The Project Control Meeting Agenda for Monday February 15, 1999 will be:
CANCELLED DUE TO CALTECH INSTITUTE HOLIDAY
AND MARDI GRAS IN LOUISIANA!
Weekly
Report Highlights
At long last, MMT3 is hung at LHO!
The dome is off LHO' s BSC8 in preparation for the first seismic installation in a BSC
General Items:
--------------
(Fred Raab)
MMT3 is hung and aligned with
valiant assistance from a large and dedicated
crew of people! (See D. Cook's report below.)
Betsy Weaver is
assuming duties as the Core Optics Support (COS)
liaison at LHO and starts
reporting on COS activity at Hanford this week.
For trivia fans, last year 200 tons of tumbleweed
were baled at LIGO
Hanford Observatory.
Facilities:
-----------
O. Matherny
Water System modification: Apollo is 82% complete with the water
modification project. The 8000 gallon tank was transported back to
the
factory for re work. It is scheduled to be back on site on 2-16-99.
New staging Building: George Grant Construction Company is installing
the
conduit bank from the transformer to the building. In addition they
started
on the outside concrete work.
Compressors: We are in process of trying to get our money back from
Kaser, since they guaranteed that we will never get any oil in our
air
lines. Kaser is asking many non relevant questions. It seems they would
like to wiggle out of their guarantee.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A loads #14 (rebake of one 10" and two 3" optics)
and
load #15 (three HAM bellows + misc silver plated fasteners) were released
this week. There was no evidence of the "mysterious"
discoloration of
silver plated parts in either of these two loads
(see last week's report).
It is therefore safe to assume that the source of the discoloration
was
likely not the copper gaskets as previously surmised but rather one
of the
parts comprising load #13.
Bartie has taken ownership of the Vacuum Bake Oven room and has already
made some real world improvements. This week he purchased and installed
glassware drying racks around the sink area, added a "user friendly"
hand
held water sprayer (big improvement over preexisting faucet) and installed
an additional electrical panel which will house three additional variacs.
He has begun to demonstrate his ability to oversee most of the routine
operations and, in doing so, has freed me up to revisit some of the
data
integrity issues I've been needing to address.
Throughout loads #1 thru #14 I was never able to maximize the RGA
sensitivity to approach the advertised value (partial pressures of
5E-13 torr). I would get either one of two errors when trying to maximize
the electron multiplier gain (1E6). Discussions with the manufacture
(Stanford Research Systems) revealed a possible glitch in the code
of the
PC software. To get around this, they had me defeat the PC software
via
command line interface. Using this approach, I was finally able to
get the
RGA gain up to ~800,000 (up from ~245,000). This improved the signal
to
noise ratio by a factor of about 500 and, starting with load #15, we
can
now quantify partial pressures which had previously been buried in
the
noise. As such, I will now be routinely subtracting out the background
signal from the post-bake scans (previously the background signals
were
buried in the noise).
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
HAM work
This week was moderately quiet for HAM work. Leveling/elevation setting
for HAM9 Optics completed. There is still a minor fix which needs to
be
done on the electrical cabling for HAM9, but this just depends on some
parts being cleaned.
We received the Optics Table for HAM10 and a crate of recleaned Leg
Elements.
Corey assisted/observed MMT3 installation/alignment.
BSC work
Dome for BSC8 was removed.
It was a fairly tricky manuever mainly because
of clearance issues, a touchy crane and a tight
fitting clean room roof; we
were able to remove the Dome with the Clean Room
legs at their "longest
setting". Working platforms which attach to the
dome flange were fit
checked (two platforms needed to be modified),
and four bellows work
platforms were installed.
Shipment of DownTube, Support Tubes, Leg Elements, and other components
were received. There are a few items we are still waiting for to begin
installation work, namely a custom made spreader bar (available next
Tuesday), and a new clean room sock/roof (available next week as well).
IAS
The MMT3 optic was placed on HAM7 2-10 and aligned.
This may be revisited
after full electronics control is enabled.
Optics & Lasers:
----------------
(D. Cook)
Thanks to everyone who helped with all the separate
operations needed to
install the MMT3 optic into HAM 7. We also have
a few new people that
gained experience with one phase or another in
handling and processing the large
optics. The learning curve of the first attempt
helped us to successfully
install and align MMT3 to it's global coordinates
in HAM7. The actuators
were tested and dampening was achieved. We will be checking table
elevations and adjusting heights as there is a possibility of slight
changes when the counterweights and optics are exchanged. We will be
prepping the Recycling Mirror and hopefully installing and aligning
it into
HAM 9 by Tuesday. We will use the same process that was followed for
MMT3.
The Input Test Mass will be the next Core Optic to come alive at Hanford.
The IOO optics will start to be placed into HAMs 7 & 8 on Friday.
This
includes several Small Optic Suspensions and steering mirrors as well
as
the Faraday isolator. The IOO baffle will hopefully be set in place
today
or tomorrow. We are documenting changes and variances from the original
plans.
Core Optics Support:
--------------------
(B. Weaver)
A month into my new job here at LIGO, and I suppose it's time I become
a
member of the weekly reporters. In the last few weeks, I have been
familiarizing myself with the core optics and the many procedures that
come
with them. The team of people that work with these optics have been
kind
enough to let me observe and participate in the handling, cleaning,
suspending, balancing, and transport of a large optic. It's been
a great
experience so far!
I received the parts and pieces of the COS IO Baffle about three weeks
ago
and spent some time cleaning them and getting them ready for Kyle's
bake.
They completed their bake last week and were moved out into the softwall
enclosure surrounding HAMs 8 and 9. While continuing my involvement
in
lending a hand to the COC group, I have cleared a work space for the
assembly of the baffle and am prepared to do the assembly today (2/11)
with
the help of Corey. The baffle will hopefully be installed later today
or
tomorrow. The baffle installation must be completed before other
installations to Ham 8 can proceed.
Computing Systems:
------------------
(C. Patton)
We now have AutoCAD 14 working on both Guest computers in the OSB common
area. I replaced the broken ZIP drive on the Guest 1 computer
and
bought another ZIP drive which will be installed in the Guest 3 computer
in the Computer User's room.
The backup tapes for both General Computing and CDS are now being stored
in a fireproof file cabinet in the Comms/Server room. I have
started
learning how to install and setup the Livingston Communication router
and modems for our modem pool. I have started learning how to
programm
the Cisco router to provide security for our T1 line connections.
One P5-90 PC is ready to go into the LVEA for general computing users.
The other one has a bad hard drive, which may not be replaceable, I'm
looking into it. Larry Wallace is planning to send more P5-90
PCs up
here to be put in the Mid and End stations for general computing users.
Electronics/Electrical Systems:
-------------------------------
(R. McCarthy)
The cable tray for the Seismic Isolation controls have been installed
around all the BSC's. This is to allow for the multiplexing of
controllers. There will now be two racks for the controllers
and routing
the cables became an issue. We are now prepared to install the
cables.
The Shutoff button for the PSL has been extended
to the control room. This
will allow the laser to be turned off in the
event of an emergency without
going into the LVEA. This also provided me an
opportunity to bring the
laser up from scratch for the first time.
Thank you Peter King.
Thanks to Jay Heefner for his assistance in getting the MMT3 suspension
controller operating. CDS can now control
MMT3 from EPICS.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
The bake out of X1 is going very well,
and we are currently raising tube
wall temperature to 168 C. We shut down the bake Tuesday (2/9/99)
to
regenerate the Cryopumps at all the ports along the tube and temperature
dropped from 159.81 to 79.43 . We regenerated the cryopumps at
ports X1-1
and 9 with out shutting down power and with these regenerations we
will be
able to complete the bake.
The weather at Hanford have been very breezy (sustained winds of 50
to 60
MPH) with gusts up to 70 MPH as recorded from the bakeout weather station.
The tumble weed population along the X1 arm has increased by 100 bales.
A pre bid conference was held at the Livingston site for the insulation
of
the beam tube for all contractors who may submit a bid.
Vacuum Equipment (Allen Sibley): We have received the parts to
install the RGA for VE baseline measurements
and are in the process of assembling them. Approximately one
half of the bake blankets used by PSI, pumps, leak
detector and miscellaneous parts have been shipped from LLO to LHO.
They should arrive 2/15 in Hanford.
We are preparing the vacuum prep oven for its first load of bellows
to support detector installation.
Beam tube bakeout preparation (Cecil Frankin, Kerry Stiff): We completed 800 ft of temporary lighting within the BTE for the pre-bid job walk held 2/10. Four potential insulation contractors attended the job walk. Ed Jasnow and Bill Althouse were also present for the job walk.
Electrical Engineering (Juilien Svoboda, Russ Wooley):
Fiber Optic Cable Installation: The contractor has finished
the beam tube section. They are having difficulty getting a bigger
trenching machine to re-dig the trenches. (The old trenches they dug earlier
have been destroyed by the rain). The final test date will be postponed
to next week. The ATM ethernet switches have been installed at both end
stations. Once they are ready to feed the cables through, we will be ready
to test and set up the network system at both end stations.
EE Lab: I have ordered a big wall storage unit and some more
tools. This should help our lab storage problem in the future.
LVEA network: I have rewired and checked the software connection
between the CDS server and each VME controller boards. They work well.
VME Test stand Setup: Some software packages are installed in
the SUN to help the test setup. Due to disk space problems, we have to
install in a different area versus the default. So far we are having trouble
making a good link to this software.
Control Room Cabling: Two 6" cable trays are now installed from
the Mass Storage Room through the Control Room and into the Computer Room.
They are lacking the splice kits which are on order. MCA is still a week
away from being ready to test the fiber and copper cables. Russ will perform
a walkdown of the x and y arms tomorrow.
LVEA CDS Installation: The 10 CDS racks that are required for
the x arm have been set and will be bolted down to the floor by the end
of this week.
Anthony Rizzi: A. Rizzi, Tom Evans and Mike Werda have successfully installed Linux on a 16 Gigabyte hard drive on one of the PC's. The second disk now needs to be setup to allow Windows 98 to be run as an alternate operating system. The PEM cart computer is now fully on the Network; it can be seen by the Network as well as see the Network. The PEM cart cable has been ordered by Bonnie.The end-to-end model is now completely on the Sun. It has been successfully tested from the Sun, but is not available over the network yet. There is a known bug associated with running over the network with Exceed for the PC. Tom Evans is in process of setting up one of our new Sun's as a Sun file server, so that the end-to-end model can be operated remotely from a Sun until the Exceed bug is solved. Tom Evans has installed Solaris 5.6 onto the test-bed Sun in the room across from the control room.
Facilities (Gerry Stapfer): The Environmental Protection Agency
of Louisiana inspected our domestic water system. Their reading of the
rules and regulation is that if 25 or more persons are on the premises,
the drinking water system becomes a quasi public system and is subject
to inspection. He found a few minor items in addition to the chlorinating
system which has not yet been connected by
Bernhard. He will write up an inspection report documenting his findings,
but told me not to worry about anything, that we are in "fine shape".The
sewage treatment plant has been modified to provide a better quality discharge
water. This involved the readjustment of floats which operate the lift
station, decreasing the batch size which gets treated. About one half of
the Vacuum system bake out blankets and sundry pumps and equipment have
been shipped to Hanford. This alleviated some of our overcrowding of the
staging and storage building.
Other: Photographers from the National
Geographic were at LLO Feb.7-9 to take pictures for a theme issue about
exploring the very large and very small which will come out this October.
We took advantage of their being here as an opportunity to invite the local
high school year book club out to LIGO for a lecture by the lead photographer,
Joe McNally. Joe did a wonderful job showing slides of his work and telling
about his experiences in photojournalism.
Mark Coles visited La Tech Univ in Ruston, LA on Feb. 10 and gave the
Physics Colloquium there. La Tech has received the RefTek data acquisition
system from Hanford and will come to LLO on 2/15 to begin making trial
measurements.
40 m Interferometer (Nergis Mavalvala)
---------------------------------------
Shark was "mended" and we were able to pump down over the
weekend. Thanks to Anthony R, Phil W and Alan W for help with
the vent and pumpdown. And to Rick S and Larry W for successful
surgical maneuvers on the 40m vacuum controls computer.
The mirror cleaning appears NOT to have removed the terrible
blemish on the South End mirror and scanning the beam over the
surface of that mirror we are able to find the bad spot again.
Away from the bad spot, visibility of about 14% is measured.
Similar ~13% visibility is measured for the east arm.
The windmills work well and are already proving useful.The
windmills are picomotor-driven beam stops, apertures or optical
loss elements which can be rotated in and out of the beam path
(like the arms of a windmill). They were made by Jamie Rollins,
our UMich visitor.
Despite our earlier concerns, the in-vacuum Pockels cell (PC) is
healthy and previously measured throughput was recovered with
input alignment. We are now realigning rest of the ifo since PC
alignment changes the input beam direction.

Initial Alignment and ISC Tables (K. Mason, M. McInnes)
--------------------------------------------------------
The ISCT-7 assembly drawing was completed and placed on the Caltech
ftp
site at /pub/kmason/D980493-A-S1.pdf and D980493-A-S2.pdf for review.
A drawing of the optical lever grout plate locations for Louisiana was
created and sent to prevent interference with BSC grouting.
A new procedure was developed to align MMT3 to
eliminate translations
which were believed to be the cause of error
during the alignment trial
of MMT3 in Hanford.
ISC Implementation (P. Fritschel)
---------------------------------
o Continued working on the control screens and associated code for
the ASC system.
o Finalized the layout of ISCT7 (reflection port sensing table) with
Ken. We set up another laminar flow bench to begin assembling optical
components for this table, using parts previously received for the
IOT tables.
ISC Implementation (N. Mavalvala)
------------------------------------
Drafted a Standard Operating Procedure (SOP) for operation of the
100 mW ISC alignment laser (Crystal Laser) in the LVEA.
ISC Supervisory Control Software (Ed Daw)
------------------------------------------
This week I got the isc supervisory hardware
working at MIT again - my ddcu code from Hanford
now contains hooks that allow you to compile it
to run without a working data acquisition system
attached. Also, I re-configured the MIT VME
crates so all the target processors are on
a private subnet. I have started incorporating the
newly updated header files for the DAQ and ISC front
end reflective memory layouts into the isc supervisory
code.

--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- The intensity stabilization AOM has been sent back to the manufacturer,
along with the analog driver and rf amplifier, for checking.
- A new PZT is under test for new versions of the PMC. The PZT
is
capable of moving approximately 5 microns for 150 V. The test
is to see if
the PZT stack bends under load when driven. An initial test indicated
that
there was some bending. However another test, performed well
after the
drying period of the epoxy used to adhere a mirror to the PZT, did
not
indicate any signs of bending. The new PZT has a few other desirable
characteristics, such as a low capacitance and high resonance frequency.
- Orders for the remaining electronic items needed for the PSL servo
cards
have been placed.
- A drawing of the IOO/PSL optical table position for the 4k IFO has
been
checked. The coordinates given in the drawing were found to be
consistent
with each other.

Installation -
More Radii of curvature measurements - Stan, Malik, Qi-Ze, and
Hugh
measured the RC of several of the 3" optics via geometrical focusing.
The
separation distance was measured using a Theodolite, white light
illuminator, a target and a microscope. Multiple readings from different
people were used to obtain an average RC and error estimation.
Sources of
error include: distances to each end from the instrument (0.002m
each),locations of the prism (0.002m each), focus point reading on
the
rail on which the target and the image plane are moving together.
Results:
MMT3
To check if the ROC of MMT3 was uniform across the entire clear aperture,
the spare MMT3 was measured again with with a 3" aperture.
a) For whole aperture, R=25.019+/-0.005m. (Previous
measurement
gave 25.030+/-0.015).
b) For 3" aperture, R=25.004+/-0.006m.
This has negligible effect on mode-matching and can be compensated
by a
1.5 cm repositioning of MMT2.
MMT12k02-1
a)Whole aperture, R=11.334+/-0.006m,
b)1" aperture, R=11.330+/-0.016m.
MCCM2k01-1.
Whole aperture only, but the coating is apertured, R=21.406+/-0.019m.
Optics Preparation -
The magnets continue to
cause problems after baking: MCCM2k02-1 and
MCFM01-1 were baked with MMT3 and came out of
oven late Sunday. First run
of cleaning did not produce a wetted HR surface
so we decided to repeat
the process. One magnet fell off in final rinsing,
and one fell off
after the rinse. Helena is heading up a tiger
team to address
this problem. To increase the throughput, we
are running spares of all
optics through the entire preparation procedure
with the hope that one of
the optics will survive....
Diagnostics Installation -
Sany set the optical spectrum analyzer at the designed location on the
PSS
table. We installed a new version of the Shack-Hartmann wavefront
sensor's software, and reconfigured accordingly.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Measurement of FM01 at 0 and 45 degrees has shown agreement along a
vertical data line to within the measurement noise of +/-2nm peak to
valley. We have measurements at 0 and 90 degrees rotation in
the 45
degree configuration. We are completing the measurement of FM01
at 0,
45, 90 and 180 degrees rotation in the normal incidence configuration.
The optic will be handed off to Steve Bell for cleaning and is expected
to ship by 17 February.

for the
floating stage and have begun the Air Bearing Mounting Plates for the
driven stages. This includes all of the mounting plates for both
facilities. Hand Precision has also begun manufacturing the flexural
pivot
assemblies for all of the actuated BSC's. However, the flexural
pivot
assemblies will not be ready for the 2nd and 3rd BSC assemblies.
They will
be ready for all subsequent assemblies.
2. Rack Assembly
Rack wiring has been completed. Hytec installed the multiplexer
trays and
computer into the rack. Hytec has connected AC power to the rack

Global Diagnostics System
(Daniel Sigg, John Zweizig)
John Zweizig
I discussed of the representation of times in the LIGO analysis software
with
Walid and Dave. I then wrote a preliminary implementation of a C++
time class
and put it out for comments. This will hopefully be improved and agreed
upon,
after which a C implementation can be derived from it.
I discussed the interfaces between the data monitoring and CDS (Network
Data Service and Alarm Management) with Rolf et al.
I started to rewrite a (hopefully final) version of the data distribution
code for the data monitor tool. This differs from the prototype system
in
that the frame access will use the new FrameCPP library rather than
Fcl,
and the data pusher will receive data from the Network Data Server
in frame
format rather than having to translate from the CDS proprietary format.
The change in frame libraries is because FrameCPP allows an easier
and more
standard interface to the shared memory buffers and because the upgrading
and maintenance of FrameCPP will be driven by LDAS. At present I have
implemented the shared memory interface classes and I am testing them
with
the new FrameCPP code in the Data Pusher application. Once the data
distribution is working in this mode, I will implement the frame interface
to the NDS.
Daniel Sigg
Continued to work on documenting the arbitrary waveform generator, the
test
point interface and the diagnostics interface.
Talked wit Rolf B. about the implementation of a GUI for the arbitrary
waveform
generator.
Updated the DAQ channel list.
Physics Environment Monitoring (M. Smith, D. Shoemaker, A. Marin)
--------------------------------------------------------------------------
1.No change on the delivery schedule which is posted
at :
http://web.mit.edu/marin/www/PEM_Delivery.html
2. In the middle of March, if the delivery schedule
is respected,
we plan to start the instalation of the seismometers at both sites.
In
paralel, the tiltmeters will be instaled in the PEM stay clear zones.
3. Also in the middle of March, the accelerometer
interface plates
will be installed, starting with the 2km IFO tanks.
4. At LHO two RGA are now installed on HAM 11 and
BSC 8. Most of the
hardware for two more RGA has been prepared or ordered.
5. The RGA hardware for LLO HAM5 installation has
been shipped.
Also an dedicated RGA PC for LLO has been ordered, expected deliver
March 1.
6. Toghether with Daniel Sigg, Rich McCarthy, Rick
Savage, Rolf we
are working on the PEM final channel count and cable installation plan
at
LHO.
Optical Contamination (Daqun Li)
--------------------------------
After weeks of preparations, CO2 cleaning qualification has been
started with one of our contamination cavities in vaccum. The
pre-qualified cavity mirrors were given CO2 blast over the entire
surfaces (both HR and AR) for more than ten times, then the mirrors
were put back into the cavity undertaking vacuum pumping. The initial
ringdown and mode spacing measurements from these mirrors, cleaned
with CO2 snow, did not reveal any additional losses beyond the
measurement repeatability (10 ppm in total loss and 1 ppm in absorption
loss) due to cavity disassembly and reassembly. I am planning to
continue to monitor the data for at least one week to see whether or
not the losses will stay stably.
Still taking ringdown and mode spacing data from cavity two with air
baked steel with no contamination observed. The air baked steel can
be concluded acceptable in LIGO and this cavity will soon be used to
requalify the second set of viton.

LIVINGSTON OPTOMECHANICAL LAYOUTS
Optomechanical Integrated Layout is being put together.Tentative
completion is estimated to be 2/16/99.
INPUT OPTICS (IO) BAFFLE
The majority of the details and assembly are completed.
Minor
dimensioning of a couple of parts and completion of assembly
bills of material is
scheduled to be completed and released by 2/22/99.
ITM/ETM ARM CAVITY BAFFLE
Design is nearly complete for this baffle which
will used in the X &
Y arms, both n the vertex & the end stations. Detailing with materials
lists &
release documents should start by 2/24/99.
RELIABILITY
Visited with CDS ISC/LSC people to determine design status.
Installation/Integration of other observatory subsystems continues
to take
a priority. The CDS Groups priority at this time is the installation
of
the Input Optics support systems. They estimate that it will
be another
4-6 weeks before they start seriously attacking the ISC/LSC design.
Hiro made Frequency Shifter and other modules were developed for the
modeling of PSL.
More generic detector shape is now supported.
The use of transparent Bitmap made it happen, under certain conditions,
that the icon is not properly drawn. Anthony Rizzi reported this problem,
and Ed has decided to fix it.
Several bugs were fixed.
* (PSE) migrated the service validation routines
(these
are the functions which determine
whether requested
services are valid within the
context of a given API.
Services include access to API's,
machine sockets,
specialised interpreters, etc.)
into a single call.
This functional group is a part
of all of the API's
communication code. This
migration was made to
minimise code duplication and
to standardise the
format of the return values for
all procedures requiring
validation of service calls.
* (PSE) began coding a functional "demo" per
Kent's
request. This demo will
make use of all the functionality
of the generic and manager API's
to process simple data
requests with logging and monitoring
of processes and
communications enabled.
* (DF) Completed beta version of the FrameCPP
library.
* (DF) Ported ObjectSpace to run on Solaris
with the egcs compiler.
* (DF) Implemented method to getAttributes/Data
in the Frame API.
* (DF) Converted internal LDAS light-weight
data format to use
namespaces.
* (DF) I am in the process of adding the LdasContainer
object to
the genericAPI, this object is
used by the Frame API as well
(to return data sets).
(BK)
- Had a brief meeting with Rolf Bork about databases for their channel
configurations and for slow channel data.
- Began work on a WebBase interface for the LDAS DB2 database.
Met with Roy
Williams who set up a working environment on Bill computer at CACR.
* XHU worked on GDS trigger database
The tables in the GDS tables
include:
datasource
fpgeneric
fpftt
filter
transformeddata
ppgeneric
program
triggers
One problem with the GDS
tables is that each filter
and each program has its
own parameter list. As a result,
the filter parameters and
program parameters cannot be
put into a single table.
After extensive discussion with
JohnZ, Kent and Ed, we decided
to classify filters and
programs so that each filter
and program will have its own
parameter table. I also
studied the possible database access
scenarios and how they can
be handled by SQL. More filter
parameter tables and program
parameter tables will be
constructed soon when JohnZ
finish the filter and program
classification.
* XHU worked on LDAS log database
LDAS log tables are constructed
with the help of Phil Ehrens.
Anderson:
Configured new server for Beowulf cluster, and replaced faulty disk
drive
in the cluster. Started work on configuring a newer version of Linux
to
better support the multiple processor (SMP) systems we have.
Lazzarini:
Worked on reviewing programmer resumes for hiring 2 programmers.
Met with Wallace on planning meetings with PNNL on vBNS for LHO and
with LSU for
vBNS for LLO.
Working to complete PDR document for LDAS. I have asked D. Shoemaker to chair PDR and he has accepted.
Bruce Allen joins us as a visitor for ~6 months starting this week.
Met with Weiss to discuss the agenda for an upcoming LDAS-LSC meeting
at Caltech on 26 February.
One of the P5-90 PCs is ready to go into the LVEA, just waiting for
help
to get it moved over the beam tube. The other P5-90 PC has a
bad hard
drive. Christene is looking into replacing the hard drive.
Christene replaced a broken ZIP drive in one of the guest computers.
Purchased
more network cables, spare keyboard, spare monitor and a spare ZIP
drive. Purchased and setup a fireproof file cabinet for storage of
the
backup tapes.
Larry has been running some tests to get the e-mail server on-line.
Checking
with Caltech to make sure the DNS tables are correct.
Worked on web page for as-built drawings.
Because there are so many drawings
(~700), the web pages will be generated by a
Visual Basic procedure written
against the DCC database. Changed the procedure
to incorporate most recent
changes requested by Fred Asiri.
Installed quick changes to web site for upcoming LSC meeting.
Suresh Working on new mail server with qmail. Now that mail can
be sent and
received by both the Sun boxes and PCs. Still work to be done on aliases
and
other items before putting it online.
Resolved couple of PC related problems. Moved some users to different
home
directories in order to make room for the existing home directories.
Some paperwork on purchases.
Sean has been working on getting things setup for the LIGO unit replacement
which will not be too soon since there have been some major problems
with the
existing unit.
Worked with Larry, Rick and Steve in getting the computer in the 40M
back
on-line.
Samantha installed a couple more PC's. We have an epidemic of old PC's
having
major hardware problems. There will be a number of units shifted around
as we
trickle the units down. Larry and Suresh have been assisting in a number
of the
of the moves and installs.
Working on a number of purchases and reorganizing the computer room
to
accommodate the server replacements.
Rita Torres
For I. Petrac did PC291438 with University of Pisa for R&D of low frequency seismic attenuation chains. Distributed MIT change order No. 1 on the new PX number. Did change order No. 29 to the previous MIT number -- a special circumstance. Did change order No. 4 to Innovative Data Processing.
Shuffled meetings on the calendar to accommodate two separate meetings (and telecons) for Detector and SEI Installation. The LLO installation will be discussed on Monday mornings, and LHO will be done per usual on Tuesday mornings. Updated LHO and LLO trips on the website. Lately this has required my contacting individuals to obtain details (I. Baldon has information for some).
For P. Lindquist, distributed minutes to CCB that took place on 2/8/99.
Helped I. Baldon copy travel documents.
For W. Tyler/M. Zydowicz did more updates to Safety Manual. The manual is now 43 pages, from the original 57 pages. Emailed additional pages for M. Zydowicz review. Arranged for eye exam and broader laser training for T. Prince.
Irene Baldon
Worked on preparing the paperwork for various new trips taken recently (18 Purchase Requisitions and 15 Advance Requests). There are 11 additional new trips pending completion of travel arrangements. Completed 24 Expense Reports. Some of these were still not taped or completed by the Traveler. Received in the late afternoon mail (yesterday Feb. 10th) 8 new Expense Reports and 5 this morning. These will be completed today, or tomorrow at the latest, and sent out for approval and then forwarded to Travel Audit. I am still experiencing a large influx of expense checks which requires recording, filing and distribution to the individual traveler.
I pulled 124 individual 1998 travel folders, sorted, cleaned out, and sent them to DCC for permanent storage and made up the 1999 folders for these same travelers. There are still 17 folders to be completed. These are folders containing Visitors, Job Applicants, Consultants, and various conferences.
Prepared Travel/Vacation Itinerary for the Week of February 8th, 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.
Dorothy Lloyd
Continued to work on heavy load of paperwork with problems needing to be resolved, and processed many invoices and receivers for payment.
Processed the usual heavy load of purchase requisitions, POs, change orders, etc.
Managed to do a little data entry and work a little on reconciling the status reports.
Continued to monitor and support the temp.
Elizabeth K. Wood
Made space arrangements for visitors. Also contacted the phone office about getting Phil Lindquist's extension moved to his new office on the third floor of West Bridge and a second new extension for the outer office. I don’t know when the lines will be moved; things are in a state of chaos in the phone office.
I will be sending a memo over to the Caltech bookstore updating them with the new LIGO charge account numbers.
Dealt with the usual personnel and PAN form issues.
