The Project Control Meeting
Agenda for Monday October 11, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #59, consisting of one HAM and two
BSC
bellows, was released earlier this week.
Load #60, consisting of two PSL Reference Cavity assemblies, is currently
vacuum baking and should be released tomorrow, 10-8-99. During
the
routine inspection prior to vacuum baking, one cavity was found to
have a
damaged knife edge on one of it's two rotatable conflat flanges.
Load #61 is to consist of the remaining PSL Reference Cavity assembly
components.
Vacuum Bake Oven B (small parts, i.e. nuts & bolts etc) was leak
tested
last week and was found to have a leak coming from a flange which may
have been distorted when welded.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC Work:
First BSC chamber in the corner station had its Flourel Seats/shims
replaced (BSC4/Beamsplitter). This went fairly well; exposure
time for
the Flourel items was between 4-6 hours (humidity readings fluctuated
between 5-25%) during this work.
Mark G. has been busy getting the CAS system ready for BSC7. We
are
awaiting installation of air lines and a little bit more cabling.
HAM Work:
On HAMs 1&4 we are working on getting the Support Tubes connected
to the
Crossbeams.
Instrumentation Work:
There was a seismometer data run over the weekend at both LLO and LHO.
Unfortunately, both runs couldn't be done at the same time; will
work
some bugs (actually very easy adjustment) out on the software side
and
give it another try in the near future.
Computing:
----------
(C. Patton)
Several new PCs have arrived and are being setup. Continuing to
clean up
after the hacker. No new attacks in over a week.
All of the CDS Sun workstaions being used in the LVEA, Mid and End
stations for Vacuum Controls and general CDS are being upgraded to
Solaris 7. The latest version of the Vacuum Controls software
is being
downloaded for standalone operation in the event the network is lost
between the buildings.
Did the usual backups, ordered more supplies, added new user accounts,
helped with several printer and PC problems and kept the GC accounting
paper work up to date.
Seismic installation: BSC#5 Y-arm end station: Completed seismic
installation, pumped down, leak checked, no leaks.
BSC#2 Corner station: Removed suspected leaky bellow and gaskets, replaced
with another bellow with new gaskets, torqued all bolts per procedure.
HAM#1 Corner station: Staged all tools and equipment for spring seat replacement
and electrical cable installation to begin next Monday(10-11-99). Started
electrical cable build-up for HAM#1. (Rich Riesen)
Optics: Completed both new fixtures to assist Sany in optic preparation. Selected and ordered a milling machine and toolroom lathe for the shop, as well as a few additional small tools. Completed a dash1 version of LIGO-to-go (a small, cheap, Michelson interferometer with an audio amplifier) for Mark. Everybody who sees it wants one for their school, so we're working on a stripped down model for schools. Assisted Sany and Dave Tanner in setting up CIT's 126 in the optics lab for bulk and surface scattering tests into OSEMs. As time permits I'm working on some suspended optic mock-ups for the dedication. We're planning to display 3" and 10" acrylic dummies. Shuttled 5 of our 7 vehicles to town for service. Still waiting on a ball lead screw and powdercoating to complete the straddle fixture. (Jonathan Kern)
PSL: Peter King, Rich Abbot and Virginio Sannibale are here this week and next to continue with the PSL installation. A new frequency stabilization board has been installed and it seems to work well for an external pockels cell, but not for the internal one in the laser box. This is being investigated. (Joe Kovalik)
CDS installation: .Satellite modules for the SOS should begin arriving next week. We are ordering parts for 1X4 (IOO). That rack will be built up here instead of assembled components being shipped from Pasadena. (Rus Wooley)
We are continuing to increase the electrical components inventory in the Lab. Some of them are close to empty. Continue to make cables for Satellite modules. So far more than two thirds are done. Start to prepare the software installation for PEM. (Juilien Svoboda)
Bake Oven: We have installed the bake oven extension and pumped it down overnight. It has come down to the low 10-7 Torr range, and looks good. We are in the process of rewiring the thermocouples and heating blankets, with much help from Kerry Stiff. The last load (a LOS) did not pass, and has been removed. (Inspection after bake visibly showed an "eruption" of trapped material from a welded region.) The next load, which will also be a test of the extension, will be several more LOSs. (Tom Evans)
Computers: We have received and installed an additional 18 Gb disk. (Tom Evans)
Bem tube bakeout: Removal of bake equiptment from the x-2 module
continues. We have removed all of the cryopumps and replaced the blanking
hardware. All ports will be leak tested by the end of the day and we have
baked 5 ports. The electrical contractor (MMR) has removed most of the
DC cables and is staging them on X-1. Demco is in the process of connecting
power and should be finished
early next week. All of the data collection cabling has been moved
to x-1. (Allen Sibley, Kerry Stiff)
SOS: We tested the test suspension tower that we suspended a
spare steering mirror last week. We first investigated how much we could
naturally damp the mirror using a HeNe laser as an optical lever and a
centroid sensor. The HeNe beam was leveled to the optical (granite) table
at a height of 145 mm above the table surface and the centroid sensor was
placed 227 cm from the surface of the suspended mirror. When the optic
was naturally damped, the amplitude on the sensor was typically 0.5 mm
(peak to peak) or +- 0.11 mrad. Then we used the servo loop to damp the
optic further. By selecting the gains properly (by try and error), we could
minimize the amplitude of the optical lever on the centroid sensor as low
as 0.2 mm peak-to-peak or +- 0.022 mrad in the vertical direction (pitch),
and 0.1 mm peak-to-peak or
+-0.011 mrad in the horizontal direction (yaw). We checked the scattering
of 2" optics. We cleaned eight of them and check scattering using a YAG
beam. (These optics were already checked for scattering at Caltech about
a year ago. It was concluded at that time that
these optics had some scattering but not near the center. This time
we double-checked this result). Two of the eight optics showed considerable
scattering at non-central locations. We will not use these two. Other two
showed much lower scattering than the others. We will use these two least
scattering optics for the injection mirrors to the mode cleaner. We have
some more 2" optics in stock, and will do the same scattering test for
these optics after we clean them. (Sany Yoshida)
Suspension: Sany and I aligned the OSEM's. We successfully adjusted
and operated the suspension servo; the optics damped to within some fraction
less than the quiesent no-servo state. Sany and I developed a way of thinking
about and analyzing the suspension coupling problem. We started the process
of trying to decouple the various lab basis in the lab. We tried the centroid
detector to measure pitch and yaw basis components and tried the dynamic
signal analyzer to look for eigenmodes of suspension/mirror system. We
were able to put the test signal into our current pitch input configuration
and show that the signal coupling to yaw is low (<5%) with current settings
(did
this with signal analyzer method).
LSC modeling: Trouble shooting problem involving feeding back
to ITM vs ETM.
LSU: I gave tour of LLO to LSU graduate students and couple professors
on Tuesday Sept 28th. (Anthony Rizzi)
Environmental monitoring: We have concluded our seismic monitoring this week after about a 10 day run using a grid spacing of 2.5 miles with a 4 seismometer array. One of the seismometer data acquisition units appears to have malfunctioned, and one had intermittent problems, but there is significant data from three of the units over the 10 day period. The seismometers and data acquisition systems must now be returned to New Mexico Tech, but we hope to participate in their loan program and repeat these measurements at a later date. The data has been dumped onto our system and will analyzed to look at correlations at various frequencies, along with earlier data taken at 5, 50, and 500 meter spacings. We plan to estimate the gravity gradient noise using this data.
Community Relations: We received a nice thank you note from Boy
Scout Troop #80, Livingston, for the recycled aluminum cans we have been
donating to them since last April. This has enabled them to purchase camping
equipment and partially offset the costs of sending local scouts to summer
camp.

--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- The reserve intensity control actuator (a 200 MHz acousto-optic
modulator (AOM)) has arrived. The AOM was ordered prior to knowledge
of the
current shunt actuator on the newer lasers. In the event that the current
shunt proves to be difficult to control, the AOM will be used as a
backup.
- A new frequency servo card has been installed at LLO. The new card
basically maintains the same loop shape as the one deployed at LHO
but has
some convenience features added and has an integrated high voltage
amplifier to drive the phase-correcting electro-optic modulator (EOM).
The laser was locked to the reference cavity with the new frequency
servo card using a phase-correcting EOM located outside the laser.
Varying
the gain sliders resulted in the expected behavior. The phase-correcting
EOM located inside the laser will be tested next.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
LHO 2k (Haisheng Rong)
- OSEM study: Data from a series of calibrated measurements on OSEM
responsivity to axial displacement (along the sensing direction) and
transverse displacement for various OSEMs has been sent to Peter F.,
who
is coordinating the OSEM study.
- Diagonalizationm of small optics local controls using internal signals
further reduced cross coupling, still not perfect.
LLO 4k (Sany Yoshida, David Tanner)
- David Tanner is at LLO for SOS preparation.
- An optical lever/quad sensor was set-up for leveling and cross
coupling minimization.
- the scattering of nonsuspended in-vac 2" optics was rechecked. We
cleaned eight of them and check scattering using a YAG beam. (These
optics were already checked for scattering at Caltech about a year
ago.
It was concluded at that time that these optics had some scattering
but
not near the center. This time we double-checked this result). Two
of
the eight optics showed considerable scattering at non-central
locations; these were rejected. Two had essentially no scatter; we
will
use these for the injection mirrors to the mode cleaner.
Mechanical Design (Dan Dickrell)
- Glass for the in-vac beam dumps has been received by UF. All of the
components will be shipped to LHO for vac. prep.
- Incorporatiing Rick Savage's beam stop into the modified PSL-HAM
beamtube design for LLO,LHO 4k
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Metrology continues on 4KITM03, scheduled for shipment at the end of
Oct.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
A total of four 4k ITM's and one SPETM were characterized for scatter.
All
of them showed less than 2ppm of defect scatter.
Scatter measurements are continuing on ETM's.
4ITM02 will be pre-cleaned at Caltech to be sent to Livingston early
next
week.
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE
About 95% of the parts for 12 production PO telescopes have been received
and one unit is being assembled by Ken M. Remaining parts will be delivered
by 10/11.
ETM TELESCOPE
Denis Rose has calculated the focal distance and fixed lens spacer
length
based on the as-manufactured lens data. The manufactured spacers will
be
modified accordingly. A first article set of production ETM telescope
lens
barrels was received and the lenses have been inserted and are awaiting
an
alignment test at CIT.
STEERING MIRRORS
50 sets are awaiting assembly at CIT.
PO MIRRORS
The purchase order was let for the 4K LHO and 4K LLO PO mirror mounts.
VACUUM WINDOW
One of the COS vacuum windows was slightly damaged during shipment
from LHO
due to inadequate packing. Betsy Weaver is evaluating the damage. Widows
will be installed in HAM10 by 10/8.
ARM CAVITY BAFFLE
All of the first article parts of the Inner baffle assembly have been
received and are being assembled by Paul K. The remaining detail drawings
will be finalized on 10/8 for the outer support frame assembly. A purchase
order will be placed by 10/13. Paul K. is working on the top assembly
drawings for LHO and LLO, and the hardware list.
CONICAL BAFFLE
First conical baffle was received by Betsy W. Fabrication of the remaining
production baffles is in process.
COS ALIGNMENT PROCEDURE
Received the anti-reflection coated COS autocollimator, and the second
IR
TV camera with monitor and tripod. Video camera lens is due this week
(10/8). Awaiting delivery of Spare 940 nm and 990 nm laser diodes.
Received
the alignment target for the FM mirror, and the COS autocollimator
bayonet
mount adapter for the ISC Brunson tripod. Mike S. is completing a write-up
of the revised alignment procedure. Using a makeshift laser illuminator
adapter, Mike S. demonstrated that the projected reticle pattern can
be
viewed on a target at a distance of 140 ft using the IR TV camera with
approx. 10mW 940 nm laser power. This should allow a substantial margin
of
available laser power to account for additional losses due to COC mirror
transmissivities and reflectivities at LHO. Ken M. has designed a proper
illumination adapter, and it is being made by the CIT shop.
4K IO BAFFLE
The purchase order for the 4K LHO and 4K LLO IO baffles has been let.
4K ELLIPTICAL BAFFLE
The purchase order for the 4K LHO and 4K LLO Elliptical baffles has
been let.

1. Hytec Hardware:
The next shipment to Hanford is scheduled for tomorrow. It will have
all the remaining cables and junction boxes, electronics rack, actuator
sets, motors, and other miscellaneous hardware left at Hytec.
2. Spring Testing:
18 boxes of springs (648 springs) are yet to be tested. Hytec were
unable to sustain the testing last week because of limited resources,
but will resume the testing next week.

Global Diagnostics System
(Daniel Sigg, John Zweizig)
I continued to look for the error found with large frames.
Suspecting that the frame data received by the consumers might
be incorrect, wrote a Frame test monitor that verifies the frame
structure independent of the frame unpacking software. This
hasn't found any errors, but neither have the other monitors died.
This continues to be a concern, but is on hold until the errors
reappear.
During the investigation of the data distribution, I noticed an
anomaly in the buffering scheme. I repaired this and added
some additional functionality while I was at it. As a result, the
monitors should get all incoming frames more reliably without
reserving buffers.
Added an EPICS channel access interface to the diagnostics
test software, so that tests can set epics channel (e.g., gain
settings) prior of execution.
Made the test point manager aware of the second interferometer.
Started debugging the (multiple-)sine response test.

-------------------------------------------
PSL (Rich)
===========
1. Finished installation of new frequency servo card and after some
confusion about the internal pockels cell in the amplifier. The new
servo
performs as expected and as soon as the pockels cell has been realigned
we
will begin to characterize it.
2. While the realignment of the pockels cell is in progress, the VCO
is
under scrutiny with a goal of accurately determining the phase noise.
The
results will be compared with the recent noise plots obtained from
the
modecleaner lock.
3. The premodecleaner servo card is standing by such that as soon as
the
frequency servo dust settles, we can commission it using the newly
installed piezo. This will probably happen next week.
WA 2K One Arm test - LSC: (DAO)
===========================
LSC photodiodes: We have tuned 3 photodiodes and things look good with
the
new
design. We are still trying to understand the calibration using the
small
laser we
have now. Using the test input we get about 280 Ohm impedance on the
resonant
circuit or 2.8K transimpedance at the output. This is about what we
expect
from
modeling. We have yet to get reliable and believable results using
the
laser. We
will continue to sort that out. Meanwhile, we will send one to MIT
for them
to measure.
I & Q Demodulator: Done (Rich)
Servo Amp: Done (Jay)
Notch Filter: One board is assembled and ready to test.
Photodiode Interface: The design is completed for a four channel board.
PCB
Layout in progress.
Eruocard Slot Tester: Circuit design is almost complete. This is a
general
purpose
test card for testing the cabling to the EuroCrate via an EPICS Screen.
Rack 2X1: The wiring diagrams are complete (Jay). The wiring harness
is being
wired this week. I will be in Hanford next week and can install it.
EPICS Screens and Database Records: These have been started (Mohana).
Timing System: (DAO)
=====================
GPS Clock Driver: There is one installed at each site. Six more are
being
assembled now. I will test them when I return from Hanford.
GPS Clock Fanout: Ten are in the field. We are about to make a production
run.
GPS Antennas: Six spares are on order.
ISC Clock Fanout: Four have been shipped to Hanford. Six more are in
the Queue
for assembly.
Suspension (Jay)
=================================
- 10 satellite amplifiers have been assembled and are ready for test.
Tests
are
on hold for manpower.
- A preliminary design for a satellite amplifier that uses a coherent
detection
scheme is complete. This design is compatible with the exisiting suspesnion
controls and will be completed and tested as time permits.
- One possible solution for moving the suspension diagonalization procedure
to
the control room has been developed and can be implemented with existing
hardware. We should be able to get it installed and ready for tests
the last
week of October. This diagonalization procedure relies on the optical
levers to
give an independent measurement of pitch and yaw and is therefore not
applicable
to SOS systems.
LLO IO Controls (Jay)
================================
- System drawings, parts lists, cross connect lists and cable pull
lists
for the
LLO IO controls have been completed and sent to LLO for installation.
LHO ASC and One Arm Test (Jay)
================================
- Cable pull lists for the full 2K ASC system and the one arm test
have been
sent to LHO for installation.
- Cross connect assembly is 95% complete and will be shipped to LHO
next
week..
- Software for the one arm controls has not been started.
- X and Y arm ASC wiring harnesses have been shipped to LHO for installation.

WEBSTER has been available to me for approximately 4 hours during this week. (Either WEBSTER is down, or the LIGO network is down...)
My WEBSTER has black squares instead of +/- signs This problem causes a hit or miss option on whether there is a lower detail on any given expenditure type for any account. I spend twice as much time as before (and that was a LONG time to begin with) trying to make sure that everything is opened to the lowest detail before saving to a file (and I have had to redo accounts because it was not saved with the lowest detail opened - thus taking even longer). Without the visual +/- signs, I spend excess time opening, then closing, then opening the same expenditures trying to find out IF I had already opened it (maybe you have to be there to understand. (Neither LIGO or Administrative Application Support people seem to know why this is or how to fix it. I have a call in to David Werntz and am awaiting his call back.) [NOTE: David Werntz returned my phone call and has just left my office. He has solved my problem and my +/- buttons are all visible. I will supply Larry Wallace with the solution so if the problem comes up again he will know how to correct it.]
Last week I managed to complete the August Construction Summary reports. This week I have downloaded the details for about 10 Construction accounts (out of @ 175). This has been mostly for individuals who have called me requesting specific information regarding their accounts.
When/If WEBSTER comes up (it is unavailable as I write this) I will limit my user time to "summary" only for August R&D and Operation accounts.
Four proposals have been received for security consultant services in Livingston. Those proposals within the competitive range will be given purchase orders to have them come to Livingston as a review board to perform a threat assessment and a comparative analysis with similar facilities in a like environment.
A statement of work is being prepared to acquire design and engineering services for the new Staging Building at Livingston. Proposals will be requested from Parsons and John Desmond Associates in Baton Rouge.

[Bruce Sears]
* (BS) Alfi Software Development:
- Assisting Ed with the building
of version 4 of the Alfi GUI,
specifically
with the box component
tree which will display the hierarchy of
boxes and
primitives in a given
simulation set-up, as well as allowing
quick and easy
access to configuring
them. This week I have experimented with
different
aspects of the wxWindows
library, and inserted the tree control
into the
Alfi4 software.
Currently I am writing up a plan of how to get
the box
and component information
into the tree to show Ed so he has an
understanding
of what I will be
doing.
* (BS) General C++ Education:
- Studying the C++ Standard
Template Library as well as other
parts of the
C++ standard
library (my background in object programming is
in Java, so
much of library
interface is new to me.)
* (MB) Added an error handler for XML parser in lwAPI: thrown by the
XML parser
exception wouldn't get to the
tcl layer without it.
* (MB) Tested lwAPI:
- on Sun at Caltech.
- on Sun at Hanford.
Testing:
- on LINUX at Caltech
[Kent Blackburn]
* (JKB) Installed new video switch between the dataserver and metaserver
at Hanford.
* (JKB) Removed the OC12 blade from the LDAS Fore 1000 ATM switch. The
OC12 blade, OC12 PCI card
and the connecting fiber were shipped
to Livingston today and
should show up (attn: Tom Evans) tomorrow.
* (JKB) Traced the frameAPI's tcl extension, locating the interface
which
is used to create frames
and add attributes to the header. Extended
this interface to include
gpstime, localtime , leapseconds, dt, as
per the Frame Specification.
There is still a bug lower down in the
code which effects gps time
and needs working.
* (JKB) Traced down a performance issue in the writing of the ILWDs
which
was caused by the use of
indentation in the frame ILWDs. This has
been replaced with a version
that doesn't use indentation to slightly
improve the performance.
* (JKB) Identified that the current framebuilder is not writing the
length
of the frame in seconds
correctly. This has been reported to Alex.
* (JKB) Modified the frameAPI's header datatypes to use those defined
in the
Frame Specification. This
only effected three of the tcl commands
used to create frames. Datatypes
have names: {INT_2U, REAL_4, ...}
* (JKB) Attended LSC/ASIS teleconference.
* (JKB) Went through new Hanford SOP training for LIGO 10W laser.
* (JKB) Focused on getting the current version of LDAS working here
at
Hanford. This has occupied
most of the LDAS team this week. Most of
the trouble areas have been
with the database tools. (see EFM & ML).
[ Phil Ehrens ]
* (PSE) This week I have been at the Hanford, WA LIGO observatory
with Kent Blackburn and
Mary Lei working on the installation
of LDAS software on ldas.ligo-wa.caltech.edu
(dataserver).

reside on that machine.
* (PSE) Benchmarked calls in the frame::create procedure, which
is the functional core of
the getFrameData user command,
and identified several bottlenecks
which will need to be
optimised-out in the c++
layer.
* (PSE) Worked with Kent and Nathan to correct errors in the headers
of "reduced" frame and ilwd
files produced by the frame API.
* (PSE) Improved diagnostic and error handling capabilities of the
frame API.
[Grace Hu]
* (GH) Finish reading most of the papers except the Metadata API's
baseline requirements, LDAS Lightweight
Data format specification,
and LIGO Data Analysis System
Preliminary Design. I believe I can
finish them in this week.
* (GH) Setting up computer working environment, this includes setting
cvs
repository and creating private
account in kitalpha server.
[Mary Lei]
* (ML) Worked with Ed on testing the newly created ilwd files
against ldas-0.0.3 and his
metadata shared object changes.
Able to insert arrays for
some tables like ppgeneric.
But not for others with
unique Ids. Had to use openlink sw
since ilwd lib again interferes
with database open.
* (ML) Recreated all tables in hanford lho database since some
relations did not seem to
exist. Ran descMetaData test
to verify all was ok.
* (ML) Installed uniqueId stored procedure on lho_1.
Produced a set of ilwds
for putMetaData after changing
real_4 and real_8 ilwd types
to int_4s. Unable to insert
with real_4 or real_8 ilwd
types.
* (ML) Fixed sql for ringdown and directedperiodic to enable triggers
for event_id field.
Edward Maros
* (EFM) Worked on multiple row insertion problem
* (EFM) Worked on REAL insertion problem
[Nathan Yospe]
* (NY) Ran tests of frame API and libs to find reasons for lost data
* (NY) Rebuilt ldas under linux, sun with new frameAPI, framecpp with
.ccmalloc under linux; running
tcl scripts that load frameAPI
to generate .ccmalloc logs for
memory leak tracking. Working
on getting tcl scripts to function
properly with new function
call sequences.
LDAS Hardware:
(EFM) Rearranged the computer room to make use of racks.
SBA: Continued support for the 40m data run which has uncovered a number
of minor problems in the frame builder software. HPSS has successfully
archived the last week of continuous data with a single 1hour outage
which did not result in the loss of any data since that is well within
the scope of the disk cache at the 40m and the archive process was
able
to catch up with the backlog once HPSS was available again.
I have begun archiving trend frames from the 40m and 2km@LHO at Caltech.
Since the frame files are compressible by a factor of x10 the existing
network
connection to LHO has been sufficient to pull down the last month of
trend data at 3.5Mbit/s (~50GB). The data is currently archived on
disk but
will shortly be pushed into HPSS via an automated script.
Walid Majid
[WM]:
I am continuing to look at the recent 40m data. Have met with
Dick
Gustafson to discuss some of the details of the various interesting
channels including the variant GW channels. I also met with Roy
Williams
to discuss ways to excercise the LDAS database machinery. At
the moment I
am using my own simple and naive database which I wrote.
By going through the dataset over the 3 day period, I have found a couple
of issues that we might want to fix. One is that we have about
7 dropped
or missing frames over a period of about 100,000 seconds. While
the number
is insignificant, it might be useful to findout what is causing this.
My
experience in DAQ tells me that not understanding these kind of rare
events
can come back in other ways to surprise us.
Also, I found that about 0.5% of the data has an incorrect GPS time
stamp.
But the error is always 20.5 msec in these frames, suggesting that
the
timestamp is sometimes written 1024 ADC samples later. Since
the DCU's are
read at 16Hz, this might suggest somekind of delayed response depending
on the state of the VME CPU.
[AL NOTE: Discussions with CDS indicate that
these "features" are specific to 40m DAQS
and are not expected to be issues with LIGO.
Stuart Anderson has started a "sniffer" at LHO
to compile time stamp statistics to verify
this].

- We have received the replacement Sun monitors we have been
waiting for.
- We have received and installed Photoshop on one of the PCs.
- We have received and installed an additional 18 Gb disk for
user files.

- This week is mainly devouted on fixing up email problems we have
experienced. The problem associated with pop mailer deamon (ipop3d) has
been temporarily resolved. Recent
system hacking and rampant virus problems contributed to the erratic
behavior of the email system. Systems being broken into are being investigated.
Some users are
being advised to use alternative systems. This has motivated us to
implement
some kind of anti-hacking infrastructure.
- Routine monthly backup of LIGO servers have been accomplished. Some
new user
accounts have been created. Usual support services have been provided
to users.
B. Kratochwill
- Worked on the second iteration of the LIGO II Cost Book application
in MS Access. There are new table
definitions and forms. I am almost finished with a Level x Detail
report.
- Worked on the second iteration of the web pages for the LDAS
Software Block Diagram. I mapped to a
couple of pages as samples and got favorable responses. There
are a few more to create to finish up the
mapping.
- Tried to help the DCC print the as-built drawings from PSI.
I downloaded an HP printing system with
additional fonts and was able to print the drawings on the HP 5000N
in Millikan. But this solution didn't
work with the NT box and the hpmlrtsn printer in the Bridge Annex.
- Helped with the LIGO II site, helped with the Celebration database,
made a number of web site changes.

For E. Jasnow did two additional letters Re: site security, faxed then mailed these. Did edits to pending contract with Richard Price Constructing for Erosion Control and Landscaping at LLO. Obtained several copies of the document, FedExed along with letter to NSF for further review, and for approval.
For P. Lindquist did a bit more formatting to Draft Cost Estimation Plan. Distributed minutes for CCB meeting of 9/14/99. Ordered more items with the P-Card, and reconciled orders. Did site trip updates for Detector Group.
Collected information on LaserJet Toner cartridges from several vendors to compare prices, ordered several cartridges at the best price. Have started update of PO information for D. Lloyd. Dorothy's "PO Log" facilitates record keeping for the myriad LIGO accounts. Update is ongoing.
Dorothy Lloyd
Continue to enter and approve numerous requisitions in Oracle and running periodic searches to find PO number assignments. Performed "primary" and "secondary" receiving on-line.
Tracked and followed up on numerous invoice problems and processed the usual heavy load of invoices for payment.
Notified various task managers of status of their subcontract funding levels and requested approval for supplementing funds and proceeded with supplementing those with approvals.
Jim continues to reconcile status reports and continues data entry into the LIGO database.

Worked on preparing the paper work for 20 new trips taken recently or upcoming (20 Purchase Requisitions and 14 Advance Requests). There are approximately an additional 33 new trips in various stages pending completion of travel arrangements before the paper work can be completed.
Completed 31 Expense Reports, some of which were extensive, involving 2 or more pages each. Some of these reports were still not taped or completed by the Traveler, and required additional time for completion. I would like to request that staples not be used when attaching receipts to 8-1/2 x 11 white paper. Staples scratch the copier. Also, please do not tape receipts on top of each other. They must be clearly viewed. Worked on a number of problem issues which required a good portion of my time. There are 18 Expense Reports still to be done, including 5 that require extensive work to complete. I'm holding 5 completed Expense Reports which require a check from the Traveler before sending to Travel Audit to clear.
I recently was informed that we will again be given T numbers which enable us to track a particular trip but still have not seen any significant evidence of these elusive items (I received 2 out of many new trips sent through recently).
Performed normal recording and filing associated with Travel and Reimbursement. Travel has yet to be worked out in regards to ORACLE and things are still in a state of extreme confusion. Things change many times from hour-to-hour. It is very difficult to get things through or out of "The System."
Continued making travel preparations for the upcoming LIGO Celebration to be held at our LIGO/Livingston, LA, site on Nov. 11th and 12th. Vee and I have arranged for Conference Rates with two airlines (Delta and United for domestic flights and Delta for intercontinental flights). We have arranged for a block of 155 rooms at a number of hotels in Baton Rouge, LA (75 at The Radisson on Constitution Ave.; 40 at The Amerisuites on Bluebonnet Blvd.; 25 at The Homewood suites on Corporate Blvd.; and 15 at The Hampton Inn on Constitution Ave.). All is in place now and travelers are able to call or e-mail Vee to book their trip using the special rates we have obtained. I will pass on more information as I get it. In the meantime, Barbara Kratochwill has put the current information on the WEB page. Please book your trip as soon as possible. Flights, hotels and car rentals go fast, especially when I understand that approximately 400 invitations have gone out world-wide.
Travel has started for the PAC7 Meeting to be held at LIGO/MIT from Nov. 18th through Nov. 19th. A block of rooms have been reserved at the University Park Hotel (just behind the LIGO/MIT Lab) at a rate of $109.00 per night for the nights of Nov. 17th and Nov. 18th. These rooms are going fast so if you plan to attend the PAC7 please get your trip started with Vee as soon as possible.
Prepared the Travel/Vacation Itinerary for the Week of October 4, 1999.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as from members of the staffs of each of the two (2) sites. I continue to do MIT's travel to the sites for installation activities and assist them wherever possible.

I GOT THE PETTY CASH CHECK!!!!!
Received the list from disbursement audit to confirm where payroll checks get sent. If you get your paycheck on Friday, they have already fixed the problem. If you don't get your paycheck on Friday, I will have to make the proper adjustments.
Dealt with payroll on a variety of interesting issues.
Got the issue of the pinball check corrected. It has now left HR and is on its way to the check producing people. Of course, I'll believe it when a check is actually produced.
Took an ORACLE class in labor account distributions. This is something that only the keeper of PAN forms does and as a result, few of you can relate to this. However, I found that doing retroactive account distributions is akin to calculating the future value of annuities. My HP19B financial calculator was indeed a valuable investment.
Took an ORACLE class in base receiving. Now I know how to receive but I was informed by Dot not to try it.
Attended a meeting of the LIGOfest organizers.
Made several phone calls to IGO, formerly known as 1800batteries to find out why a p-card was being charged for things we paid for back in February and March. After three days' of calling, I finally got a call back. They admit that they might have made one mistake; they're holding judgement on whether they've made two. Many thanks to Criselda in this nasty on-going matter.
Had a lovely chat with Sharon Borbon in the provost's office about the visa situation of several LIGOites. If anyone knows of someone who has a background in immigration law and who would love to work on visas and other immigration-related matters, give Sharon a call.
Spent some time with Cindy observing her problems with WEBSTER and her
personal computer. Computer problem solved; needlesstosay, WEBSTER remains
a difficulty.
