The Project Control Meeting
Agenda for Monday June 14, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
General:
--------
After many delays, we now have light in the HAMs
and busy optical alignment work going on.
Unfortunately, I have missed all the fun while preparing for the oncoming
Y99 problem at Caltech
- aka "the dark period" when all business systems will become inoperative
- and playing catch-up
in land-use planning with the Department of Energy (DOE). The comment
period just closed on a
revised draft of a DOE land use plan to cover the 560-square-mile Hanford
site for the next 50
years. Luckily, a colleague at PNNL tipped us off in time to get a
foot (toe?) in the door as it
closed, since we did not get an official notification and my 1996 contacts
in the planning office
have all been retired or promoted out of contact. Current planning
lists limited mining as an
allowed activity on lands adjacent (or in the DOE preferred plan, underneath)
LIGO. My earlier
interactions with the DOE planners have ensured that a conflict between
mining activities and
LIGO operations is acknowledged in the document, but our extreme sensitivity
to mining
operations and the physical extent of the conflict - mining within
10-25 miles of LIGO could
threaten future LIGO sensitivity - is not emphasized. Our goal is to
get proper language into the
land use documents making the magnitude of the problem evident and
to arrange formal NSF
representation (presumably us) on any future panels that alter planning
documents or make
land-use decisions at Hanford.
Facilities:
-----------
(F. Raab for O. Matherny)
Otto is preoccupied with getting ready to leave for court in Spokane,
WA, on Monday (ACME
lawsuit) and participating in an Ed Temple review at Oak Ridge later
next week. Otto and I did a
walk-through of the staging building, which should be ready within
a month. On Monday, June 21,
there will be a power outage on our X arm (but not the corner station)
associated with
transformer hook-up for this building. We also now have CCB approval
to implement erosion
control, paving (including additional parking!) and landscaping of
the new building.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #35 consisting of three HAM bellows was released this week.
Load #36 consisting of three HAM bellows and one HAM leg screw kit should
begin it's vacuum
bake tonight and be completed on Monday 6-14-99.
Recently, I proposed (still waiting for a response) modifying the HAM
support tube test fixture so
as to make it suitable for use as the long awaited vacuum bake oven
"B". If approved, this ~ 1.5
cubic foot vacuum bake chamber could expedite the vacuum baking of
small loads, i.e. fasteners
etc.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
BSC 8: The Coarse Stage Translators have been swapped out with a set
that have limit switches
installed. To meet installation schedules, the source provided
translators without these switches.
The Optics Table has been set to its design location using the Coarse
Actuation System (CAS)
Rack and the Rack has been relocated to its permanent spot where it
will operate the CAS for
BSCs 4, 7, 3, & 2. The Rack for operating BSC 8, and 1, will
be built in the future.
BSC 4: With the CAS Rack moved, the CAS cabling and motors for BSC 4
have now been
installed with the exception of two cables; we are expecting these
cables anytime. Similarly to
BSC 4, the translation stages have been exchanged. Additionally, the
Coarse Flexures, providing
tilts and twists to the actuation, were installed; and the Flexure
Fixtures were sent to LLO for their
installation use.
BSC 7: The CAS UV motors have been installed, and similarly to BSC 4,
the Coarse Flexures
were installed; the Flexure Fixtures at now at the Y-Mid. Also,
various installation hardware and
fixturing has been removed from BSC 7 and relocated to BSC 6 at the
Y-Mid.
BSC 6: The Coarse Actuation Stack alignment has been completed with
the assistance of recent
HS graduates Jonathon Oberg and Fred Henderson.
HAM 10: The Airbearings are currently being installed in HAM 10.
INITIAL ALIGNMENT
RECYCLING MIRROR: The RM was realigned after the reworked OSEMs were
reinstalled.
PreStabilized Laser:
--------------------
(Rick Savage)
The 2k PSL shut down unexpectedly on 6/8 at about
7 PM. The 10-W laser power supply
displayed a PS Fault condition. The source
of the fault is unknown. This is about the fifth time
this has happened since the laser was installed
last December. The system was restarted right
away and is operating as expected. R. McCarthy
will connect a line monitor to the power supply
source.
The IOO/PSL optical table output aperture shutter was removed to allow
the IOO group to
direct the beam into HAM 7 for alignment of their optics. The
LVEA is now in the LASER
HAZARD condition.
We finally have PSL fast channels connected to the data acquisition
system. Rana Adhikari and I
modified the recently installed DAQ interface module such that the
maximum output voltage is +,-
5V and set gains for the ten PSL channels that are currently available.
We are in the process of
verifying that each signal is behaving as expected.
We received a shipment from Lightwave Electronics that includes a 10-W
laser head and
(hopefully) a power supply. When time allows, L. Cardenas will
uncrate the laser and set it on the
4k PSL table. He will ship a chiller up from Caltech when he
returns after next week.
B. Bhawal is up from Caltech to work on the end-to-end model for the
2k interferometer. We
are in the process of constructing the model for the PSL control loops.
This mainly involves
determining the as-built transfer functions of the electronics, sensors,
and actuators.
Optics:
---------------------
(D. Cook & B. Weaver)
We are in the "Laser Hazard" condition at the
Hanford site and will likely
remain there for a couple of weeks. This is the
first time the PSL laser beam
has actually left the laser area enclosure and
is being introduced to the
vacuum chambers. A reduced 100mW beam
is being used to align the PSL laser
to the Input Optics in HAM 7 and the 15 meter Mode Cleaner (HAM7 and
HAM8).
Dave Tanner headed the fairly large team and carefully reviewed the
work
that was to be performed. As part of this review we discussed
the laser
safety precautions that were to be followed. As with all major activities
it takes a while for the process to gain momentum, but we are on a
roll.
Betsy and I processed the ITMy-2k and FMy-2k optics and have them ready
to
be transported to BSC8 for Monday's installation. We will be staging
equipment and installing the first of the installation fixtures today.
The
ITM baffle will be measured for center line and readied to attach to
the
structure as well. I will continue to assist the IOO team when needed.
We
have also setup an additional balancing optics table in the optics
lab to
parallel the processes of the LOS optics. We continue to process
sub-assembles for the LOS optics as well.
Computing Systems:
------------------
(C. Patton)
All the disk space on the server, rainier, is full. I'm expecting
more
disks to arrive this week or next. Until then I have asked several
users to delete any unnecessary files from their accounts and I have
been cleaning out unnecessary files in the system directories. I had
to
restore, from the backup tapes, one file that was lost due to the full
disks. Actually, users have been very helpful about deleting
files and
some of the user disk partitions went from 100% full to 58% full in
one
day.
Worked with Ed Jasnow and FORE Systems trying to get a maintenance
contract for the ATM equipment put together.
Moved a GC Sun workstation from the EE lab to the Computer User's room
to accomodate the recent influx of Unix users.
Electronics & Electrical Systems:
---------------------------------
(R McCarthy)
The grounding of the BTE is 3/4 of the way complete and I expect it
to be
complete by the end of next week.
Began tying the O2 monitors in all the buildings to the EPICS system.
This
will allow for alarming in the control room should oxygen level in
the
buildings drop below acceptable levels.
All of the GPS cabling and antenna are installed on all buildings.
With the arrival of the Xycom 220 boards we were able to complete the
installation of the LOS controllers. Modifications to all the
controller
daughter boards were made.
Worked with Jay and Dale on the ISC installation.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
We shipped out the remaining bakeout equipment in 2 20' containers week.
We also shipped some equipment for detector installation in this load.
The
2 power supply trailers and 45 KVA transformers will be shipped the
end of
this month. Mark Guenther will be going to Livingston next week
to help
set up the data system and verify operation. This
will be the last report
from me on bakeout or the equipment
from Hanford.
Detector installation Staging for installation of the BSC seismic system continued. Also, preparations for installation of additional survey monuments for the ISC are in progress.
Optics All of LLO's LOS-s have been cleaned, and are awaiting their turn in the bake oven. Two additional 30x72" breadboards have been received, which will be used for the new flowbenches in the vacuum prep area. One complete set of laboratory hand-tools has been cleaned and air baked for suspension/optic work. Ordered tools and hardware for Peter King and Rich Abott. Spent Monday identifying an elusive problem with the site water system. An air-purge vent has been opening erratically and spraying a stream of water up to the roof, which we have never seen (I thought the roof was leaking). Not normally a big deal, except the leak has been right on top of the pump switchgear, getting on some controller boards and tripping the GFI, completely shutting down site water. Had to disassemble two controllers, clean and bake the water out. Fortunately they were not permanently damaged. Installed a vent line hose to the floor drain, which fixes this problem.(Jonathan Kern)
CDS: The Livingston CDS web site is now ready for review. Some areas are still under construction. To access the site, go to Juiliens home page. The SOS controller for the suspension test stand is installed. The test box for the controller is being fabricated in Pasadena. It should be here in a couple of weeks. Rus has talked to Proxima about the multimedia projector demonstration. They are making arrangements to have the demonstration in our control room (date TBD). The cable tray in the corner station lacks 6 supports and grounding. The supports should arrive today. Cable tray installation in the south end station is underway. The communication problems with the GPS slave board have been fixed. We have received 3 new boards from Rolf. Two for future use and a spare. The two broken I/O boards have been shipped to Rolf for warranty work. (Rus Wooley, Juilien Svoboda)
Beam tube bakeout: The power to the bake transformers is being installed by DEMCO and power will be available by Mon. Pipe stands that need to be moved for alignment have been. Two containers of bake hardware have been received from LHO and have been unloaded and inventoried. (Allen Sibley)
Bakeout: The forepump on the bakeout oven is failing, and Varian is shipping us a replacement. (Tom Evans)
General computing: We have ordered IslandDraw.We are eligible for Caltech's site licenses for several software packages, andthey are going to provide us with information on access. (Tom Evans)
Weather Station: Short haul modems installed, new operating system installed on Data logger. Problem of glitches in data much improved but not eliminated. Error correction program checked and found to have bug..now in process of fixing it. James Finney still working on Web version of weather. Recieved 162 processor that can be dedicated to weather station. (Anthony Rizzi)
GRASP Began collaboration with Dr. Adrian Ottewell of UK in our efforts to get key parts of GRASP to recognize LIGO frames. Problems with dcu unit and GPS cards have kept us from pulling over more LIGO data. The problem was fixed today again. But, underlying reason for crashes of this system is still being explored. Guralp seismometers to be shipped from IRIS consortium to arrive tomorrow. (Anthony Rizzi)

Prestabilized Laser -- Peter King
--------------------------------------------
- After ~6 days of pumping the reference cavity vacuum chamber with
the
dedicated ion pump, the pressure is ~2e-8 torr.
- The tidal servo hardware has been installed. Characterization
of the
Minco PID controller's performance has been done and the PID parameters
have been programmed into the process controller.
- The frequency shifting acousto-optic modulator has been aligned with
a
single pass diffraction efficiency of 92%, using an rf drive level
of 1.5 W.
The double-passed output is expected to be modematched
into the PSL
reference cavity some time today (06/10).
- Some PSL signals that were monitored with a 3113, 12-bit ADC board
have been
moved over to the 3123, 16-bit ADC board because of problems observed
with
noise in the signals. The signals moved over include:
PSL-FSS_RMTEMP /* ambient
room temperature */
PSL-FSS_RCTEMP /* reference
cavity vacuum chamber temp. */
PSL-126MOPA_AMPMON /* laser power (unstabilized)
*/
PSL-126MOPA_126MON /* master oscillator power */
PSL-FSS_RCTRANSPD /* reference cavity transmission
*/
PSL-PMC_PMCTRANSPD /* pre-modecleaner transmission
*/
Lightwave Electronics
=====================
- Recently two 10-W lasers were returned to Lightwave
Electronics because
of an observed drop in performance. The
two units being #107 and #108.
Unit #107 was returned because of a degradation
in the output power of the
laser. Unit #108 was returned because the
output power measured at Caltech
was not consistent with that reported by Lightwave
Electronics in their
test report.
#108 was realigned and the
power amplifier diode current was
increased to yield an output power consistent
with 10 watts being in a
TEM00 mode.
The master oscillator and alignment
of #107 was checked and both
were found to be okay. Inspection of the
power amplifier pump diodes
revealed that 4, arguably 5, out of the 8 diodes
were not performing to
specification. The specification for the
diodes, as per the manufacturer
SDL, is that at an operating current Imax, the
diode should put out approx.
20 W of 805 nm light. The 4 diodes that
"failed" typically put out approx.
16.5 W and the 5th diode put out just over 17
W. The accumulated time on
the laser was 608 hours.
Lightwave Electronics were
going to return the diodes to SDL for
failure analysis.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
IOO - Dave Reitze, UF
Hanford 2-k IOO
We aligned all the optics on PSL/IOO table. For RFAM measurement, beam
path has been slightly changed. In order to have ~10" z-shaped path
consisting of two additional mirrors with near normal incident, we
moved
the three EOM chain toward HAM7 by ~10" (in other word, we lost 10"
in
this way and regain the same path by having the new z-shaped path).
The
new z-shaped path is before the first mode matching telescopic lens
so
that the distance from the telescope to the mode cleaner is unchanged.
We replaced the original polarizer before the EOMs with a Brewster
polarizer and added another Brewster polarizer after the EOM chain.
For
this change,the beam path at the EOM chain has been raised by 5 mm.
Accordingly, the EOMs have been raised by the same amount.
Mode Cleaner Alignment
Guido, Sany, and Dan have begun the mode cleaner alignment. The
PSL
beam has been aligned through the periscope and into the HAM7 viewport.
Initial alignment revealed a slight mispositioning of the first steering
mirror into the mode cleaner. It has been moved for realignment.
LLO 4k
No significant activity to report.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
SPETM03 was handed off 6-7-99 for cleaning and shipment to Hanford.
SPETM04 is currently "on the stand." Either the chilled water
or the
building temperature has been going crazy lately, we're waiting it
out in
hopes that our previous set-point, which got us +/- 0.15 degree stability,
will return. Fortunately the delivery schedule for the next ETM
can
support this.
Staining has been sighted on 4ITM01, the decision was made not to coat.
We're looking into possible causes and may ship it back to CSIRO for
inspection.
Invoices for the CSIRO contract are being examined in detail to be sure
that all items have been addressed. The last optics have been
received;
Core Optics polishing is complete.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO contract- COC's coatings: Two of the parabolas have been baked and
will
be ready to ship as soon as they are inspected. The other two will
be baked
tomorrow.
The HR side of two SPETM's will be finished this afternoon.
Monday was lost, trying to get SPETM05 cleaned.
The second set of SPETM's cleaned within the normal time frame. The
HR of
the second set will start coating tomorrow, running into Friday. Calibration
runs for the SPTM's AR will be done over the weekend. Monday and Tuesday
the
AR coatings will be placed on these optics.
Wednesday we expect to coat the HR side of the 4kITM's to be received
shortly, and, Thursday they'll get the AR coat.
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE
4 primary mirrors have been coated by REO (3 primaries will be sent
to LHO,
and 1 will be sent to CIT). SORL has 4 more primaries completed, and
the
parents for the remaining primaries are also completed awaiting
segmentation. SORL is edging 6 secondaries and will ship 4 to REO on
6/16
for coating on 6/18. Ken M should complete the production drawing package
by 6/18.
ETM TELESCOPE
First article ETM telescope has been assembled. The preliminary alignment
and focus looks okay using visible light. A final test will be done
at 940
nm. A bid package was sent out for production quantities, and we are
expecting quotes by 6/16.
PO MIRRORS
The 80 pitch adjustment screws for the 2K PO mirrors galled when the
parts
were cleaned and baked. The SS screws are being electropolished to
reduce
the diameters slightly, and will be tested again before shipping to
LHO for
clean and bake and installation in BSC7. A 40 pitch screw with looser
fit
will be used in the remaining 4K PO mirror mounts.
CAVITY BEAM DUMP
Some of the parts for the cavity beam dumps have been received. All
of the
remaining parts for installation in BSC8 are expected 6/15. After a
first
article check, the parts will be shipped to LHO for clean and bake
on 6/17.
The beam dump parts for BSC4 are expected the week of 6/21, and will
be
shipped to LHO for clean and bake during the week of 6/28. The
AR coated
glass for the plate beam dumps was received at LHO. Craig C. is expected
to
complete the remaining top assembly drawing for the beam dump installation
on 6/15.

1. Electronics Rack:
The internal wiring has been completed and the computer has been installed.
The pneumatics were started this week, however will not be completed
until
next week. The AC and grounds need to be connected, at which
time, the rack
will be powered up for the first time. Hytec will begin debugging
the rack
electronics at that time. The pneumatics will be completed and
installed
at the earliest possible time and final debugging will take place.
2. Scissors Tables:
Hand Precision is continuing on the scissors table assembly for the
April
and May delivery. April's shipment (8 tables) will be delivered later
this
week and May's (8 tables) is expected the week after.
3. Fine X-Stage:
Hand Precision has begun machining the smaller components for the Fine
stages. The flexures have been completed and are being stored
at Hand
Precision. The primary weldments (top and bottom) have yet to
be machined.
The scissors table are still using the CNC machines that will be used
to
machine the fine stages. Once the scissors tables are complete,
the fine

Global Diagnostics System
(Daniel Sigg, John Zweizig)
This week continued to write and improve the LIGO specific ROOT
classes. Have also begun to compose a Technical note describing
how ROOT can be used for data monitor development in LIGO.
Testing of the sine response code continued. It can now successfully
control the excitation engine and read data back data from the network
data server, all in time. Started with the swept sine code and the
triggered time series.
Integrated the ISC115 (digital-to-analog converter) code from
Christine P. into the excitation engine. Works fine and excitation
signals can now be generated in both digital and analog form.
For now the clock signal is derived from GPS, but the 1 sec
synchronization is done in software.
Added some new waveforms to the excitation engine: square wave
with unequal hi-lo ratio, impulse function and a simple constant offset.

Alex Marin has moved back to his high-energy roots.
We thank him for his
stewardship of the PEM and wish him very well!
The Guralp Seismometers are due to ship from overseas to California
today. It should take 3 days. They will be tested by the
distributor
in California, then shipped out.
Completed the installation of the Beam Tube PEM plates and the
accelerometer signal conditioners at Hanford. The proximity of
each one
is at the following doors; Y1-1, Y1-3, Y1-5, Y1-7 and Y1-9. Some
thought is required on how the cables will be protected from being
chewed by the residents in the beamtube enclosure.
At this point all major PEM equipement has been at least ordered. Minor
hardware will be ordered on an as needed basis.

We did an analysis of the Invoice Processing history based on information
provided by Dot.
The chart summarizes the data for the past year and a half. Note that
while the dollar value of invoices processed has decreased, the volume
has steadily increased and shows no immediate signs of abatement.
The last of the monthly CIT status reports (IFIS) have arrived and I am working on my monthly reports. There are a number of loose ends to tie up and very little time to do it, but I'm working on them.
LIGO QA has continued working with R. Weiss, A. Sibley, GNB and others to plan the Livingston gate valve seal replacement activity. The project has approved including in this planning with GNB, doing the replacement work in multiple steps to minimize impacts to either detector installation work or the start of the beam tube bakeout.
No report this week.
Matt Evans has started writing a revised optics/field classes based on the existing time domain modal model. This is to make the code cleaner and to make the standard mirrors capable to handle IOO mirrors.
Hiro is working on the modeler_freq to improve the speed. He also writes the manual of e2ecli.
Conrad Taylor has started working for e2e group. He checked out e2e
source codes from the CVS and successfuly
compiled. He started to analyze the adlib code using GNU profiler,
and review the code based on the profiler output. He
also evaluated the latest SUN C++ compiler , and found that it seems
to comform to the ANSI standard and nay be able
compile e2e codes. Last version could not compile.

* (KB) Developed additional network details for the phase I
LDAS system
to be installed at Hanford next week.
* (KB) Worked with Masha to identify a compilation/linking
problem that
only occurred in her account on Sirius. All indications
point to the
home8 directory failing on the server.
* (KB) Spoke with Kevin Doody of Caltech Business
development about plans
for a Caltech IBM SUR proposal. Later discussed SUR with
Tom Prince and Albert.
* (KB) Met with software developers to discuss status and
issues. Worked
with Phil and Mary on the design of User Commands to the
LDAS. Met with
Dave and Ed to bind Spica services to the linux
workstations. Met with
Phil and Ed to target completion of the spica
sycronization.
* (KB) contacted MathCore about Solaris licensing fee for
Mathematica ->
C++ translator. (Late News: MathCore gave us an additional
25% off
after receiving the order!)
* (DF) Finished writing C++ code to perform translation
between ilwd &
frame formats. Concatenating data objects (such as
adcdata & simdata)
is the only remaining element of the Frame API which needs
to be
completed.
* (DF) This week NIS+ was added to m27 to integrate it into
the network.
I have completed 'converting' my development environment
to use the new
setup.
* (Df) I have recompiled the c++ code using the development
tools on
spica. No problems were detected.
* (XH) created a new <program metadata> table
* (XH) revised GDS and LDAS tables
* (XH) created a new database cit_1 on spica
and loaded data into the database
* (XH) created a new database cit_1 on deneb
and loaded data into the
database
* (XH) worked on frame ilwd file
* (XH) revised GDS and LDAS ilwd files
* (EM) Fixed minor bug in metadataAPI to free STMT handle resources.
* (EM) Reinstalled DB2 client on propus
* (EM) Continued to syncronize software between Solaris and Linux
* (MB) Tested XML parser samples provided by IBM on Solaris platform.
* (MB) Met with Kent, Ed, Dave and Phil to solve problems on
my account.
* (MB) Ported IBM's XML parser to support LINUX.
* (MB) Tested XML parser samples provided by IBM on LINUX.
* (BK) Added another set of forms to the CDS application for editting
configurations selected by a channel search. Have tested
all the forms
and have a few items to resolve. Need to add a way to
add
comments to
the Export file.
* (RW) I have been working on the parser/viewer for LIGO_LW
files, using
Daniel Sigg's files as examples. I have the basic GUI
already, connected
to the IBM XML parser. Now I am figuring out the input:
how to get data
which is encoded, little-endian, etc etc and set up a
chain of filters to
read it.
* (RW) Also the (hopefully) final stages of handing off the
bakeout service to Althouse.
* (PSE) Continued work on job task macros and documentation
of the job flow model. Met with Mary, Kent and Albert
to discuss and direct this work.
* (PSE) Worked on the build scripts for Tcl/Tk for Solaris
and Intel/Linux. Installed Tcl/Tk on KITALPHA
(an Intel/Linux box) consistent with the Solaris
instalation on SPICA.
* (PSE) Discussed use of SSH for inter API communications
which do not require password authentication with
Dave Farnham and Stuart Anderson. Will try to get
this working so that the manager can start/kill
low-level API's as necessary.
* (ML) Joined Phil and Kent on discussions of meta macros
for manager
and obtained a template to start metadata macros.
* (ML) Changed metadataAPI to use the proc style for
metadata so calls
instead of object oriented style.

TclPro complains about over-writing procs in log.tcl.
* (ML) Added getData proc to metadataAPI for returning data sets
for select statements.
* (ML) Tested more sql statements on metadataAPI.

Received confirmation that the following equipment has arrived at the
Hanford
Observatory in preperation for the LDAS install.
2 PCs for linux
FORE 3810 Loaner
FORE 0C3 NIC for Ultra 10
various cables
Hanford: (Christine P.)
All the disk space on the server, rainier, is full. Expecting
more
disks to arrive this week or next. Until then I have asked several
users to delete any unnecessary files from their accounts and I have
been cleaning out unnecessary files in the system directories. I had
to
restore, from the backup tapes, one file that was lost due to the full
disks. Actually, users have been very helpful about deleting
files and
some of the user disk partitions went from 100% full to 58% full in
one
day.
Worked with Ed Jasnow and FORE Systems trying to get a maintenance
contract for the ATM equipment put together.
Moved a GC Sun workstation from the EE lab to the Computer User's room
to accommodate the recent influx of Unix users.
Livingston: (Tom E.)
We are tracking down a PO for a backup tape unit.
Ordered IslandDraw for the Suns.
Acquiring quotes for several software packages, some of which
may be available under Caltech site licenses.

Samantha has spent a little time resolving a few PC issues (mainly finishing
finals).
(Suresh)This week was mainly devoted into backup issues. Monthly backup
of most
servers except spica have been accomplished. Spica (server used at
ldas group)
is currently undergoing full backup with locally attached tape drive.
Daily
incremental backup of spica would be carried on once a new tape robot
system
would be operational with it.
After noticing a problem associated with the system propus, it was
rebuilt with solaris 2.6 and installed latest patches. It is under
investigation
for any unusual behavior.
Restored a number of file/directories from backup and some user account
cleanup.
Received a new tape stacker and after a number of hardware issues (vendor
sent
wrong equipment) it is now connected to a SUN box in working order.
Presently,
working on s/w and drivers to get the backup automation in place. We
are trying
to avoid having to have backups done in a proprietary format.
Received Cadence s/w and licenses. This install is more complicated
in that each
pkg. is installed separately and requires a different procedure for
each pkg.
Should have this wrapped up by next week.
Worked on a number of s/w and h/w maintenance contracts, including the
Caltech
site licensing for the SUN units. Caltechs' ITS group now has taken
over the
responsibility for a number of the site licenses and is still working
out the
bugs/logistics. At this time it appears that we may have access to
more programs
and the Observatories will also have access to more programs. We will
see how
this all works out in the near future.
We have started moving a number of the functions performed on gsparc
to canopus
in order to start phasing out gsparc. Presently, we are in the testing
process.
Barbara created a new active server page for the Amaldi web site for
an abstract
list sorted by session. Made many, many other Amaldi web site
changes
mostly to the Program page.
Continued to set up LSC progress reports as they arrive. Had
problems
with one report that was cut off in transit. Began working on
update to
the LSC MOU web page.

Due to Caltech's conversion to a new Accounting System, there will be a "Dark Period" during which nothing new will be able to be processed. You are encouraged to make travel arrangements for your upcoming trips from now until August or be prepared to purchase tickets using your personal credit card. This "Dark Period" is scheduled to start on June 16th. HOWEVER, I have set my personal goal as close of day on Friday, June 11th, just to make sure I get your trips done. This also applies to Expense checks and Advance Checks. Thanks for your help. With your assistance we should be able to get through this.
Due to the overwhelming amount of new trips I exclusively on the paper work involved for these. I completed 45 new trips (45 Purchase Requisitions and Advance Requests) as well as all the necessary additional arrangements required for them. I still 19 more to work on, with the promise (or threat) that I should expect approximately 10-12 more in the next couple of days. I plan to finish with all the next trips then put my undivided attention to the Expense Report I've received this past week.
Prepared Travel/Vacation Itinerary for the Week of June 7th, 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.

No report as Dot is cleaning out the IFIS system in anticipation of the ORACLE system. We hope to see her soon.
Elizabeth K. Wood
Attended a meeting to discuss the ORACLE training of LIGO administrative staff. We will probably be getting our training up in the Millikan Room during the week of June 21-25. Anyone got any spare computers that won't be needed for a week?
The missing petty cash receipts magically reappeared on Federal Accounting's desk. The replenishment check that I was promised would be ready on Monday is finally ready today. Don't all come rushing down at once.
Continued trying to work with Human Resources and deal with other personnel related issues.
Continue to help Dot with some filing.
