The Project Control Meeting
Agenda for Monday August 16, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #50, consisting of 4 LOS structures, BSC
leg
elements and misc. Beam Dump and Baffle parts, was released Tuesday,
8-10-99.
Load #51, consisting of the 2k Beam Splitter Optic is being rebaked
and
should be released tomorrow, 8-13-99.
I have begun preparing Vacuum Bake Oven B for preliminary pump down
and
leak testing.
I have, as yet, been unable to sit down and itemize all of my specific
concerns regarding the shortcomings of the traveler system (as practiced)
but hope to have some time to dedicate for this purpose soon.
Optics:
---------------------
(D. Cook)
During the final steps of the BS-2k installation
last week we had a
sudden motion of the optic which cause two of
the magnets to break off
even with the chamfer stops set close. One of
the BS the chamfer stop
viton tips are longer and more flexible than
for the other core optics
and need to be gapped closer. This may have prevented
the damage to the
magnets, but I should have had the optic clamped
by all of the stops at
this point. A sudden unexpected motion occurred
when I lowered the
installation fixtures, releasing the restraint
and any support under the
LOS. This motion was due to the CG of the optics
table being off with
the LOS clamped in place. We had moved the LOS
location during the
alignment, a relatively long distance, in relation
to its starting point. The table now off balance the LOS made a jerking
motion when released. The precision spirit
level that I was using to periodically check
the level of the table during the alignment was also out of calibration.
Readings varied depending on the orientation of the
level. Excuses!, excuses!, excuses!
The future default will be to always have all
the safety stops secured
against the optic even while making seemingly
small moves. This will
include doing any mounting of items to the optics
table that could
jostle the LOS. I will update the installation
written procedure to
include these precautions and steps.
The BS-2k was reprocessed and is currently in the vacuum bake oven
and
is due to come out late Friday. It will be cleaned, re hung and
confirmed and hopefully reinstalled on Monday. The alignment late Monday
or early Tuesday.
With help and ideas from D. Shoemaker, H. Rong, H. Radkins and M. Barton
we checked the percent of reflectivity from the ETMy, ITMx, FMx using
the laser autocollimator (670nm) to help Ken Mason determine whether
we
need to re-think parts of the alignment process. The power level is
being checked normal to the optic, at 1 to 6 degrees incident and at
45
degrees focusing the beam down to the aperture size of the power meter
with no ambient light present. I am also retro-reflecting from an
optical flat and/or a corner cube with a single bounce to see if the
laser autocollimator power meter can detect the returning signal. The
basic results are:
Total Laser Power Output= .31mw
1/ SP-ETM-03-A
laser autocollimator angle = 0 deg.; reflectivity
= 7%
laser autocollimator angle = 3 deg.; reflectivity
= 6 1/2% (.02 mw)
laser autocollimator angle = 45 deg.; reflectivity
= 3 1/4% (.01mw
2/ 2-ITM-04-06
laser autocollimator angle = 0 deg.; reflectivity
= 19%
laser autocollimator angle = 1 deg.; reflectivity
= 31 1/2%(6mw)
laser autocollimator angle = 45 deg.; reflectivity
= 9 1/2% (3mw)
3/ FM-02-A
laser autocollimator angle = 0 deg.; reflectivity
= 3%
laser autocollimator angle = 1 deg.; reflectivity
=
laser autocollimator angle = 45 deg.; reflectivity
= 3% (.01mw)
NOTE: none of the optics had a signal strong enough
to retro-reflect
back to the autocollimator
These three optics are staged and waiting their installation.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC5 X-Mid 2K ETMx:
The external hardware installation is completed and we broke vacuum
on
8-10. Currently the Support Tubes are staged on the Roller System
ready
for insertion. That should happen 8-12 followed by the door removal
and
the Downtube Assembly going in, hopefully the same day. By the
end of
the week, the bellows should be in place followed by the V-Blocks
comnnecting the internal components to the external support.
Coarse Actuation System (CAS) Rack:
Mark Guenther has one last wiring fault to ammend and the first BSC
CAS
system should be operational for BSC4. We still are awaiting
cabling for
three more BSCs that will require check out; the other ports of the
multiplexed rack may too need some work. We expect to get the
cabling at
LHO for BSC7 (2K ITMx & FMx) soon.
X-Fine Actuation System:
LHO has received the first PZTs and controllers that will be adjusting
arm length in reponse to diurnal gravity effects and ITM/ETM differential
ground motion. These will provide ±90 microns of motion
at the ETM.
This system been tested at HYTEC Inc. but still needs to be interfaced
with the IFO.
Computing:
----------
(C. Patton)
With Dave Barker's help, the General Computing network has been set
up
in the VEA of the Y Mid Station. A 3 port hub has been mounted
near the
cryopump support beam, right under the phone and the oxygen monitor,
and
next to the power outlet. Mark Lubinski was able to get cables
run to
the Y Mid PEM RGA computer and to get that computer on the GC network.
Conducted a test on rainier to confirm that it is possible to have
software licenses served across multiple networks. This is in
preparation for getting a Sun Workstation to act as the license server
for GC, CDS, GDS, and LDAS networks. This will provide one place
for
all application licenses, like Matlab, Mathematica, Compilers, etc.
Having them all in one place will help with conformity issues and with
administering software licenses and installs.
I am still working on trying to get a service contract for the CDS and
GC ATM equipment.
Did the usual backups, added more user accounts, ordered more supplies,
and kept the GC accounting paper work up to date.
Electrical & Electronics Systems:
---------------------------------
(R. McCarthy)
Work continued on the 50kHz signal associated with the suspension coils.
Josh saved scope traces of the signal after installation of various
fixes. The first fix was the installation of a .1mic F cap. This
eliminated the 50kHz and we have since been making minor modifications
trying to fine tune the system. Though it would appear that Jay's
first
idea was the winner.
Continued to work on the LN2 control valves. After working with
John W.
last week on the Left Mid station I decided to check on all of the
valves. To my surprise I have found a need to adjust the others.
This
will continue as time permits.
As part of general facility work, much of the week has been spent in
maintenance activities. Fixing lights and general checks of electrical
systems.
Physics Environmental Monitoring:
---------------------------------
(M. Lubinski)
PEM cable and equipment installation continues at Hanford. We
are
currently installing finishing the cable installation in both X and
mid. We also set up the RGA at Y mid for remote operation via a software
program
called Laplink through the network. So far this has worked very
well
and we are able to run the RGA and transfer files from a remote computer
all in
real time.
Detector installation: BSC#2; All Scissor Tables, Dummys, Air-Bearings and Course Actuators have been installed. Cross Beams will be installed by end of this week. (Rich Riesen)
Elecrical installation: Installed power supplies and crates at both end stations. Generated list of boards and other equipment required to finish building up the racks in the end stations. I have asked Rolf and Jay to go ahead and send me the drawings and parts (or parts list) required for the cross-connect panels so that we can build them here rather than wait for them to be built, tested and shipped from Pasadena. Installed a variety of cables between the Mass Storage Room and the LVEA. A few are for immediate use. The rest are for when they change their mind. Made some test cables for Sany to help him with SOS test stand. Relocated the weather shtuff to their permanent home. Some cabling nightmares need to be resolved by Anthony. Continued the work on the suspension racks in the LVEA.
Prepared and set up cables between MSR and LVEA. Ordered and received
electronics components for CDS installation
work. Updated the section of drawings at CDS LLO web page. (Wooley,
Svoboda)
Beam tube bakeout: Progress on BT bake has been good this week. All data collection and pumps continue to operate normally. We did have two separate power failures the last week which resulted in pump shut down. The first was Mon @ 1730 hrs and was due to a thunder storm, the second was on Wed also at 1730 hrs, when we lost a 100 amp fuse at the mid station. We will check our power draw at this location to see if we need more current. Both failures did not do any damage and all systems restarted without problem. The bake weather station is now operational. Our radio communication system is up. The vertex is pumped to 2E-5 and has stopped. An RGA scan indicates high H2O pressure (10X H2 pressure) but we also feel we have a leak and are in the process of locating it.
Weather Station: 7 day test successfully completed with no lockup's.
Medm screen changed over to scalable fonts and further c-code clean up
completed. Location of weather station ioc changed due to change in direction
from CDS group. The move was accomplished and wires were organized and
connectors put in housings.
CDS Printers and aliases installed on london to allow printing
of documents on london to GC machines.
GRASP Transfer function of from shaker amplifier input to seismometer
output was measured. Transfer function from Mathematica formula to speaker
output was also measured. Transfer function from Mathematica formula thru
shaker amp and shaker to seismometer amp. also measured as a check. Problem
with not recognizing chirps injected strait into dcu adc is mostly understood.
Optimalf is in the process of being diagramed and changed. Seismic measurements
at end station to begin soon; noise issues are being understood. (some
ground loop problem)
Optics and suspensions: Prepared the SOS test stand for operation
test. Made all cables needed to use a satellite module. Checked the IOO
inventory. We have all the parts except wire standoffs and wire guide rods.
The wire standoffs and guide rods are supposed to have been shipped to
LLO in May from Univ. Florida. Need to find them out. Ordered a microscope
we need to check optics and other small parts for IOO components. Measured
the radius of curvature of two MMT3s. The two pieces showed R=25.09 m and
25.12 m, respectively. (designed value = 25.16 m).

Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
Interferometer Sensing & Control (P Fritschel for M Zucker)
===========================================================
We continue to work toward preparations for the LHO single
2km long arm cavity, with testing planned to begin at the
end of September. Nearly all the components for the ISC sensing
tables are on hand, and they will be built up at LHO over the
next few weeks. The ASC electronics rack is in the process
of being built up at LHO, and we plan on installing some
additional software - the ASC supervisory/user interface, and
controls for the WFS picomotors - in the last 2 weeks of August.
The LSC electronics design & construction is moving along,
with Rich A and Mohana being enlisted to work with Dale.
o IAS Initial Alignment /ISC Design (K.Mason, M.MacInnis, M.Smith)
ISC tables WISCT-9 and WISCT-10 were shipped Monday for Hanford. They
were shipped in three skidded crates and are scheduled to arrive on
Friday.
Riser blocks for all ISC tables were delivered and will be shipped
today. Connectors which run from the chamber viewports to the
ISC
enclosure have not been delivered yet.
The Initial Alignment Procedures T970151-B4 has been updated with new
methods found in aligning optics in the LVEA and includes reversing
the
ETMx and ETMy alignment to hit the HR surfaces directly.
Parts of the ETM transmission monitor assembly had come in. I
started
the assembly with Myron, who noticed we had an incorrect size lens
holder. I bought the right size lens holder and had Ed Kruzel make
a new
riser block to offset the change in height. I will need to rebuy
the
balance of the holders and riser blocks. I also had a minor
interference problem with the mounting plate for the Quod diode
assembly. I reworked the parts so that they now fit fine.
I am still
waiting the parts to hold the camera in place.
I (M.Smith) sent Jay Heefner the boxes and parts for the quad diode
assembly for the ETM transmission monitor.
I will place an order for the balance of the optics for the ETM
transmission assembly. We only bought one set of optics at first.
I also sent Jay the assembly parts for the wavefront sensors.
He will
have enough parts to make 8 WFS assemblies. I need to place an
order
for the remaining parts. We had canobolized the parts from this
assembly to make ETM Quad diode assemblies.

Prestabilized Laser -- Peter King
--------------------------------------------
- 10-W laser SN #109, with the current shunt actuator, has been
shipped to LLO. The laser should arrive sometime today (08/12).
Apparently the crate containing the laser weighed too much for
the cargo plane that flies between New Orleans and Baton Rouge.
The weight of the crate was 238 lbs.
- Two new pre-modecleaners have been constructed.

fluctuations on the PSL table
LLO:
- Prepared the SOS test stand for operation test. Made all cables needed
to use a satellite module.
- Checked the IOO inventory. We have all the parts except wire
standoffs and wire guide rods.
- Ordered a microscope we need to check optics and other small parts
for
IOO components.
- Measured the radius of curvature of two MMT3s. The two pieces showed
R=25.09 m and 25.12 m, respectively. (designed value = 25.16 m).
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
We have completed measurements on SPETM06 and will be transferring it
to
the OTF today.
Various cleanup issues are being addressed with Veeco. We have
received
some software updates and we have sent back test flats E and F for
re-bonding. Some minor software bugs are still being addressed.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
Most of the week was dedicated to tie possible loose ends pertinent
to the
future operations in Livingston. Finalized a number of procedures,
ordered
some tools and materials.
Core Optics Support -- Michael Smith

Mike S., Ken M. visited the shop of the lowest bidder to evaluate their
capabilities. A contract for 12 telescopes will be let the week of
8/16.
ETM TELESCOPE
Mike S. and Ken M. revised the layout of the ETM telescope steering
mirror
to bring the output beam to the inside of the y-arm at BSC6, and sent
a
drawing to Ken Mason. The ETM vacuum window beam dump was also located
on
BSC6 optical table. An alignment aperture for the ETM telescope alignment
was located on BSC6, and the alignment aperture has been fabricated.

Seismic Design (Mike Fine)
--------------------------------------
1. Electronics Rack:
The updated version of the CAS software has been delivered to LHO.
Hytec is finishing checkout of LHO Mobil Rack (Rack #3). They will
then need to finish going through some motion-related tests. These
will be completed prior to shipping tomorrow. Hytec received the
prepped junction boxes from Hand Precision and will be contacting
ETS in Albuquerque about finishing the assembly of these boxes.
Hytec has begun the assembly of rack #4. Wiring the side panel is
continuing, which is scheduled to be completed by 8/20/99.
2. CAS Documentation:
Hytec will begin the final documentation for the CAS electronics. They
have not had the opportunity to fully document the hardware due to
manpower being focused on the actual build and delivery of the racks.
There will be two revisions, the original issue (what have been
delivered for Rack 1) and the Revision A which will include all
the changes that have been made since the delivery of Rack 1.

Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. Report from Janeen:
-Working on LLO suspension preparation.
-Coordinated with LHO personnel on BS magnet mishap and
re-gluing.
-Fabrication of the beam dump metal parts started last
friday, with a two week estimated delivery time.

Detector Systems Engineering -- D. Shoemaker/D Coyne
(WBS 1.2.1.1.9)
---------------------------------------------------------
Global Diagnostics System
(Daniel Sigg, John Zweizig)
I have release the new distribution of the DMT Root software
(rdist-0.2) containing the linux compatible sources and numerous
other improvements. The new distribution is available through the web
-
for details, see http://www.ligo.caltech.edu/~jzweizig/DMT-Project.html
In addition I continued to improve the online documentation, added
new error reporting features to several programs and have resumed
working on the trigger logging software.
I also performed several system management functions for the
DMT machine at LHO such as creating and modifying accounts
and installing scripts to make sure that important functions are
restarted after a reboot or failure.
Continued with testing the performance of the gigabit ethernet. The
gigabit ethernet connects the DMT (SUN 450) with its own frame
builder (Ultra 10). Speeds of up to 320Mbps were observed.
Wrote a first version of a broadcast interface API which will allow
the frame builder to broadcast frames over UDP/IP to several clients.
This in effect will allow the DMT frame builder to send a full frame
including testpoint information (about 12MB/s at LHO) once to all
interested parties.
Physics Environmental Monitor (Matt Smith, David Shoemaker)
-----------------------------------------------------------
the status for PEM delivery can be found at
http://web.mit.edu/marin/www/August99.html
Updated the drawing for the PEM sensors locations at Hanford and
supplied it to Mark Lubinski. Talked with Mark L., Richard M.
and Dave
B. on the next PEM cableing that can be started. David has initiated
a
meeting for prioritzing PEM cabling at Hanford. People have suggested
that PEM supply a barometric pressure sensor for inside the LVEA.
I
amloking into buying another Davis weather station.
It was also discussed if we actually need a particle counter connected
to the CDS backbone in the mid and end stations that was allocated
to
the "Optics Room". It was suggested that for now, a portable
particle
counter be used and not necessarily hook one up permanaly.
The Q422 software for the RGAs is on order and should be delivered to
Hanford by the middle of next week.
-----------------------------------------
Control and Data System -- R. Bork
(WBS 1.2.2)
-------------------------------------------
Data Acquisition (Rolf/Alex/Hongyu)
===================================
- Fixes to log scale displays in dataviewer should be complete later
today.
- Switch over of Framebuilder code from use of the VIRGO Frame library
to the
LIGO Frame C++ library is almost complete; first tests to be run on
the 40m
system later today. If all goes well, will install at Hanford next
week.
- Sigg's network broadcast class library incorporated into the network
data
server; ran some initial tests using a server and several clients.
This, along
with other mods made this week in the DAQ controller and Framebuilder
code,
should allow us to broadcast framed data to the GDS Data Monitoring
Tool via
gigabit ethernet. Installation and first tests at Hanford is planned
for next
week.
- Code on the 40m prototype system has been modified to accept the
LIGO timing
modules. Installation and test of hardware/software is planned for
later today.
LSC/ASC (Rolf)
==============
- Pentium III processor boards and PMC based reflected memory boards
arrived
this week. Unfortunately, the vendor forgot to load vxWorks board support
kernel
into the processor board flash memory, and the processors had to be
sent
back.
Vendor will load software and ship units direct to Hanford to arrive
by Monday.
- Video switch system arrived. This is the last component necessary
to install
the video system at Hanford. Barker and I will install this while I
am up
there
the next two weeks.
Suspension (Jay)
==================================
- Completed testing of LOS controller for WA 2K ETMY and ETMX. The
chassis
will
be shipped this week.
- Discovered that the 50KHz noise on the IO suspension controllers
is probably
due to an interaction between the coil and the transimission line formed
by
the
cable from the controller to the coil. The result has been confirmed
with
modelling and field tests. We are in the process of determining the
best
fix to
implement.
- TNI suspension controller prototype boards have been stuffed and
are being
tested. Tests should be complete by the end of next week.
ASC (Jay)
==================================

- Front panels for the the modules listed above have been designed
and an
order
has been placed. The delay caused by the new procurement system will
mean that
the modules will have to be installed for the first system tests without
front
panels. The panels will be installed when they arrive.
EO Shutter Controller (Sander)
==============================
High Voltage fault prevention daughter boards and
new front panels were on
order. Expected delivery ~ 3 weeks.
DAQ Antialiasing Filters (Sander)
=================================
Two (2) each of the BNC and LEMO boards are in various
stage of
completion.
Delivery of the units to the sites can be make within a week after
receiving the
filter modules and front panels from the vendors ( ~3 to 4 weeks).
2K One-Arm Test CDS: (DAO)
========================
The Demodulator board is designed and the PCB has been layed out. We
are
sending it out for fabrication. The Servo Filter board is still in
the
design phase. Jay is assisting Mohana while I finish the Timing System
components. Three LSC photodiodes are 90% assembled. I need to select
the
tuning components, test the first one and then we can finish the others
in
our shop. The wiring diagrams, EPICS screens and data base records
still
need to be done. But these are fairly simple for the one-arm test and
should not take long.
Timing System CDS: (DAO)
=====================
GPS Clock Driver number 8 is up and running. This one is configured
to
clock an ICS-110A and will be installed in the 40 meter today. Two
more
clock drivers will be complete and tested by tomorrow. These will be
shipped
to Hanford. The final version of this board is in PCB layout and should
be
done next week. We should have a first article tested in one month.
We have
10 ICS Clock Fanout boards fabricated. We will begin assembling them
in the
shop today.

From: Syd Meshkov <syd@ligo.caltech.edu>
The Visitors Program Proposal to NSF was submitted last Friday. However,
we had to jump through a series of FastLane hoops this week, before
it was
finally transmitted by OSR and accepted by NSF. There is now an official
ID# 9986274, so we should finally be done.
I wrote an article for the LIGO Newsletter describing the Amaldi
Conference. This has been transmitted to Dave Beckett and should appear
soon.
I participated in the August 10 meeting of the General Members of the
Aspen Center for Physics. As Chairman of the Winter Conference Committee,
I gave a report on the 1999 conferences, mentioning The Gravitational
Wave
meeting at Moriond. I also presented the plans for the year 2000, which
include the Conference on Gravitational Waves and Their Detection,
to be
held Feb. 20 - 26, 2000. The plan is to have this conference emphasize
Advanced Detector R&D, just as GWDAW emphasizes Data Analysis,
with
a
very interactive format.

TECHNICAL CONFIGURATION MANAGEMENT
(Althouse)
Michell, Sam, Biplab and Hiro worked on the validation and performance
study of LIGO using e2e.
Michell focused on the triangle cavity. Hiro calculated the transmittance
of various modes through pmc in PSL in the PSL model
developed by Rick, Biplab and Hiro.
Sam worked on the full LIGO core optics configuration and for the FP
configuration expected soon. Hiro calculated the coupling
of the mirror rotation to the length signal.
Based on their results, Biplab worked to fix some problems of the program.
PSL model
Biplab worked to resolve the discrepancy between e2e and Sergei's implementation of tri mirror cavities.
adlib field implementation
Bill Kells, Matt and Hiro spent long time in discussing the proper implementation of the modal model in adlib.

(1) Developing Visualization and GUI control panel for user interfcace to LDAS (~75% done).
(2) Data Filters: The first one that I am working on is Matlab: so you
can do this:
ligolw2matlab < sample.xml
> sample.mat; matlab sample.mat
which will bring up a matlab session with the content of the LIGO_LW
file This is ~50% done.
Hanford:
With Dave Barker's help, the General Computing network has been setup
in
the VEA of the Y Mid Station. A 3 port hub has been mounted near
the
cryopump support beam, right under the phone and the oxygen monitor,
and
next to the power outlet. Mark Lubinski was able to get cables
run to
the Y Mid PEM RGA computer and to get that computer on the GC network.
Conducted a test on rainier to confirm that it is possible to have
software licenses served across multiple networks. This is in
preparation for getting a Sun Workstation to act as the license server
for GC, CDS, GDS, and LDAS networks. This will provide one place
for
all application licenses, like Matlab, Mathematica, Compilers, etc.
Having them all in one place will help with conformity issues and with
administering software licenses and installs.
I am still working on trying to get a service contract for the CDS and
GC ATM equipment.
Did the usual backups, added more user accounts, ordered more supplies,
and kept the GC accounting paper work up to date.
Livingston:
More investigation going on related to the fiber installation for future
connectivity.
There is to be a teleconference with BellSouth concerning this issue,
Friday the
13th.
CIT:
Samantha is reworking the Y2k issue on the pc's, went through 40m and
laursten
almost, at the same time also updating the web based ip list.
Discovered a problem with one of the patches. It has caused one computer
to fail
and another to have problems, will watch closely further computers
to see
if they to have problems. If so will try to find a work around
Helena's computer had a virius took care of it, but be on the lookout
for
a document virius
Set up Jim's gateway after picking it up, it seems to still have issues
Fred Mann's computer crashed after installing patches on it.
The crash
has been coming for some time though. He is having to reload
all of his
software.
Scanner is set up and working wonderfully on the desk behind my computer
Cd burner is still working and not crashing as frequently.
Barbara installed the public version of the DCC
web searching tool on the LIGO
web site.
Made more changes to DCC database for Y2K. Added sort fields
for Docno
and Year. Had to work through stokesware to figure out how to generate
the
sort fields automatically during the various data entry processes.
Am in
the process of incorporating the sort fields into the DCC web tools.
Took 3 days of vacation.
Ed Maros upgraded maasim and propus to Solaris 7
Researched laptops for Linux.
Upgraded a Toshiba 710CDT laptop with a 3.1 GB hard drive and installed
Linux
and Windows 98.
Suresh has finished up the backups for the month and is working on backup
s/w
for the tape robot. So far the tape robot from Qualstar has been much
more
difficult to setup and is not as reliable as the tape robot from Exabyte.
We have finished another phase in getting the LIGO network connected
directly to
CITNet2000 (The new backbone for Caltech). Presently, everything appears
to be
working well and we will be disconnecting more of the old routes after
hours,
one at a time, before the transition is complete. There may be some
glitches
because of gateway/routing setups on machines and information related
to that
will be sent out.
Working a number of procurement issues and trying to get things backup
to date.
The VPN setup has been very dynamic and will be for a few more weeks.
LIGO was
one of the first groups to start using it and it the VPN still has
some
logistical problems. Fred Raab has been working with the 486 version
and has
found a number of issues with trying to connect to the library. So
far, the VPN
has been working with the APE Oracle project with minor issues.
The demand for laptops to be used for travel has increased lately,
all of the
old refurbished ones are presently in use. We will try and add a few
more units
to the pool.
Irene Baldon
Worked on preparing the paper work for 13 new trips taken recently (13 Purchase Requisitions and 7 Advance Requests). There are approximately an additional 11 new trips in various stages pending completion of travel arrangements before the paper work can be completed.
Completed 36 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. There is a considerable number of Expense Reports still to be done.
I continue to push for both Advance and Expense Checks already submitted. The "System" is extremely slow in processing these. Performed normal recording and filing associated with Travel and Reimbursement.
Attended yet another ORACLE meeting and had additional discussions with various ORACLE personnel. Travel has yet to be worked out and things are in a state of confusion. It is very difficult to get things through or out of the system.
Prepared Travel/Vacation Itinerary for the Week of August 9th, 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. I continued to do MIT's travel to the sites for installation activities.
Rita Torres
For I. Petrac did letter to University of Colorado to send the signed original MOUs for their files. Formatted Attachments A and Z to MOU with the CIT Relativity Group. Did letter to Moscow State University to transmit MOU Attachment Ds for previous years.
Spent most of the week trying to submit the new Visitor Proposal to NSF via the Fastlane website. Coordinated much with Sponsored Research and S. Meshkov to assure all required pieces were present for the proposal. The document was finally submitted to NSF late afternoon on 8/11/99.
Coordinated with the national pagers company to return a malfunctioning unit. Also coordinated with the local pagers company to trade units that do not work for units that do.

Dorothy Lloyd
Continued to process invoices for payment and enter new requisitions. Tracked and followed up on various invoice problems, and signed off and closed out a number of POs and receivers. Continue to reconcile status reports.
Elizabeth K. Wood
It must be that time of the year: I spent the vast majority of my time working on personnel actions.
In between phone calls, I managed to prepare a petty cash reimbursement package. We’ll see how long it takes this time to get the petty cash reserve re-funded.
Attended a PMA meeting to discuss the use of WEBSTER. Alan Rice gave
a very enlightened discussion of the uses for WEBSTER. If only WEBSTER
had been working that morning, we could have been even more enlightened.
In any case, it is clear that he is sympathetic to the plight of PMA and
the institute as a whole.
