all the time, however water quality has suffered. The best
we are doing right now is 10 mega-ohm water. Some stainless components
in a flow meter are suspect.
Our second 4x10' optical table has been placed in the lab. We've decided
to hire a local cabinet shop to repair the shipping damage to the flow
benches, at Air-Tech's expense. About 1/2 of the optics hardware has been
received from Opto-Sigma. The PSL safety enclosure (in plant office) has
yet to be ordered;still waiting for final comments from interested parties.
Electrical installation (Juilien Svoboda): LVEA network:
Ropes, Cat 5 cables, fish line and electrical tapes have been bought for
the cable installation in LVEA area. It's scheduled to start today with
Tom Evans' help. I hope that we can finish this project in 2 days.
Fiber Optic cable installation: The contractor for intallation
of the fiber optic cables has finished installing more than half of the
jacketing of the fiber cables in the BTEs. He is trying to increase the
number of the workers to finish this job earlier. I estimate that this
will take another two weeks to finish. When this is completed, Rolf and
I will do the final testing together with MCA.
EE lab: I am organizing the documents for the electronics instruments
in the EE lab and putting electronics parts away in a neat manner. This
is going to be an on-going project next week. I am still having trouble
with the shelves we bought from Equipto. Side and back panels have minor
damage due to shipping. I am trying to talk to the
vendor to see how we can resolve this problem.
VME test stand: Rolf generously let me use the CDS group's spare
19" rack and VME crate for our test stand in the EE lab. This will save
us money and time in the process. I have installed the test stand in the
lab. The software interface and a VME CPU processor board will be needed.
Currently I am borrowing CDS's SUN station and a CPU card to start the
initial test.
Anthony Rizzi: The end-to-end model software has been put on
a Sun and preliminary installation tests were successful.A Sun station
to be used for learning the CDS system and for exploring system feedback
issues has been set up in the room across from the Control room. I am in
the process of identifying VME hardware that will be needed. Jay Heefner
is investigating the status of the EPICs license at Livingston. I will
give the colloqium at LSU on Thursday on the
angular momentum work in general relativity.
The PEM cart computer can now access the Local Area Network but still
cannot be accessed by other LAN members.Tech Master has been asked
to look at this problem; they have investigated the problem and are
still in process of troubleshooting.
Facilities issues (Gerry Stapfer): The manufacturer representative for the expansion joint was onsite to check what kind of fix to recommend to Hensel Phelps. HP will then make a recommendation to LIGO regarding how to proceed. Bernard (the mechanical contractor) is continuing to work on the punch list and as part of that we found that the damper valves in the return ducts in the LVEA are either defective or need readjustment. We have contacted Siemens to address this problem - they will be here next week. We were informed by the sewage maintenance company that unknown persons dumped a load of grease into our sewage treatment plant. The Livingston Sheriff's office was informed and a report was filed. We requested a cost estimate from Sicord Inc. to fix the bullet holes in the west end station wall panels. The proposed method is the same as that used by HPC - to put a sheet of matching material over the damaged panel.

DETECTOR GROUP -- Whitcomb/Shoemaker
40 m Interferometer (Nergis Mavalvala)
---------------------------------------
40m Interferometer
The 40m is vented for mirror cleaning and installation of a
variable attenuator in the recycling mirror. Three of four
test masses were cleaned using a CO2 snow gun. On the south
end there was visible dust/dirt that was cleaned up by the
CO2. On the south vertex mirror significant scattered light
from a HeNe illuminating beam was not improved by repeated
cleaning. The east vertex HR surface is difficult to examine
but we believe some visible dust was removed by the CO2.
We plan to complete east end mirror cleaning and installation
of the variable attenuator in time for a Friday midday pumpdown.
Many thanks to Jim M, Phil W, Steve B, Daqun L, Shanti R, Eric B
and all other volunteers who have helped with the vent this week.

1/18
IOT7 on site
ISCT7,9,10 (Wa2k) to be assembled on site starting mid-Feb
ISC implementation (Fritschel)
--------------------------------------
o Ed and Peter discussed with Jay and Lori the near term program for
ISC code development. We are working toward a combined test of parts
of the supervisory controls and the ASC front end servo code in
mid-February at Caltech. Specific components we intend to have ready
for the test are: the DDCU (digital data collection unit) code which
communicates with the DAQ system and moves DAQ and diagnostic data
to&from the front end servo code; the EPICS code and control screens
for control & monitor of the ASC system. Lori will provide the
complete ASC front end servo code (polishing up what she has already
done).
o Began procurement of equipment we will need at the sites for
assembly of future ISC tables.
ISC implementation (Nergis Mavalvala)
--------------------------------------
WIOT7 status:
* beam alignment checked for both beam lines
* both periscopes installed
* mechanical shutters in place
* all optics bolted down, i.e. IOT7 ready to pivot
MC alignment WFS heads could not be tuned and will be done
during next visit to Hanford.
ISC supervisory controls (Daw)
------------------------------
This week Peter and I figured out a list of data acquisition
channels for the ASC and LSC digital data collection units (ddcus).
Rolf is now ( or has already ) inserted the correct channel names
and rates into the Hanford data acquisition system configuration
manager. I will update my ddcu code at Hanford to collect the
relevant data.
ISC fab (Smith)
---------------------------------
The table, legs and support piers for the optical levers to the input
test masses were ordered. I changed the optical enclosure drawing
to
include holes for the support of the acoustical blankets. The
blankets
were ordered(1 set) and should be at Hanford in two weeks. The
wedge
supports for the optical levers for the recycling mirror has not
arrived yet. They were shipped Monday, Jan 18.
IAS Initial Alignment (K.Mason, M. McInnis)
----------------------------------------------
Installed mmt3 support, laser, and photodiode
outside of Wham7 at
Hanford. A chart recorder is being hooked up
to monitor the orientation
of mmt3.
Two additional monuments have been placed along the Y-arm to align mmt3
and the recycling mirror through the door in BSC8. The alignment
equipment is being set up to align mmt3 which is expected to be
available friday morning.
[1/21 report]
------------------------------------
Interferometer sense/control (Zucker)
---------------------------------------
Announcement: We are sorry to say that Brent
Ware has announced he
will be leaving LIGO shortly. We thank
him for his outstanding
contributions to ISC lock acquisition simulation
and design, and look
forward with confidence to implementing them
in the real world. Good
luck in your future endeavors Brent!
ISC implementation (Nergis Mavalvala)
--------------------------------------
Documentation and parts for installation of WIOT7 received and
alignment checkout is underway.
WFS Guoy phase telescope (GPT) design for 2km antisymmetric port
sensor completed, accounting for COS beam reducing telescope. Since
the beam from the 8X reducing telescope is a quite large (~4 mm
radius) the GPT design needed a trade off between compactness of
the GPT and sensitivity to error in the lens separation.
ISC initial alignment (Smith, McInnes, Mason)
---------------------------------------------
Design for ISCT7 completed and reviewed;
procurements for ISCT7 assembly nearly completed (most
components already laid in, a few short-leads left to get).
Preparations for alignment of MMT3 are underway. Updates
to MMT3 optical lever assembly are on their way to Hanford to
address punch list developed by M. Zucker last week. The
laser autocollimator was returned to MIT for evaluation of
the theodolite mount. It looks like a revised assembly
procedure will take care of the problems found last week.
IOT7 components and documentation are in hand at Hanford
to complete Nergis' alignment verification and final
installation.
ISC controls (P. Fritschel, E. Daw)
------------------------------------
o More setup of the EPICS environment on our development system so
that
it now compiles and loads C code correctly
o Iterated on the layout of ISCT7, the reflection port table.
o Reviewed UFl's test plan for the Input Optics, and began working on
that
part of the plan involving the mode cleaner.

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 pieces for the reference cavity vibration isolation stacks have
been
delivered.
- The first article form fit heater jacket for the reference cavity
vacuum
chamber has arrived. The jacket fits snugly around the vacuum
chamber and
comes in two halves. Each half is fastened by Velcro. Each
heater has a
resistance of 50 ohms. The new heaters should provide a more
even heating
of the chamber than the heater used on the PSL in the Lauritsen lab.
- A 21.5 MHz rf photodetector has been completed for the LLO 4k IFO PSL.
- The LHO 2k IFO PSL was shutdown on Monday to facilitate a modification
to
the IOO/PSL optical table enclosure. The
PSL was operational for a period
of 39 days.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
Installation -
David Tanner is at LHO from the 27th til the 30th.
We have reglued the
magnet on the side of the mode cleaner curved
mirror. During this we
noticed that the magnets on the side of the mirrors
are strongly affected
by the fields from the magnets on the faces.
For example, it is not
possible to balance the side magnet on the mirror
(oriented on its edge,
with the face vertical). The fields from the
front magnets cause the
magnet/dumbell to fall over and fall off.
MMT2 has been measured to hav ea radius of curvature of 2.0985 m (spec
is
2.1000 m). MMT1 and MCCM are yet to be measured.
The Faraday rotator has been properly aligned and oriented.
The periscope height on the PSL table has been adjusted for proper
injection into the vacuum.
The beam tube connecting the PSL and HAM?7 has been installed.
Qi-Ze is coordinating with Sany and Malik in an effort to fine tune
the
mode matching to the mode cleaner. The beam profile after the EOMs
have
been measured at 150 mW and 7.2 W and Gaussian beam parameters obtained
show the expected thermal effects.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
2ITM01 has been measured and a brief survey of all of the 2KITMs has
been
completed. Our next objective is to show that good data can be
obtained on
a Folding Mirror at 0 degrees, where data are much more repeatable.
To
show this we will compare data taken at 45 degrees with data taken
at 0
degrees. We intend to ship a 2KITM and a FM to Hanford by February
8th.
Rai Weiss has been with us and shown two resonances
which effect our
measurement. One is vibrational at roughly
24Hz, the other is acoustic at
roughly 108Hz. We have acoustic, vibrational
ground and table spectra and
thermal gradient measurements which characterize
a "good" measurement day
in the Metrology lab, this gives us a figure
of merit for evaluating new
locations for the Metrology lab. A busy
machine shop is moving in beneath
the current lab within the next 3 months, we
anticipate the quality of data
to degrade significantly when this happens.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
(Helena is at the Hanford site, cleaning and suspending MMT3.)
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS
Mark B. and Mike S. completed measurements of the principal resonant
frequencies and Q's of the double cavity beam dump. The frequencies
lie
within the range 30 to 200 Hz as expected, and are acceptable. One
of the
lowest frequencies will be increased by strengthening the lateral walls
of
the beam dump. Craig C. is creating elevation and plan view layouts
of all
the cavity beam dumps in the BSC chambers, prior to completing the
drawings
of the horizontal and vertical mounting support structures.
PO TELESCOPE
All the parts for the PO telescope are being fabricated.
PO MIRROR
Modifications to the flexure design have been completed by Ken M. He
is
modifying the vertical support structure to avoid interference with
the
LOS structures on the SEI platforms.
BEAM STEERING MIRROR and PERISCOPE
All of the beam steering mirrors for the output beams of the PO telescopes
have been received, as well as the posts, mirror clamps, and bases
for the
periscopes. The mirror clamps are being modified to adapt to the standard
mirror holders.
VACUUM WINDOW
Experimental conflats and windows are being fabricated by Varian.
NEW CONICAL BAFFLE at MID STATION
Design is pending.
TRIPLE FLEXURE BRACKET for BEAM DUMP
Mike S. is studying the design requirements.
ELLIPTICAL BAFFLE/BEAM DUMP
A purchase order will be issued for production parts shortly.
IO BAFFLE, 2K
The parts for the IO baffle are scheduled to be baked and ready for
assembly on 2/1/99. Mike S., Betsy W., Jonathan K. , and Hugh Radkins
will
asemble and align the baffle during the week of 2/1/99. Paul
K. has almost
completed the released documentation package.
ITM BAFFLE
Angel and Mike S. have almost completed the redesign of the ITMx baffle.
A
modification is required for the ITMy baffle, because the baffle must
tilt
in the opposite direction.
INSTRUMENTATION BEAM
The ITM baffle and the ETM baffle have a 3.25 inch diameter hole which
will
provide a clear line of sight down the entire length of the 4K beam
tube.

Seismic Design (Mike Fine)
--------------------------------------
1. Electronics Rack:
The assembly of the rack hardware will be complete by the end of the
1st week
of February. Packaging modifications to the original design are being
made
to improve the layout and maintenance of the rack. In addition new
hardware
to remotely turn-on and off the amplifiers is being integrated into
the rack.
Two additional items not in the prototype are the cable connector panel
and
the multiplexing for three BSCs. These changes/additions have slowed
progress temporarily. Hytec will begin assembly of the second rack
shortly
after the first has been shipped.
2. Coarse Actuator Components
MSI told Hytec that the actuator components from Daedal (Coarse Actuators)
have a 4-6 week lead-time from last Monday. This is 2 to 3 weeks longer
than
earlier quotes. Hytec since asked for partial shipment and will
now receive
8 actuator sets on 2/19. They will then assemble the actuators onto
the scissor
tables and ship them to LHO on 2/23.
3. Near-Term SEI Hardware Delivery Schedule:
1 set of BSC in-vacuo hardware (Handord)

1. SUS Installation:
Helena Armandula and Mark Barton are cleaning the MMT3,2k and the RM,2k
at
Hanford. MMT3 has been sucessfully cleaned and Mark is starting to
rehang it.
(GHS note: This operation will have to be repeated
due to balancing problems (see LHO report)
They are using the traditional soaking-in-warm-Liquinox method of cleaning.
2. LOS Structure:
Brookfield has sent the reworked RM structure. It will be cleaned and
prepared
to go into oven on Friday night or Saturday morning. It can be at Hanford
on
next Thursday or Friday.

Detector Systems Engineering -- D. Shoemaker/D Coyne
(WBS 1.2.1.1.9)
---------------------------------------------------------
Global Diagnostics System (Daniel Sigg, John Zweizig)
------------------------------------------------------
John Zweizig
I continued to develop the software interfaces for algorithms to be
developed by the LSC and others, sketched useful data types, discussed
with Walid where defined data types are needed and how they should
be
implemented.
I continued discussion of the data types are needed for online analysis
and
how they should be implemented.
I started work on defining and implementing the trigger reporting software.
I have started to create trigger data classes that are in line with
the
database tables being designed by Xiao. These will be used in the monitor
programs to describe triggers and to send them to the Trigger Broker.
I am
also starting the design of the Trigger Broker.
Discussed hardware and software overlap with other GDS LDAS and CDS
group members.
An overview of the Data Monitor Tool project and a brief description
of its
current status are available on the web at:
http://www.ligo.caltech.edu/~jzweizig/DMT-Project.html.
I try to keep these as up-to-date as possible.
Daniel Sigg
Received the sine detection (i.e. swept sine analysis) routine from
Peter F.
Continued in writing the command line interface to the diagnostics.
Did the modules for controlling digital test points and using the arbitrary
waveform generator.
Integrated some 'old' driver code written by Mark P. which controls
a DS340 signal generator remotely into the arbitrary waveform generator/
command line interface to provide a common interface.
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. LHO: Most of the PEM equipment
is already shipped. This week
the PEM team tested the installation procedure
for the seismometers,
tiltmeters, interface plates with accelerometers
and PZT shakers. The PEM cart
DAQ was used. We performed studies on the tiltmeter
long time stability,
response of the seismometer and tiltmeters to
the ground noise, correlated
response of various combinations of signals from
two tiltmeters or
tiltmeter seismometer combination. The results
will be used for the final
installation configuration procedure. In particular,
the tiltmeters will
be mounted on polished granite plates.
Interface plates, accelerometers
and PZT shakers were mounted on
HAM 9. Again we performed studies on the performance
of the PZT shakers.
Preliminary results indicate that they are adequate
for the DC-200Hz
interval, as indicated by the manufacturer.
As we write this report, more
tests are in progress: correlation
between barometric pressure and tilts, the excitation
magnetic coils
performance.
3. LLO: the DAQ cart was assembled and now is tested
by Rizzi. Seismic
measurements are under way (Mark).
Optical Contamination (Daqun Li)
--------------------------------
One week data monitoring of air baked steel did not show an increase
in losses (either total loss or absorption loss). A few more weeks
is
needed to complete this testing.
The automation code rewritting last week for the Loss Scanner turned
out to shorten the scanning duration by a factor of 3 with a scanning
stepsize of 0.4 mm. With this achievement, scanning a large surface
area of core optics can be completed within a full day.
Enjoyed a first working day at the 40m lab by helping the 40m vent-
cleaning task currently being conducted at the 40m.
-----------------------------------------
Control and Data System -- R. Bork
(WBS 1.2.2)
-------------------------------------------
Data Acquistion System
======================
Hanford:
- Basic components are on hand to start up the system. About
1-2 weeks work
are needed to run the system on a near full time basis:
- Rack 2X3 (2k primary timing and suspension acq.)
is complete, but 2X5
(PEM/PSL/IO) rack still requires signal cable connections. Seismometer
and PSL
signal connects should be complete by end next week.
- Mid and end station VME acquisition units will
be assembled over the
course of the next 4-6 weeks.
- Due to the SUN PCI bus bug, we have to reorder
the data on the
reflected memory to meet the 16Hz update requirment on the frameBuilder
and
Network Data Server. This required a software change and a private
reflected
memory net to the Sun. The VME side of the software is complete, with
Sun side
to be completed early next week. Initial tests indicate this limits
total
system
thruput (from ADC readout to disk write) to 8MByte/sec/reflected memory
net.
- The GEO Triana and LIGO dataviewer and network
data server software
packages are installed and operational. The data conversion software
(allows
users to specify channels of interest and have them written to separate
files
with various formats) should be ready for first release late next week.
Livingston:
- Began equipment procurement process, with requisitions placed
this week
for:
- SUN450 server
- VME processors
- ADC modules
Equipment should start arriving in 4-6 weeks.
Control Area & Networking
=========================
Livingston:
- Fiber optics still being installed (est. two more weeks).
- PO placed for five Sun Ultra60 workstations to be used
as operator
consoles.
Input Optics
===================================
- 90% of the cables required for operation of the WA 2K IO controls
are
installed and terminated.
- Cross connect wiring for controls is 90% complete.
- Database records, state notation code and operator screens for control
of IO
components will be complete by 2/15.
- We will be testing IO controls functions starting 2/15 and should
be
ready for
locking of the mode cleaner starting 3/1.
Suspension
===================================
- Cable pull lists for 2K LVEA core optics suspensions have been sent
to
Hanford. Cables should be pulled and terminated by 2/15.
- System testing for these systems will begin 2/15.
- 7 LOS controllers and satellite amplifiers are being wired and tested
for
installation starting 2/15.
ASC and LSC Controls
==================================
- A test of the ASC front end and back end code has been scheduled
for
2/22. The
test will be conducted at Caltech.
PSL
======
1. Received the final version of the PSL frequency reference
cards.
Boards are in the process of being stuffed.
2. Final version 80 MHz VCO boards are in the layout stage and
will go to
the board house in several days.
3. Received the fabricated heaters for the PSL reference cavity
and they
work and look fine. They are completely removable by a velcro
fastening
system.
4. Reference cavity that was shipped to the east coast for fitting
of
insulation jacket will be shipped back on Friday 29 Jan.
5. Last board to be fabricated for the PSL is a frequency summing
board
for the summation of the PMC modulation sidebands into the FSS pockels
cell. This board will be fabricated in house on the mill.
MC LSC:
=============
Most of the LSC Mode Cleaner hardware is installed in 2X8 at Hanford
and
most of the cables are run. This should be completed during my next
trip
which will probably be the week of February 15th. The MC Servo Amp
should
be completed and tested and ready to install that week. I am building
some
RF amplifiers for the modulation drivers. Parts have been ordered for
the
RF and LO distribution.
Timing System:
=============
Two Timing boards are operational at Hanford. We have successfully
characterized the ICS 110B ADC boards so that we know how to talk to
synchronize them with GPS. We are now implementing the changes to the
design and will produce the final version as quickly as we can. It
should
be ready to test by the beginning of March. We are adding a Ramp Circuit
that is synchronized to the GPS 1PPS signal. By sampling the ramp output
at
16 KHz and extrapolating to " T ZERO " we can check the system
synchronization to a precision much better than a 16KHz period.

>From: Florence Kaufman <fkaufman@ligo.caltech.edu>
A modification was issued to the Apollo Sheet Metal contract to cover effort expended to support detector installation.
A modification was issued to Yakima Industries, exercising one of the
one-year options under which they will continue removing tumbleweeds from
the Hanford site.
PSI has submitted a list of equipment which they are offering for sale to LIGO. This is equipment remaining at the end of the vacuum equipment contract. This list is being circulated among the LIGO staff to see if anyone wants anything on the list.
Work has begun to search for designers and implementers for new signs to be erected in the front of both sites. It is hoped to establish a competition among three firms, with a committee selecting the best submittals for implementation.
GNB has indicated that they expect to submit their bid by the end of this week (this is for the hands-on gate valve disassmbly/reassembly and change out of the gate o-rings).
Continued to work with L. Turner, R. Torres and B. Kratochwill to get
all the available Hanford operational procedures on-line. Also, assisting
M. Zydowicz with mark up revision of the new Operations Safety Manual.
* Simulation
= Adlib multi mode implementation
"rec_sum", the module to be used for performing fast
simulation of LIGO is cleaned-up, wavefront characteristics
at various ports tested. New data type "clamp" that carries
mechanical information (position, pitch etc.) to mirrors has
been implemented in this module. Self-validation for single-mode
or multi-mode (but without swinging mirrors) and validations by
comparing with Twiddle are complete. The single-mode results
just matches with Twiddle outputs at all ports. Validation
with Ray Beausoleil's code for swinging mirrors is to be
started soon.
functions used by "lens" module have been rearranged in a
more software-efficient way.
The multi-mode version of the detector and telescope are being
contructed now. It will include the shotnoise effect.
documents are being rearranged and updated.
= Alfi GUI
Removed .prm and .xbm files from Alfi and moved them to Adlib and
AdlibMM
Release Alfi 3.1.13
Bugs Fixed:
1) Alfi no longer consumes enormous amounts
of cpu time when
performing minor tasks.
2) Bringing up the the popup menu from the
edit canvas no longer
causes a system crash.
3) When viewing the internals of a box, the
contents are immediately
displayed.
New Features:
1) Tool tips for boxes and ports now appear
above the box or port
they are describing.
2) To move all the components on the screen,
hold down the control
key and right mouse button
while dragging the mouse. Releasing the
mouse button will set the
placement of the components.
= e2e support outside of CIT
The binary programs of e2e have been copied to Livingston site
computer
and the computer environments are set so that the programs can
be used.
The latest version of the source code is copied to UFL.
= TAMA
Helped TAMA to use FFT. They expressed a possibility to send
a student
to Caltech for a week or so.
* LIGO Dana Analysis and Acquisition
= Lazzarini met with Bernard Schutz(GEO600) to discuss the possibility
of
sharing GEO data with LIGO as part of a reciprocity agreement
within the
LIGO-GEO MOU.
= Walid Majid
I defined a number of classes intended to be used for an algorithm
library. The definition consisted of identifying the data members
as
well as a number of useful methods or functions.
I compiled the latest release of ROOT v2.20/06 on our machines
and
installed an interface with Fcl and Vega packages. If
anyone is
interested in running ROOT with our framed data, I can help.
= Xiao Hu
XHU worked on frame database queries
XHU worked on GDS tables and queries
XHU worked on LDAS LOG tables
= David Farnham
DWF met with Kent Blackburn and Abert Lazzarini to discuss design
and
implementation of FrameCPP library.
DWF designed class heirarchy and public interface for FrameCPP library.
DWF met with John Zweizig to discuss library use and changes.
DWF continued coding for FrameCPP library. The library
is approx. 75%
complete.
= Philip Ehrens
PSE nearly finished the managerAPI.tcl
PSE is studying models of non-blocking I/O in Tcl to develop
and I/O
class for general use throughout the LDAS.
* Computing
= MIT:
Nothing to report.
= Livingston:
Received three Sun Ultra 10 CPUs and three monitors, but two of the
monitors
were damaged in shipment and have been returned.
= Hanford:
Installed the GC network into the LVEA X arm so the bakeout crew can
use
elog. The GC network is already installed on the LVEA Y arm.
The two
P5-90 PCs sent up from Caltech will be set-up in the LVEA for general
purpose use.
Started going over LDAS connections and layout with Larry W. along with
some of
the security procedures.
= CIT:
Barbara K. finished changes to the DCC web application for document
searching.
Added two more fields for both author and keyword searching to be used
in lieu
of the pull-down menus. The pull-downs aren't usable on unix
workstations
because they are too long. Reviewed changes to both web applications
with
Linda Turner and incorporated her suggestions. Help page for
searching
still needs to be updated. Then both applications are ready to
be
installed once Antares is ready. Antares is to be moved to D.
Beckett's
old workspace and then the software has to be reloaded to fix a problem
drive letters.
Wrote a query and form for DCC to use to repair the keyword table.
Also
devised a query for searching for 2 keywords assigned to the same document.
Began working on Y2K changes for DCC database.
Made several quick web site changes. Reviewed the sample web page
for the
as-built drawings with Fred Asiri and incorporated his suggestions.
Samantha has finished installing the scanner for GC usage. We now have
a scanner
and CD-burner that can be used by all on LIGO.
Working on the replacement of multiple pc's.
Suresh is working on the monthly full backups of the LIGO servers (sirius,
ligo,
gsparc, kater, spica). Resolved a number of PC related issues. Working
with the
rest of the group on the installation of the new Ultra 10 units that
have
finally arrived. One of the units will be replacing the old (acrux)
mail server.
Sean is still working some modem issues as well as working on the configuration
for using qmail to replace sendmail for mail services on acrux and
ligo.
A number of software issues are being worked on. Just as a note the
student
version of Mathematica is not valid for use by non-students and the
site
licenses of other packages we are using are good only for computers
on the main
campus of Caltech.
A number of computers have been relocated to accommodate staff changes
and
visitors. A number of new computer orders are in process to upgrade
obsolete
systems.
Dorothy Lloyd
Returned to work on Monday, Jan 25, after being away for five weeks, to an extremely heavy load of paperwork with problems needing to be resolved (new account codes, invoicing, purchase orders, funding supplements for contracts, etc.). Processed enormous stack of invoices and receivers for payment (see Cost Schedule Control Systems report submitted by Britt Leonhardt for further details). Continued to monitor and support the temporary help, who did a great job in my absence.
Rita Torres
For I. Petrac did change order No. 1 to SORL, Space Optics, change order No. 5 to General Optics, and letter to Hytec, Inc.
For E. Jasnow helped prepare IFB EJ-309 for Furnishing and Installation of BT Insulation at Livingston, FedExed 20 bound copies to be furnished to bidders by the site. For P. Lindquist reorganized reports in the binders in his office.
With W. Tyler and L. Turner, determined status of safety procedures. Coordinated with the DCC to obtain electronic versions, or have site deposit them there. Spent most of Wednesday updating the document list to reflect status, distributed list; obtained hard copies of documents missing from my office.
Distributed: PC289817 with ASCO Engineering, Inc., and PC290156 with Conejo Industries, Inc., also Distributed 84 sets of science articles to the science group.
Irene Baldon
PLEASE NOTE: As of today I have no backlog. All Expense Reports turned in have been completed and are in the hands of Travel Audit or out for signature and/or signature approval. My backlog remains ZERO.
Worked on the paper work for various new trips taken recently (7 Purchase Requisitions and 9 Advance Requests). There are 12 additional new trips pending completion of travel arrangements. Completed 13 Expense Reports, some of these were still not taped or completed by the Traveler. As a result of the push a couple of weeks ago to clear my backlog, I have had extensive recording and filing to do this week.
Prepared Travel/Vacation Itinerary for the Week of January 25th, 1999.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as for members of the staffs of each of the two (2) sites.
Elizabeth K. Wood
A reminder: If the information about you in the new Caltech phone book is incorrect or if you want any changes, please let me know.
Kept in contact with the phone office to find out about moving phones. The phone office has been in disarray due to moving themselves from one building to another. I don’t have an exact date yet when various phone will be moved; I’ll keep the affected parties notified.
I talked with Lee Stevens and sent a memo to Tom Schmitt at HR concerning Caltech paid vacation time for state holidays. This was prompted by Mark’s question about getting Mardi Gras off in Louisiana. Here is Lee Stevens’s answer:
"We don't give off state holidays... here in California, Hawaii, Washington or Louisiana. ...they would need to take their personal holiday or a vacation day. ...we need to be consistent with all our staff- regardless of where they are based."
Dealt with a variety of personnel issues among them clarifying retirement benefits. Also looked into new ways of doing the same things. Still working on it.
