General Items:
--------------
(Fred Raab)
Facilities:
-----------
O. Matherny
Water System modification: All work is complete on this contract.
To close
the contract Parsons designer needs to produce an affidavit that all
the
work was complete according to the contract documents. After this affidavit
is sent to the Washington Health Department
we can remove the non potable water signs.
New staging Building: The building steel is erected and the contractor
is now
bolting out the building, prior to installing the roofing.
Compressors: We wrote a letter to Levernier asking them to honor
the
"No oil in the air stream" guarantee. They are now pursuing the
problem
with Apollo, Electric Air and Kaeser, the installer, supplier and the
manufacturer of the compressors.
Bake Oven:
----------
(K. Ryan)
Last week's news:
LHO vacuum bake oven A load #24 consisting of three 10" optics
(s/ns FM01-A, 2ITM01-C and 2ITM04-C), two 3" optics (s/ns MCFM06-1
and
MCFM01-1) and 4 T-Block washers was released early last week. The cable
controlling the main turbopump vent valve lost electrical contact 28
hours
into the cycle (late Saturday night) of this load which caused the
oven to
vent. The automated monitoring system detected this abnormality and
triggered the autodialer which phoned Bartie and I at home. I was able
to
come in and fix the bad connection and recover. The scans passed and
it
was decided not to rebake (heated for 72 hours, UHV for 60 hours total).
LHO vacuum bake oven A load #25 consisting of one folding mirror support
structure (s/n D970508B-002), misc PEM, RGA vacuum fittings, four L
brackets (Larry Jones stuff) and some misc. elliptical baffle SS parts
were loaded 4/8.
This week's news:
LHO vacuum bake oven A load #26 consisting of two 10" optics (s/ns FM01-A
and 2ITM01 C) will complete their vacuum bake cycle tomorrow. Load
#27 is
to consist of Kapton cables and some eliptical baffle parts.
Bartie is now routinely cleaning class B hardware for anyone who has
a
need. Put "to be cleaned" class B hardware on the appropriately labeled
shelf on the wheeled rack in the Vacuum Bake Oven Room and pick up
clean
class B hardware on the so labled wheeled rack in the Vacuum Prep Lab.
He
is doing this on a daily basis, if you have to process parts faster
than
this, you should clean them on your own.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
BSC 8 work: Vertically actuated Optics Table 6mm down to nominal
position
in preparation for Optics Installation (4/9).
BSC 4 work: Downtube was inspected by Betsy Weaver prior to installation.
Trace amounts of particulates, similar to those found on other Allied
components in other chambers, were found but the amount was not
significant. Downtube was installed (4/12), and connected to Support
Tubes.
Holes on Support Table, for stack Safety Pins, were checked for
perpendicularity; ran into noticeable drilling/tapping problems on
the
holes for BSC8. The holes for BSC4 were within the desired tolerances.
Bellows were partially installed. Next step is to take the load of the
Support Tube/Downtube via the V-block assemblies on to their final
mounting
configuration on the Crossbeams; temporarily, the load is being taken
by
fixtures mounted to the Crossbeams (4/13).
It was noticed that the NW Scissors Table was not properly seated. It
is
supposed to be dowel pinned to the Adapter plate below it, but for
this
Scissors Table the Dowel pin was not seated in its hole. To fix the
problem
portions of the Air Bearing were removed and the Scissors Table was
lifted
high enough so that the damaged Adapter Plate could be swapped out.
After
this fix the Crossbeam had to be re-positioned in place; this is a
bit of
a complex manuever and will be done today.
It was also noticed that BOTH Crossbeams were shifted westward a noticeable
amount. The reason for this shift is a bit of a mystery; a similar
shift
was also seen on ONE of the Crossbeams on BSC8.
After these fixes are taken care of, the Support Tubes will be connected
to the Crossbeam via the V-blocks, the Bellows will be completey installed
and finally the stack will be built.
Other notes: Thinner stack shims were fabricated for all BSC chambers
(LHO & LLO). This is to help improve on the final vertical position
of the
Optics Table.
PreStabilized Laser:
--------------------
(Rick Savage)
Examination of the PSL EPICS records indicate that the intensity
stabilization servo loop has been ineffective for approximately fifty
percent of the time over the past two weeks. With the help of the CDS
Data
Viewer (and Dave Barker) we are investigating the cause. We have
changed
the servo gain and set point. The stabilized output power level, measured
with a Scientech calorimeter at the PSL output, is now 6.7 watts.
Optics:
----------------
(D. Cook and B. Weaver)
Last week we received the elliptical baffle hardware from Mike Smith,
cleaned it up, and had it vacuum baked by Bartie and Kyle. It
came out of
the bake Monday, and is wrapped and ready to go for installation. Today
we
received the second box of glass that matches the hardware mentioned
above.
The glass was safely delivered to LHO, thanks to the new and improved
packing design from Ed C. I believe that the glass will be the next
load
for the vacuum bake oven (VBO). This load should start up Friday or
Monday.
Currently, the FMy (Folding Mirror) and ITMy (Input
Test mass) are being
baked for the 4th and 3rd time, respectively.
Yes, magnets broke off of
both mirrors Friday and Saturday. Mark Barton
was able to repair the damage
by patching the magnets back on. This was however,
the show stopper for
last Friday's planned installation of the FMy.
We'll hopefully get these
mirrors out of the VBO Thursday or Friday, resuspend
them, and continue on
with the installation.
During our down time this week, Doug has been continuing to make the
needed
modifications to the installation fixture, and I have been tidying
up the
optics lab (which was badly needed) by adding some shelves, redefining
work spaces, and recleaning tools and tables.
Computing Systems:
------------------
(C. Patton)
The phone lines for the modem pool have been installed. There
will be
one phone number which will switch between four phone lines/ modems.
The modem Larry sent up last week is talking to the Livingston box.
The
user accounts, IP addresses, login protocols and other configurations
still need to be setup before the modems will be usable.
I'm still trying to get a quote from Sun Sales on 20 Solaris 7 licenses
to upgrade the GC and CDS computers. Added several new user accounts,
did the usual weekly backups, and answered multiple "How to" computer
questions.
Electronics/Electrical Systems:
-------------------------------
(R. McCarthy)
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
Still cooking, but regenerating cryopumps in expectation of endgame.
The two bellows that were leaking on HAM's 1&4 have been successfully sealed (thanks also to Kerry Stiff for assistance with this). The copper gasket situation is not clear at this time. I have contacted both Varian and Nor-Cal in an effort to understand differences between the two manufactory, but as yet don't have a good picture. Nor-Cal gaskets were used on the fixes. We have taken a new RGA scan of the VE and an air signature remains. No idea were this is from, except we are confident that the bellows assembliesare leak free. We will vent the system Friday for detector installation. (Allen Sibley).
Optics & Vacuum Labs: The suspended ceiling and electricals in the PSL Safety Enclosure are completed. Two additional flow benches have been ordered for the Vacuum Prep Lab. Five ISC pier locations have been located, and cored in the LVEA and both endstations. The 6x12" softwalled cleanroom is assembled, and located over the suspension surface plate in the Vacuum Prep Lab. Sany Yoshida arrived Wednesday, and Helena Armandula arrived Thursday for inspection visits. A 10' security fence has been installed around the shop area in the staging building. (Jonathan Kern).
Beam tube bakeout: PII continued to work on the X-2 module. As
of this time, PII has completed
approximately 7/8 of the module first layer of insulation. PII has
increase their work force to ten employees, four employees are cutting
insulation material in the staging building and six employees are installing
the cut material on the Beam Tube. PII has given LIGO an estimated completion
schedule for X-2 module insulation installment of 4-24-99. We continue
to order and receive consumable supplies for the bake out. Randy
the "the tin-man " has come and cut our openings for the insulation and
electrical connections to pass through on the X arm. (Cecil Franklin,
Kerry STiff).
Suspension Test Stand T. Evans and A. Rizzi have configured the
Sun for Suspension test
stand and have set it up in the Vacuum Lab (the room containing the
VME rack for the Stand).
Weather Station More verification this week that connecting CDS through data logger control port will work. C code now being written to collect data from data logger of professional weather station. James Finney to hardwire data logger today and get some software running over the weekend. Work begining on Medm interface for weather station. (Anthony Rizzi)
Miscellaneous: PSL - Workers setup thru G. Stapfer to flush cooler for PSL and to clean enclosure. GRASP - Xmgr problem resolved. GRASP is now capable of animating 40m data. GRASP now basically up and running. Servo Stand - awaits computer setup on LLO1 for cross-compling C and state notation code. (A Rizzi)
Facilities The proposed location for the LVEA observation room was discussed with Fred Asiri and Otto Matherny. It appears that the location best suited for LLO is at the intersect of the north-east bays. This provides a maximum view of the LVEA while minimizing interference with the HVAC system. It will also be relatively easy to have dual access/egress from this viewing area which should alleviate any safety concerns.The contractual arrangements with Gulf Engineering have been completed to initiate the design and specification package for the erosion/landscaping work.
A contract has been issued to Borg Warner Protective Services to provide security for LLO during off hours and weekends. This service is scheduled to start Monday April 19, 1999 and should considerably improve our security.
Work on the access road is continuing and should be going well as the
weather is holding. Since we do not have a schedule for this work, it is
difficult to assess when the road will be completed. (Gerry Stapfer).

Interferometer sense/control (Zucker)
--------------------------------------
IAS Intitial Alignment (K.Mason, M. MacInnis)
--------------------------------------
Alignment of the Y-arm FM and ITM did not occur due to magnet problems.
#MZ note: Zucker will go to LHO week of 4/26 to try again.
Four optical lever grout plates have been shipped to Hanford.
The remaining 8 optical lever photodiode assemblies for Hanford have
been assembled. The remaining 8 laser assemblies are being assembled
and
will be shipped to Hanford next week.
ISC implementation (P. Fritschel)
----------------------------------
o I began a measurement at Hanford of the dynamic RF amplitude
modulation on the laser beam that exits that EO modulator(s).
When modulation is applied, some noise in excess of the shot
noise is seen in the demodulated output of an RF photodetector,
at baseband frequencies below a few kHz. More tests are being
planned to further characterize and control this effect.
o Re-examined the layouts of detection tables ISCT9 & ISCT10
with Ken & Matt, and came up with a final parts count for
ordering.
Optical lever and ISC table fabrication (Matt Smith)
-----------------------------------------------------
We reviewed the procurement items for ISCT10 and ISCT9 and reduced
a
number of items that were purchased. This required a handful
of change
orders for POs allready in process. There were no problems with
the
vendors given th changes that were made.
Only one quote has come in so far for the new Otical Lever table.
All
the quotes are due by the end of the day today. The POs need to be
placed by tomorrow. I started to organize the drawings to the
optical
lever tables for DCN filing.
I received the rails required for modifying the receiver optical lever
on BSC8 that is for the WA 2K folding mirror. I painted them
today and
shipped them to Hanford. They are due to arrive at Hanford Friday.
ISC code development (Ed Daw)
-----------------------------
{MZnote: this is Ed's report from last week,
which was inadvertently
omitted from the final report. Ed's on travel
this week.}
This week I worked with John Leffingwell, an M.I.T. undergraduate
with us for a UROP (undergraduate research opportunities program)
placement. He has learned how to compile C code for the baja
processor, use VxWorks commands to manipulate control bits on
the baja and reflective memory modules and is generally learning
very fast. I also read Jays schematic for the ASC and updated
the isc header file to include the control and error bits he suggested.

--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- Another delay has been encountered with the zero length vacuum viewports
for the reference cavity vacuum chamber. Inspection of the window
material
revealed some flaws that were not picked up by the supplier of the
window
material. The defect was located in the middle of the viewport
and is
attributed to a bad batch from the manufacturer. Nor-Cal has
promised to
have another set of viewports delivered to Caltech by 04/26.
A partial
shipment to LLO will also occur, since Team PSL will be down at LLO.
- The construction of a quad photodetector and decoder is almost complete.
Thanks to Jay for the photodetector board. The quad photodetector
will be
used for gathering performance data of the PSL.
- Finishing touches to the LLO pre-modecleaner servo card are being
applied.
- The next round of the LLO PSL installation will commence 04/19.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
2k Installation
One of the MCCM mirrors and one of the MCFM has been shipped to CIT
for
cleaning by Helena Armandula to remove the traces of silicone that
were
found on the mirrors. These mirrors will be shipped back to LHO
for
gluing sometime next week. The other MCCM will be then get the
same
treatment.
Peter Fritschel did measurements of the RFAM spectrum after the resonant
EOM driven at gamma=0.5 by taking the RFPD output, mixing it with the
LO
that drives the modulator, and looking at the audio (GW) band spectrum
of
the IF mixer output. There were a couple of problems related
to getting a
clean signal on the photodiode through a 45 deg pickoff mirror and
a
polarizer was inserted after the EOMs to fix these problems.
The two main
results were 1) when the RFAM was minimized by the polarizer adjustment,
the RFAM spectrum was at the shot noise level (4 mA of photocurrent
on the
PD), down to a frequency of about 3 kHz; below 3 kHz, it rises fairly
slowly, at about 2 dB/octave, and levels off between 40-200 Hz at a
level
that is ~7dB above shot noise, and, more importantly 2) the effect
is
dynamic - after about 30 min the DC RFAM had gone up by about a factor
of
20, and a broadband white noise was observed, at about 5dB above shot
noise; tweaking the polarizer angle again brought back the lower noise
level.
More measurements are needed to track down the origin of the low frequency
excess noise and the dynamic effects: better pickoff of the signal,
dependence on LO phase, correlations between this signal and PSL
oscillator signals, long term drifts and environmental dependences.
Livingston 4-k IOO
The parts for the IOO table (EOM's, lenses, mounts and stages, pzt
actuators, etc) were shipped to LLO this week. We shipped several
optics
and components (vacuum-use rotary stages, 2" fixed mirror mounts, 3"
optics and various mounts and other components for PSL/IOO table
to
Livingston site, and stored them in the vacuum preparation lab in
Livingston site.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
BS01 was delivered to the OTF April 9th for cleaning and subsequent
shipment to Hanford. We attempted a measurement off the AR coated
side,
we did get a data set, but it was quite noisy due to poor fringe
contrast.
We are currently performing a three flat test at 20 degrees C (brrr).
With this data we should have a more accurate reference to subtract
from
the recent test piece measurements which were done at the same
temperature.
We often see vibration effects from the machine
shop showing up in the
data, the appearance is a ~1nm grating which
shows up clearly in
differences of consecutive measurements.
This becomes most apparent
during times of thermal stability.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
Magnet bonding issues: Testing of the new bonding
procedure showed a shear
strength on magnet/dumbbell assemblies of 3.3
kg. before cleaning and about
1.5 kg. after cleaning. Improvements on the bonding
procedure and revision
of the cleaning process is ongoing.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS
Rework is being done on the cavity beam dump vertical support structures.
Craig and Paul are finishing the layout and detailing of the horizontal
support structures and the triple flexure mounting brackets. Rotary
flexure
joints have been received for the beam dumps in BSC8, BSC7 and BSC4.
Shipping containers were build and sent to the glass fabricator. The
glass
will be fabricated this week and sent to LHO on 4/19.
PO TELESCOPE
The 1st article PO telescope mechanical housing is complete! Ken M.
is
compiling a set of revised drawings for final production. Delivery
or the
parabolic mirrors is expected by the first week of May.
ETM TELESCOPE
Ken M. has begun checking the shop drawings for the ETM telescope.
A bid
package will be sent out early next week.
PO MIRROR
Still awaiting a few minor mechanical parts for 3 sets of PO mirror
assemblies.
VACUUM WINDOW
Awaiting REO high transmissivity AR coatings on 6 windows, and Varian
conflats.
ELLIPTICAL BAFFLE
All mechanical parts have been cleaned and baked. The AR coated elliptical
baffles for RM, ITMx and ITMy were shipped to LHO. Special shipping
containers were designed and built with the help of Ed Chargois, and
the
two containers of glass arrived unbroken to LHO. Mike S. will be at
LHO
from 4/19 to 4/23 for installation of ITMy elliptical baffle (if the
ITMy
is aligned). A hole for the optical lever beam will be added to the
RM
elliptical baffle while Mike S. is at LHO.
ITM/ETM ARM CAVITY BAFFLE
Paul K. is in process of making 2D working drawings.

Seismic Design (Mike Fine)
--------------------------------------
1. Scissors Tables:
Hytec have received the first shipment (eight total) of scissors table
from
Superior Jig. During assembly of the spring cups, they found
that the spring
cups would not thread into the female holes on the scissors tables.
This
would indicate that either the holes are too small or the cups are
too
large. However, Hytec were able to correct this problem using a 2 3/8"
GH4 tap
(.005 oversize tap according to SJ). We now have measured the pitch
diameter
of the cup thread to be oversized by .002" so it could mean that we
will have
to either rework the cup or re-tap the holes on the scissors table
to oversize
for future assemblies.

Global Diagnostics System
(Daniel Sigg, John Zweizig)
We reinstalled the latest version of root, and have been
developing, improving and documenting the tools (classes and functions)
which
may be used for analysis and display of online data under root. Functions
that
are now installed and working are manipulation of basic data types
(GPS times,
time intervals, complex numbers), creation of time series objects on-line
from
specified channels, manipulation and plotting of time series, (brute
force)
Fourier transforms of time series to create frequency series, manipulation
and
plotting of frequency series, creation of physics templates.
The software of the diagnostics test tool (DTT) was ported to the most
recent SUN
SparcWorks C/C++ complies. No real problems were encountered. Development
of the DTT supervisory task has started. The DTT supervisory task is
divided into
a synchronization task which is common to all tests, a test iterator
and a test
task. The test iterator is used to repeat a test, to scan through a
parameter space
and to find optimum values for parameters. The test task implements
the actual
test which can be a sine response measurement, a swept sine response,
an FFT
test or a triggered time series measurement. This approach has the
advantage that
test iterators and tests can be mixed freely. Also, if a new test will
be
added at
later stage, it will work with the existing test iterators immediately.
Physics Environmental Monitor(Matt Smith, David Shoemaker & Alex
Marin)
-----------------------------------------------------------------------
The seismometers are on track to be shipped to the distributer on April
23. The distributor will test them and we should receive them
the first
week in May.
The granite plates for the tiltmeters and seismometers were shipped
today and should arrive at the sites next week.
Received the plates that are to be used for the accelerometers on the
PSL/IOO tables and they can be installed. They were shipped today
and
should arrive at Hanford on Friday.
Optical Contamination (Daqun Li)
--------------------------------
The contaminated mirrors in the recent contamination
event have been
sent to Rai Weiss for further analysis. New mirrors
have been installed
in the cavity which is empty right now. Initial
measurements did not
show additional scatter and absorption losses.
Further evaluation of
this cavity is underway.
New set of fresh viton seats without DI water
treatment has been loaded
into another cavity. This cavity is under vaccum
pumping.

MC LSC:
=============
Mostly this week was spent working out a schedule for the 2K one Arm
Lock
proposal while supporting IO installation at LLO. We are also cleaning
up
some documentation and ordering parts.
Timing System:
=============
On hold until we can get to it.
IO ASC
==============
New version of the WFS demod board has been layed out and is ready
to be
fabricated. The changes made include a different method for applying
the PD
high
voltage bias and a few minor schematic fixes that were discovered during
initial
testing.
DAQ
==============
The generic DAQ interface boards have been received and a few will
be stuffed
for use on the 2K IO LSC and PSL.

Assisted the Detector Group with a work order to Caltech's Carpenters Shop to construct several plywood boxes to satisfy the different sizes of glass being shipped from the Vendors to the Hanford and Livingston Observatories. Acct # 5F511.
Received a notice from the NSF concerning the Trade-In Policy, which requires a report to this office whenever an obsolete piece of equipment is turned in to a Vendor for trade-in value. Necessary instructions will be provided to appropriate individuals concerning the format and information required.
ACTIVITY HIGHLIGHTS
With all Livingston construction as-built drawings
now available electronically, began the process of placing the Hanford
construction as-builts on-line. Hopefully by next week these, too,
will be available. Reviewed PSI's electronic submittal of as-builts.
Unfortunately, there are numerous types of files, and it hasn't yet been
possible to convert them to .pdf format files. Ed Jasnow will see
if PSI can resubmit the electronic files in .pdf format. This would
certainly make our processing
easier.
Changes were made to the DCC web pages so that hyperlinks for on-line documentation can be accessed from remote sites.

LIGO QA has ordered additional Fluorel O-rings
for the Livingston beam tube gate valves. It was also decided last week
not to have these O-rings subjected to the Walker & Son Fluoride Extraction
process. (When the original test seals had been run through the extraction
process, two of the four seals were reported to have changed in length
and crossection size). This has also delayed the gate seal sticking test
at GNB pending delivery of replacement test seals so the sticking test
will be conducted with seals that have not been through the extraction
process.
* Modeler - multi mode
The implementation of the field has been discussed by Matt, Biplab and
Hiro, and a revised class strcuture is being palnned by Biplab. This
new
strcuture is more flexible when the mode base changes, and is more
streamlined in descrtibing the whole optics system. Polarization will
also be explicitly included.
* PSL
Rick will organize a regular meeting for the simulation effort.
* IOO
Sergei sent us a status report, road map to the completion and special
primitive modules for IOO. He has implemented several mirros
for
different purposes.
* Mechanics
Cella reported a solid progress in his modeling. He finished the
formulation finding the equilibrium operation point, which was the
additional caluclation we discussed when Cella visted last time. He
will
provide an API of his mechanics class to interface with e2e environment.
* alfi
A new version is released which includes bug fixes which caused
recursive flickering and halted the editing. The user preference, like
dsiabling "transparent bitmap", is automatically stored and restored.
The status of editings, which boxes are opened and/or displayed, when
one quits alfi, can be automatically restored after restarting alfi
next
time. Alfi is now available via the e2e homepage.
* e2e talk in Japan
Kawabe of Univ. Tokyo gave a talk about e2e at Kamioka and was well
accepted. Ohashi of ICRR, who said that young sceintists are
very
interested in e2e, replied to our draft of MOU attachment about the
simulation effort, and both sides will sign on the final one very soon.
* (BK) Finished up the editting forms for CDS Channel Configurations.
Today I'm doing a final
check of all the web forms (there are 8)
and then will send the site
over to Rolf for comments.
* (PSE) Installed the genericAPI.so and frameAPI.so packages
locally.
* (PSE) Wrote wrappers for the genericAPI.so and frameAPI.so
for use by the genericAPI.tcl
and frameAPI.tcl into
the sock:: and frame::
namespaces.

probably have a face to
face meeting next Wednesday.
* (BS) Continuing work on the definition of Inter-API communications
in LDAS processes
Developed document for the
specification of communications between LDAS
end users (the User API)
and the LDAS Manager API. This communications
specification is called
the User-Manager Protocol (UMP) and includes
the syntax of requests and
responses as well as the mechanics of the
connections between a user
client and the Manager API.
* (BS) Upgrading the Hanford and Livingston electronic log software (ilog).
Added capability for users
to include externally viewed objects
such as postscript, pdf,
etc. in their ilog entries. Previously,

Edward Maros:
1) Installed Software: less v335, fileutils v4.0, rsync v2.3.1, Electric
Fence
v2.2.0
Stuart Anderson:
Transferred another 0.5TB
into HPSS. The race condition for getting
stuck metadata within HPSS has been identified and fixed by IBM.
The Alta Beowulf cluster
has been recabled up so that the box can
be closed and the remaining broken hardware returned to the vendor
now that
we have a stable platform (>1 week without a hardware crash). Note,
this
includes the reconnection of the serial cables to allow the use of
minicom
for remote hardware debugging.
The LDAS 600MHz Alpha box
running Linux is now in testing mode for
complete network integration into the CIT network (NIS+ accounts and
NFS).
Interested users are encouraged to login to sadan.ligo.caltech.edu
and report
any problems encountered to sba@ligo.caltech.edu.
Started work on a perl script
to manageautomate public domain
software installation.
Livingston:
Working on procurements and normal setup of machines. Recieved and
installed
Mathematica on a PC.
Hanford:
The modem pool phone lines have been installed. There will be
one phone
number which will switch between four phone lines/modems. The
modem
Larry sent up is talking to the Livingston box! The user accounts,
IP
addresses, and login protocol still need to be setup.
Tried to contact Sun Sales to get a quote on 20 Solaris 7 licenses.
Added several new user accounts, did the usual weekly backups, and
answered multiple "How to" computer questions.
CIT:
Sam removed hardware components from old NT machine, formated the hard
drive
and is currently rebuilding it using 95.
Finished preparing Syd's machine, ready for his use.
Fixed the parameters on ED's monitor.
Worked on the NT machine that has bad zip drive. Tried a bunch
on ideas
to make it work, including installing service pack four on it.
None have
worked thus far. Will call gateway again and try installing it
using
secondary blade.
Still trying to copy Gari's disks, may have a CD rom problem or CD
burner
problem.
Fix the DVD player now fully functional. Instructions on using the
scanner and
burners have been posted on the wall next to the unit.
Ed configured a new unit for LDAS along with setting up a new users.
Barbara finished the web page for Parsons' LLO drawings. The link
is
http://docuserv.ligo.caltech.edu/docuserv/home/asbuilts_la.html
on the Internal Bulletin Board under Documents and Publications.
The html was generated by importing the file names in the as-builts
directories into an Access table and merging with DCC data in a VB
procedure.
Changed the procedure for submitting abstracts on the Amaldi web site.
Added a memo field for the Abstract to the server pages and database
and
changed the prose on the web pages. Fixed up the computer generated
email
message that is sent when someone submits an abstract.
Made a couple of enhancements to the web forms for submitting an LSC
MOU
progress report and sent the site to the team for review.
Helped fix the links on the DCC web pages so folks at MIT can open
the
PDF files. Added links to the DCC home page on the Internal Bulletin
Board.
Suresh installed ATM adapter board in newly arrived Ultra 10 and is
connected
to new ATM switch (ASX 1000). This is for testing the switch serving
as an
independent network before swapping it into the existing network.
Installed Adobe Framemaker version 5.5 on a test server. Some tests
were
performed to see licenses issues are correctly set up before putting
it
on-line for general usage.
Installed solaris 2.7 in newly arrived Ultra 60. This will act as one
of the
LIGO servers. This unit is also being used to investigate solaris 2.7
features.
Reworked a number of maintenance contracts
for both software and hardware.
Also, preparing to install the last of the pkgs. on the new server
to continue
testing of that unit. Processing a number of purchases with SUN and
FORE for new
equipment as well as upgrades. Resolved a number of issues concerning
the modem
pool and networks on campus. It appears LIGO may get connected to the
new CITNET2000
backbone in the next couple of months. Going over the proposed new/additional
network
connections at the observatories. Received a number of new PC's and
SUN boxes which
are now in the process of being placed and installed.
Irene Baldon
Worked on preparing the paper work for various new trips taken recently (14 Purchase Requisitions and 6 Advance Requests). There are 17 additional new trips in various stages pending completion of travel arrangements. Travel arrangements continued with a number of late reservations for the NSF Review at the Livingston, LA, site. LIGO has a block of 50 rooms at The Hampton Inn, and the NSF has requested a separate block of 20 rooms at The Holiday Inn Express. I'm reserving cars for the NSF participants and encouraging the travelers to share with someone else who might be traveling on the same, or close to, flight. A decision was made not to order vans for this meeting.
Completed 51 Expense Reports, many of these were extensive, involving 2 to 4 pages each. 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, 9 Expense Reports. These should be completed today, tomorrow at the latest, barring unexpected delays. I'm holding 4 expenses reports which require additional information or missing receipts from the traveler.
All 1998 travel folders have been cleared of any pending expense reports. I have sent them to DCC for permanent storage.
Prepared Travel/Vacation Itinerary for the Week of April 12th, 1999.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as from members of the staffs of each of the two (2) sites.
Rita Torres
Was away for a day and a half this period. For I. Petrac did change order No. 13 to Hytec, and distributed change order No. 2 to MIT on the PX contract number.
For P. Lindquist distributed Quarterly Progress Report for period ending February 1999. Set up telecon for the CCB which took place on 4/14/99. Also did more labels and such to help organize reports in his office. Did ongoing site trip updates on the website.
Met briefly with L. Wallace to discuss pricing information from Pagenet and AirTouch on email/voice capability. Need to pursue better pricing elsewhere.
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 area codes within the same geographic area. Programmed equipment (fax machines) should be checked.
Dorothy Lloyd
Continued to work on reconciling status reports and updating PO Logbooks. Processed the usual heavy load of POs, reqs, change orders, check requests, etc. Tracked and followed up on various invoice problems. Continued to monitor and support temporary help.
Elizabeth K. Wood
Contacted Physical Plant about the mice and rats hanging out in the basement of Bridge Annex. Damaged ceiling tiles are being replaced. An exterminator will be coming, if one hasn't already visited, to investigate a somewhat more permanent solution to the recurrence of our fuzzy visitors.
Please be careful with the account numbers to which you charge items. We had an instance sometime in the recent past of $1500 worth of goods being charged to an account number in Kellogg Radiation Lab. The issue has been resolved. Don't let it happen to you.
Arranged to have locks on the sixth floor of Millikan changed. Even more people I can lock out of their offices.
Ordered various and sundry supplies in anticipation of the impending NSF Review.
Attended a meeting with Gary, Joann and Alan of the PMA office, and three auditor-like people concerning the use of LIGO's space.
With Dave Beckett's help, located some transparencies of aerial shots of the two sites for Prof. Emlyn Hughes to use for a prefrosh talk.
Gathered together the preliminary reading materials for the NSF Reviewers. Continued with preparations for the big week.
Just a note
to those of you involved in the NSF Review who have gotten this far in
the Admin weekly report: The NSF Dry Run will be Wednesday, April
21, 1999 beginning at 9:00 a.m. in the SCR. I will still need your transparencies
preferably right after the meeting (dream on, Liz). If you need time to
make corrections, I will need your complete package by no later than Thursday
morning like say, oh, about 8:30 a.m. If you can't get them to me by then,
we need to talk.
