Weekly
Report Highlights
Livingston Ham1 and HAM4 are receiving seismic isolation
support tables and beams
LLO logo coffee cups now available for purchase
through LLO and Caltech Project Office
Facilities:
-----------
O. Matherny
Water System modification
The control problems are fixed, all functions
except the
irrigation was exercised. The irrigation will
be tried out
next week, and the contract can be closed.
New staging Building
The contractor is off the site until the steel structure arrives.
Expected first of April.
Compressors
Levernier and Apollo are trying to get Kaeser and their
representative, Electric Air and Pump, to honor the
guarantee. Even if we decide to change the air
compressors the ancillary equipment should be as
Kaeser recommended.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #21 consisting of two LOS structures (s/ns
D970551-002,
-003) was released earlier this week.
LHO Vacuum Bake Oven A load #22 consisting of three BSC support tube
bellows (s/ns 008,
010 and 013), two SS weights and one view port is presently in the
middle of its vacuum bake.
Load #23 should start 3-29 and will consists of ?.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
Received covers for the Air Bearings this week. Will begin installing
for all four chambers which
have naked Air Bearings.
HAM work
nothing to report
BSC8 work
In-vacuum hardware installation was completed
on Friday. After the alignment problems due to
badly machined holes in the Support Table, we found that the alignment
of the Leg Elements
afterward was far better--Leg Elements were obviously machined more
desirably. Once the stacks
were built up, the Down Tube was rotated and set down on the stacks.
Measurements were taken
to check the "centered-ness" of the Down Tube w.r.t. the Support Table--range
was very small
showing that the problems we had with the bad holes didn't carry up
to the Down Tube((Hugh's in
situ machine work was a success)). The cables were installed.
500 lbs of payload were distributed
on Optics Table according to layout plan supplied by D. Coyne.
A check of the level of the Optics
Table was also taken (note: no vertical adjustments can be made
until the Scissors Tables are
connected to the soon-to-be-arriving electronics racks). The
Table looked really level (within a
mm), the elevation may need to be changed however.
Finally, the dome and doors were re-installed
on the chamber. Currently, the left beam manifold is
being pumped down.
PreStabilized Laser:
--------------------
(Rick Savage)
Power measurements made last week with a recently
purchased (and calibrated) power meter
reveal that the power meter that has been used
to measure the PSL output power is not accurate
and that the PSL power is about 0.8 watts lower
than previously reported (7.2 W rather than 8.0
W). This was verified by a third power meter
that was purchased for the PSL effort as a calibration
standard and by checking the meter calibrations
by an electrical substitution method.
An attempt was made to increase the 10-W Laser
output power by increasing the current to the
amplifier pump diodes. The current had
already been increased to 24.65 amps from the original
setting of 23.15 amps. The output power
no longer increased significantly with amplifier current at
25.6 amps. The maximum stabilized output
power is thus 7.2 W. A new 30-W power meter will
arrive today and will allow us to measure the
output at the laser head.
The PSL shut down unexpectedly due to a fault
in the power supply to the 10-W laser. We
suspect that the circuitry that protects the diode lasers from current
spikes may have triggered the
shutdown. We have asked Peter King to question Frank Adams of
Lightwave regarding means of
avoiding this type of failure. This has occurred approximately
six times during the past four months.
We are investigating making a temporary connection of some of the PSL
fast channels to the data
acquisition system.
All non-essential equipment (including the large tool box) has been
moved out of the laser area
enclosure in order to limit unnecessary access.
A new general computing Sparc station was set up (with help from D.
Barker and C. Patton) in the
computer users room in anticipation of B. Bhawal's visit next week
to work on the end to end
model for the PSL. With help from H. Yamamoto, the e2e software is
now running again at LHO.
Contamination Control:
----------------------------------------
(C. Gray, K. Ryan, R. Savage, B. Weaver)
Samples of a black substance wiped from the down tube in BSC8 was sent
by B. Weaver to Seal
Labs. for analysis. We expect it is just aluminum oxide, but
want to make sure.
F. Henderson, the Kennewick High School student who has been monitoring
particulate levels in
our labs gave a sack lunch seminar today on his work. He will
start working on a writeup of what
he has done. He expects to finish the writeup by May 1.
Laser Safety & Optics:
----------------------
(D. Cook)
Hopefully we will have finished the LOS installation tooling
modifications, cleaning and reassembly done by the end of the week.
We have
the new 6'x10' soft wall enclosure staged in the LVEA. I have worked
with
Helena and the CO2 "snow gun" in the optics lab on one of the ITM,s.
So
far, its does a much better job of removing dust particles than the
ionizing
N2 gun. It had some effect on removing residue, caused by drag wiping
areas
of the optic prior to baking. The drag wiping was to touch up
areas after
replacing a magnet which had come off. We will be using the "snow gun"
Thursday and Friday to clean the in-situ optics in HAM 7, after the
OSEM
rework is completed. The RM mirror in HAM 8 will be cleaned and it,s
alignment checked after the OSEMs are replaced. We will be staging
for BSC
8 Installation for the ITM and FM. The next ITM and FM are being processed
in the optics lab.
Core Optics Support:
--------------------
(B. Weaver)
No report received.
Computing Systems:
------------------
(C. Patton)
The Livingston Communication router for the modem pool is on the network
and accessible from my PC. A modem has been connected to it.
However,
the modem is not talking to the Livingston box and although the
Livingston box recognizes that it has a modem plugged into it, it is
not
talking to the modem. I'm still working on trying to get them
talking
to each other.
All guest Sun workstations are now running the Solaris 7 operating
system, the current Y2K compatible release from Sun. The server
is
still running Solaris 2.6 and will have patches installed to make it
Y2K
compatible.
The Sun Workshop compilers, upgrade and additional license, have arrived
and will be installed on the server this week.
Electronics/Electrical Systems:
-------------------------------
(R. McCarthy)
The cables for PEM microphones on the 2k arm have been pulled in but
not
terminated. Terminations should start 3/26/98.
Power circuits were run for all the ISC tables. There is a receptacle
on a
whip under the cable trays that can be pulled out when the tables are
in
place. This is CDS power and should not be used for anything
other than
isolated CDS equipment.
Installed safety screen on the crane lights. The bulb could break
free and
strike some unsuspecting soul on the head.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
The Turbos and Cryopumps have been installed and leak checked at X2-1
and
9. We are currently pumping on X2 module. The data system
has been
installed on X2 and running. All power has been removed
from X1 by the
local Public Utility District and Sun River has removed all the 45
KVA
transformers from X1. The Calibration cart and aux turbo have
been
installed at X2-5 for the RGA.
Vacuum equipment (Allen Sibley): PSI has accepted responsibility
for the leaking gate seal on GV-1 & 2. These valves will be repaired
by GNB. We hope to do this work when GNB is on site to replace the mid
point valve O-ring with new fluorel material. As
of now this doesn't appear to hamper the detector installation work.
Leak checks can be preformed by pumping out the adjacent VE manifolds.Four
more HAM bellows have been processed in the vacuum bake oven and a new
load is being prepared. We are staying comfortably ahead of the need requirements
for detector installation.
Preparation for beam tube bakeout (Cecil Franklin, Kerry Stiff): We have installed hooks on the beam tube enclosure for ca. 150 feet at the ends of each module. We have installed hooks on the bte for 50 feet at each pump port in both directions. We are preparing to install light strings. We have checked the thermocouples on the beam tube and replaced those which were pulled loose. These will have to be checked again after insulation is completed. The insulation contractor's portion of the warehouse has been cleared. Watt plans to make use of this space beginning April 1. We have spent time cleaning up the site in anticipation of the safety review meeting.
Facilities issues (Gerry Stapfer): The Crane contractor (All
Crane) has been on site to adjust the crane interlock system to facilitate
the load transfer by crane. The pest control people were called out to
help combat the wasp infestations that are occurring at the mid and end
stations. Spraying around the door openings should help in preventing the
wasps from building nests inside the building.
The eyewash and emergency shower station was moved to a more convenient
location (approved by the LIGO safety officer). We have acquired materials
necessary for Carrier to install pressure gages on air and coolant lilnes
at the corner station and end stations (Kerry Stiff).
Construction on the access road is proceeding.
There is visible activity by the contractor.
Electrical engineering (Rus Wooley, Juilien Svoboda): We are now receiving vacuum signals from both end stations via the new fiber optic cable which was installed by MCA! The fiber optic cable was terminated at panel 1X22 and at the mass storage room. The laser safety signs have been wired and installed. Also, 400' of conduit and 4 pair cables were pulled to tie the fire alarm at the end stations to the corner station. We also pulled in one additional cable from the weather station to the mass storage room to allowing paralleling of data acquisition of the weather station signals by LSU and LIGO if necessary. New electrical outlets have been installed in the electronics lab and 120 VAC twist lock receptacles at the end stations have been replaced with general purpose receptacles. We are continuing to receive additional test equipment for the electrical lab and storage cabinetry.
Servo test Stand/Suspension test Stand/Weather Station (Anthony Rizzi):
I successfully wrote and compiled a C program on Vxworks. I obtained
"C" code/EPICS written by Robert Schofield for
communicating with the Davis weather staion. Obtained 162 processor
Manual. Obtained information from Davis about Link isolator from
Davis. Made RS-232 cable to hook from Davis to 162; this setup will,
among other things, be used to understand Davis code to be
used as starting point for talking to LSU data logger. A. Rizzi coordinated
discussions with James Finney, D. Barker, T. Evans, R. Bork and Robert
Schofield to decide best way to incorporate LSU weather station into the
CDS system. James Finney to have partially functioning weather station
tomorrow, Friday.
GRASP installation: GRASP successfully extracted lock acquisition periods from 40m data. "Animate" command is having problem with Xmgr.
Administrative issues (Bonnie Wascom): Eye
exams in connection with laser safety have been scheduled.The check books
are in balance. We have received LLO coffee mugs
at LLO. LLO mugs are also available from Liz Wood at Caltech. (Cost is
$13/each and profits support the LIGO Livingston Employees Recreation Club
and free coffee at LLO.)

Prestabilized Laser -- Peter King
--------------------------------------------
- The motion damper brackets for the reference cavity were examined
and
were found to be made from the incorrect material (stainless steel).
Replacement brackets made from 4140 mild steel are scheduled to ship
overnight
from the manufacturer 03/26. Other carbon steel brackets are
in-house,
should another schedule slippage occur.
- There has been a schedule slippage for the anti-reflection coated
zero
length vacuum viewports. Originally they were supposed to ship
03/26 but
there have been delays at the coater. They will now ship 04/05.
- The servo cards for the LLO PSL are currently being stuffed and tested.
- RF photodetectors are currently under construction for the LLO PSL.
- All intensity stabilization related photodetectors for the PSL have
arrived. These will need a simple modification for intensity
stabilization
at the IO handoff point. For intensity stabilization at the COC
input, a
more complicated modification, involving differential inputs, is involved.
- Installation of the LLO PSL is scheduled to
commence 04/05.

2K Installation -
Finished OSEM installation for MMT22k01-1.
Set up and leveled a bread board in a soft wall clean room enclosure
by
HAM7 to do the OSEM installation for the mirrors out there.
The MC curved mirror had another magnet standoff failure (side
magnet) after baking. No good theories exist for this yet, but
anecdotal
evidence suggests a problem with the fixturing and possibly cleanliness
of
the sides. We removed all the attachments from the MCCM2k01-1
and
re-glued and cured the face magnets. Side magnets, wire standoff
and
guide rod for MCCM2k01-1 are curing.
OSEM installation for the mirrors in LVEA has begun.
Balancing of the spare MC curved mirror (MCCM2k02-1) has been done.
Analyzed the PSL spot size measurement made at LHO. The spot profile
at
the effective mode cleaner waist location are 1.9 mm (horizontal) and
1.7
mm (vertical). Possible causes are misalignments in the MC mode
matching
lenses. This is not a high priority yet.

Global Diagnostics System
(Daniel Sigg, John Zweizig)
John Zweizig
This week I continued to work on the Data Monitor Tool chapter of the
GDS Final
Design Report. I spent Monday and Tuesday discussing GDS interfaces
with
Daniel and representatives of CDS and LDAS. A first release of the
C-language
interface for the background environment is almost complete and Keith
Riles
has expressed an interest in using this as soon as it can be distributed.
Unfortunately, it currently chokes on invalid Frames that are produced
by
FrameL at a ~1% level. I started to look into this problem and Alex
is also
looking into it from his end. I have also continued the development
of
interface routines for use in the root environment.
Daniel Sigg
A diagnostics meeting was held at CIT on 3/22. The following topics
were
discussed:
1. Data Interfaces:
a. test point interface: D.S. will finish the software for the test
point
manager. it will provide functionality identical to other data collection
units plus
the capability to select and change test points.
b. interface between NDS and GDS: the current frame builder will be
able to
support the diagnostics test tool, but the data rates for the data
monitor tool
(DMT) are high and further tests are necessary to determine the best
way to
bring the data out (i.e. ATM or reflective memory).
c. Channel information database: for now every tool will read the channel
names
from its own ASCII configuration file. In the future, this will be
replaced
by a
query tool to the NDS and/or LDAS database.
2. Graphical user interfaces: no decision was made for the GUI of the
diagnostics test tool; possible candidates (all with their own strength
and
weakness):
medm/xmgr (quick and dirty), C++/motif/XRTgraph (complicated?), Labview
or
Java (will need modification of existing diagnostics kernel).
3. Dave B. will start working on the driver software for the ICS115
(digital-to-
analog converters) boards which are part of the excitation engine.
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.More work has been done for the detailed PEM installation
plan, which
will be posted soon.
3. Test were done using the B&G microphones and
the power speaker system
driven by a signal generator. We established a new system for the mounting
of
the microphones on HAMs and BSCs.
4. Matt is in Hanford and will start the installation
of the PEM plates
on HAMs 7,8,9 as well as on other tanks, in function of windows of
opportunities. Also he will try to measure the transfer function of
the
HAMs at
low frequency, between the external accelerometer and various PD signal
from the
optical table. Electromagnetic shakers will be used.

The 44 inch gate test seals were vacuum baked and sent to GNB by R. Weiss. Arrangements have been made with GNB to ship these O-rings to Walker & Sons by the end of this week assuming that GNB "accepts" these parts. M. Fine and I. Petrac are working the procurement details for Walker & Sons for processing the gate seals and return of the seals to GNB. GNB will again perform acceptance inspection after this process and if acceptable, the seals will be installed in the bake test valve. LIGO QA (R. Vincent and W. Tyler) will witness the installation, test setup, and start of the bake test. The post bake O-ring inspection will also be witnessed by LIGO QA. The set of 48 inch mid station gate seals are at MIT for vacuum bake out by R. Weiss. These O-rings will also be inspected for acceptance by GNB and subjected to the Fluoride extraction process unless unacceptable problems develop with the 44 inch gate seal tests.
LIGO QA has also been working with LIGO and Caltech
safety, Livingston site personnel (G. Stapfer and B. Wascom), E. Wood and
R. Torres to complete the Review Agenda, supporting operation/safety documents
and other "details" for the April Livingston Operation and Safety Review.
Hiro started validating multi mode codes, including detectors and telescopes,
by comparing
with Ray's code.
Malik and Hiro worked to ensure that the shotnoise implementation is
correct. Hiro will
improve the telescope code by including the thickness effect using
Malik's implementatio in matlab, whose
result has been compared with IOO beam profile at Handord.
Hiro and Malik talked about an implementation of a very simple 3d suspended
objects, which
may be worked out in a week.
Biplab worked on triangular mode cleaner, and the comparisons between
primitive, summation
cavity and existing pre-mode cleaner data showed good agreement, except
for the width of the resonance.
The obsered width of the resonance is too broad compared to the prediction
using given finess. This will be
discussed with Peter and Rick.
alfi:
Ed has released a new version 3.3, with bug fixes and a few new features.
He also installed
Xlab to automate testing of certain aspects of Alfi.
MOU:
Copies of drafts of attachments of MOU for the exchange of softwares
between LIGO and
TAMA and LIGO and GEO were sent out, and got a feedback from GEO approving
the content. Ed has already
contacted Andreas about the installation of e2e on their machine.
*(AL/JKB/SBA/Wallace) Met to create list of components
that needed to be procured
by late Spring/early Summer for
LDAS phase alpha installation
at LHO. Wallace getting quotes,
putting together PRs, etc.
* (JKB) Discussed a newer, more efficient model for using
the assistant managers
in conjunction with the
communications sockets
within the managerAPI with
Bruce and Phil. This
model mimics the behavior of
web servers and will
allow a closer coupling between
the server and client
sockets. Good work Phil!
* (JKB) Revised the GenericAPI Specifications to reflect
the newer Internal
LDAS Lightweight Data Format
Objects and the supporting
commands in the shared
object library. This
LIGO Doc (T980094-05) has been
submitted to DCC and
posted on the web.
* (JKB) Met with Albert and Tom to discuss recommendations
from the LDAS PDR
review and formulate a response
to these, as well
as propose activities based on
expected actions.
* (JKB) Presented the usage model for the Internal LDAS
Lightweight Data Format
at the weekly LDAS group
meeting. Also discussed
uses of the LIGO Lightweight
Data Format and XML
parsers at the meeting.
* (JKB) Met with Ed Maros to discuss usage of flat files
for database table
storage within the framework
of our ODBC complient
metaDataAPI (client). Such
architectures are
easily supported under Windows
but a bit more problematic
under Unix. An alter-
native would be to
use mySQL for these small tables
that have been discussed
as needed by the LSC
groups at their home
institutions. This does not
effect our own use
of a commercial database within
LDAS.
* (PSE) Checked the development status of a variety of Tcl
packages and extensions,
including new releases of
TclBlend, Jacl, TclXML,
TclDOM, CGITcl, and FTPTcl.
* (PSE) Met with Kent Blackburn and Bruce Sears to discuss
the LDAS API communications
and data flow model.
Proposed a likely
format for the command structure
which will be accepted
by the manager API. See:
http://www.ligo.caltech.edu/~pehrens/asstMgrtcl.html
(Page will not be
available until 5pm 5/25/99)
* (PSE) Fixed some bugs in the genericAPI.tcl which were
introduced by the
necessary changes in the logging
system. Rationalised
all logging to a consistent
format. See:
http://www.ligo.caltech.edu/~pehrens/logtcl.html
(this code is a module
of the genericAPI.tcl)
* (DF) Finished converting ObjectSpace to automake &
autoconfig. We now have a single version of the ObjectSpace library
which compiles on both the Sun & Linux machines.
Autoconfig automatically configures the package for each machine.
* (DF) I have also been investigating the current state
of XML
parsers for C++, as well as the feasibility in
extending the parser for the internal light-weight data to a
validating XML parser.
* (DF) I have been working on generating another release
of
FrameCpp with full
compression/decompression support
as well as other changes
which have been discussed by
myself, Kent, and
John. The coding is complete, I am
writing a series of
test programs to ensure the proper
functioning of the
library. I am also using 'ccmalloc'
to check for memory
leaks.
* (XHU) worked on CDS ilog tables
* (XHU) worked on database views
* (XHU) worked on database queries
Kratochiwill:
- Finished up the web application for searching the frame
tables. Tried
out Javascript for form edits; worked like a charm. Web
application is
awaiting 40m data in the tables.
- Began working on display and update forms for CDS channel
configuration
table.
Williams:
Designing "Scientific Notebook" based on LIGO_LW file format
Implementing parser and XML-based visualization tools for
LIGO_LW
Deploying TclBlend as glue layer between Tcl and Java code
Bruce Sears:
* Continuing work on the definition of Inter-API communications
in LDAS processes
Continuing communication
with Kent Blackburn, Phil
Ehrens, Dave Farnham,and Ed Maros to discuss this and clarify the TBDs
in
implementing inter-API communications. Currently writing pseudo-code
scripts for further discussion and later translation into an actual
implementation.
* Defining scope of electronic log and LDAS metadata service
interworkings.
The LDAS metadata API needs to be able to gather
information from the sites' electronic logs in cases where the operator
makes
a log entry which they feel should be flagged by LDAS.
* Porting electronic log to the Livingston facility.
Involved preparing directory structure, ensuring correct
perl installation, correct web server configuration, setting
up user authentication, and other issues involved in running
ilog on the Livingston web server.
* Maintenance on the Hanford electronic log software (ilog).
Standard work on minor bug fixes
Majid:
Started to implement a method by which we can efficiently
generate templates for a binary spiral using a scaling technique.
Once
the implementation is finished and validated, I will try to
benchmark it against the methods used in GRASP.
Anderson:
The 16 processor prototype Beowulf cluster has finally passed
the initial 100 hour "acceptance" test.
Tom has installed the current version of TeX and now running
Samba on the server. The Livingston group has also been setting
up web pages.
MIT:
Nothing to report.
Hanford:
The Livingston box for the modem pool is configured and
accessible through a terminal console. The modem is programmed
as per the
manual. However, the two are not talking to each other.
The manuals say
they should work. I'm still trying different things to get them
talking.
All of the Sun Workstations have been upgraded to Solaris 7.
The patches for the server to make Solaris 2.6 Y2K compatible are
being installed this week.
The Sun Workshop compilers, upgrade and additional licenses,
have arrived and are being installed this week.
CIT:
The new scanner for general usage had a mechanical problems
which has been repaired and presently is being re-installed by
Samantha.
Once again having problems installing the zip drive on a NT
computer.
Samantha is working the issue with Gateway.
Samantha is continuing her work with the Y2K checkouts on the
PC's as well as working a number of PC hardware issues.
Barbara hanged Livingston links on LIGO home page to point to
www.ligo-la.caltech.edu. LLO is now managing their web site.
Fixed problem with broken links on home page. Turns out the
Excite search engine somehow picked up
www.ligo.caltech.edu/LIGO_web/LIGO_home.html as our home page.
Put a redirect page at that location.
Made a number of changes to Amaldi web site.
Installed February newletter and made several other LIGO web
site changes.
Worked with Samantha to try to get zip drive working on Antares.
Attended town hall meeting on new Oracle financial system.
Suresh installed a 18 GB external hard drive to pollux
(replacement for sirius) to test out the newly installed scsi
board. Also putting on the
last s/w pkgs. needed so that testing can start on the unit.
Presently, testing a system monitoring and management software
called "SyMON" from Sun. This allows realtime performance and
statistics evaluation of a Sun system in network.
Set up couple of user accounts. Restored some deleted users
files/directory from backup tapes.
Taking care of printers maintenance. Follwing up on purchases of
new hardware/software.
We have been working a number of security issues. Mainly,
attempts from the outside world. On the SUN boxes someone has
been trying to
exploit a known NFS bug. Installation of the latest patches appears
to prevent the
problem. If you notice a file called /tmp/bob on your machine notify
someone in
the admin. group, the unit has been comprimised.
Updating the systems documentation and putting it in a central
location with web access for internal use.
Dot Lloyd
Continue to work on reconciling the status reports and entering AP30 reports into the database. Processed the usual heavy load of purchase requisitions, POs, change orders, etc. For further details see Cost Schedule Control Systems report submitted by Sarita Moore.
Continued to monitor and support the temp.
Irene Baldon
Worked on preparing the paper work for various new trips taken recently (23 Purchase Requisitions and 16 Advance Requests). There are 9 additional new trips in various stages pending completion of travel arrangements.
Travel arrangements have started for the NSF Review at the Livingston, LA, site and I have made arrangements for a block of rooms at The Hampton Inn. The NSF has requested a separate block of rooms at The Holiday Inn Express. I am waiting for confirmation of this at this time. At the moment I am reserving cars for the NSF participants and encouraging the traveler to share with someone else who might be traveling on the same, or close to, flight. A decision has not yet been made as to whether we will be using vans again.
Completed 26 Expense Reports. Some of these were still not taped or completed by the Traveler and required more time for completion. Also worked on a number of problem issues which required a good portion of my time. Received yesterday and late Tuesday, but not yet completed my audit, 13 Expense Reports. These should be completed today barring unexpected delays.
Continued to clear 1998 folders, sending them to DCC for permanent storage. I still have a few 1998 individual files not completed with the submission of an expense report. I will continue to contact these individuals as time permits. Please submit your receipts if you still have an outstanding trip.
With the recent mailing of delinquent letters from Travel Audit, I received several calls from the traveler requiring my help in solving problems created when Travel Audit intermingled T numbers or failed to notice the submission of the Expense Report.
Prepared Travel/Vacation Itinerary for the Week of March 22nd, 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.
Rita Torres
Was away on vacation 3/15 through 3/19.
For I. Petrac change order No. 5 to Galli & Morelli, change order No. 9 to Butler Services Group. For E. Jasnow did letter to Pacific Insulation to transmit executed contract PC293660.
For S. Whitcomb copied and distributed Virgo articles. For R. DeSalvo copied and distributed science paper. Ongoing updates on the web page for site trips.
With Safety committee coordinated details for eye exams resulting in prescription laser glasses. Issued memo on the subject to all sites. Sent related material to Livingston.
INFORMATION
Area code change. According to Pacific Bell insert B13397: Beginning April 17 you must dial 1 + the area code for ALL calls within area code 310. All calls require this because beginning on the 17th there will be two codes within the same geographic area. Programmed equipment (fax machines) must be checked.
Time change. Set your clocks forward 1 hour on April
4th, Easter Sunday, for Daylight Savings time. And don't forget to change
your VCR clocks.
Elizabeth K. Wood
Worked with Donna Driscoll, the physics graduate student overseer, to arrange for tours of LIGO for the physics graduate admits.
Continued working on preparations for the NSF site visit with Irene, Bonnie, and Vic Cook.
Attended two meetings concerning the conversion to ORACLE. Don't know what to say about it; it may drive some of us to drink or it may be the greatest thing since saran wrap.
Oh by the way, LIGO contractors can now join the Caltech Credit Union. Don't all rush over at once.
Played with a new program (okay so it's not that new) that makes organization charts.
Discovered the inner door to Phil's new office had been keyed to a non-standard Caltech lock, thus locking everyone out of his new office. We called the lockshop and have now, we believe, successfully locked Phil out of his office.
Dealt with the usual and unusual personnel issues.
