The Project Control Meeting
Agenda for Monday January 10, 2000 will be:
(Meeting time: 10:30 am Pacific Time)
We now have control-room coverage weekdays, from
8am-5pm, with time out for
lunch somewhere in between. We have regular task
lists. Many of these are
still written out longhand in a book, but we
intend get these posted on
a web page.
PreStabilized Laser:
--------------------
(M. Guenther & R. Savage)
A list of all the Washington 2k interferometer fast channels, including
calibration status and location of text files describing the signal
calibration status has been generated and is available at
http://ligo-wa.caltech.edu/~guenther/PslCal/H2_fast_channels.PDF
The text files containing calibration information for the PSL fast channels
are in the directory http://ligo-wa.caltech.edu/~guenther/PslCal
and named
with the convention, signalname.txt. PSL channel calibration
work is in
progress.
Optics:
---------------------
(D. Cook)
Lately I have been trying to make sense of core optic optical lever
readings between the DAQ system results and readings obtained locally
using
a break out box. Also working with a new fixture to make calibrating
them
simple in both in the X and Y axis. Stan, Betsy and I set up a couple
of
cameras to look for the PSL beam when it came time to send it down
the X
arm. ETMx optical lever was checked and put on line for the test also.
When
the gate valves were opened this morning we were
excited to see the beam
hitting the ETMx-2k LOS structure in about the
same location as it appeared
in the Y-arm. It will take some final steering
of the ITMx and ETMx to
bring the X arm on line.
I made some progress in refining some laser safety issues in our documents
as well setting up a facility lock and tag and key storage board which
will
be mounted in the control room. This will help in controlling the laser
safety status of all the buildings and help coordinate these activities
within the control room. We have restocked our class A and B clean
tools
and hardware used in the Optics Lab and for installations. The Optics
and
Vacuum Prep Labs underwent some cleaning and organizing as well.
Core Optics Support:
--------------------
(B. Weaver)
During the short periods of work over the last few holiday weeks,
Nergis has taught me how to measure the Qs of the internal resonances
of the the large optics here at LHO. I have been trying to continue
this
work on my own, however finding quiet times around here has been a
bit
difficult. I will be revisiting this task over the next few weeks
as time
allows.
Meanwhile, I received the 4k IO Baffle glass from Hydratech and have
cleaned it and loaded it into the vacuum bake oven with Bartie.
I am awaiting
delivery of numerous COS hardware for the April installations of Beam
Dumps,
Telescopes, Baffles, etc. I am also spending my time manning
the control room
for various periods during the week. As eventual operators, we
have been
studying up and practicing our dataviewer and status monitoring skills.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC1-4K ITMy: Phase 2 of the SEI installation is completed with
the exception
of passing the leak checks on the Expansion Bellows. Three of
the custom
conflat seals leaked, they were changed out and the leak check passed
one more.
The remaining two were again changed and the knife edge of the Bellows
was
honed. The vertex is being pumped down and leak checking will
be done 1-7.
CAS: Cabling and control box installations have been completed on the 2k system.
The quiet/slow period during the holiday was used primarily to clean
up the
LVEA and to stage and prepare parts for phase 3 of the 4K SEI hardware
in the
corner station.
HAM Work:
Received and tested prototype shims for z-pivots and they seem to do
the
trick--are awaiting remainder of shims for rest of z-pivots.
Air Bearing "quick release" hook ups" were installed on all 4k HAMs
(HAM 10
is the only one without)
Computing:
----------
(C. Patton)
Windows95 Y2K patches were installed on the guest PCs in the OSB, LVEA,
and VEAs. All Solaris 2.7 systems were patched with the latest
2.7
recommended, security, and Y2K patches. All 2.6 systems were
patched
with the latest 2.6 recommended, security, and Y2K patches. All
CDS
Vacuum Controls standalone Sun workstations have been upgraded to
Solaris 2.7 and patched. Each PC user at LHO was advised to patch
their
Windows95 for Y2K and Norton Antivirus updates. So far I have
had no
reports of any Y2K problems.
The PR for the Sun maintenance contract has been sent for processing.
I
am now starting to work on the quotes for the ATM maintenance
contracts. Purchased more cables, hubs, and miscellaneous supplies.
Continued network security maintenance, did the usual backups, helped
with several printer and PC problems, and kept the GC accounting paper
work up to date.
Controls:
---------
(D. Barker)
All CDS Sun workstations and servers were patched for Y2k compliance.
The planned upgrade of hanford1 from solaris 2.6 to 2.7 was aborted
because Solaris would not provide the update option. It was patched
instead. The only casualties of the year roll over were minor problems
encountered with jdclient and data viewer. These have been fixed.
Possible GPS Y2K problems are not expected until February. We plan
to
upgrade all the firmware before this time.
The main Hanford CDS server and the frame builder's minute trend data
are now being backed up every night at 04:00 using the cybernetics
tape
robot. The backups are performed using my PERL scripts, Cybernetics'
robot control software and AFA backup software.
The 2X5 DCU is still having data readout problems, I am currently
working on this.
The MX Video system has been installed and tested. The EPICS video
system has been modified to support MX cameras. Also, the EPICS optical
lever signals from MX are now available and being written to DAQ frames.
The MY and EY DAQ systems have been brought online. Fast PEM signals
from these locations are now available.
Supporting LLO installation of new Sun workstations, ATM and the video
system. Programmed and shipped mv162 CPUs to LLO for IOO EPICS.
Physics Environmental Monitoring:
---------------------------------
(M. Lubinski)
We have had to send 2 RGA controllers back to Pfeiffer Vacuum for repairs
to the power supplies and QC controller card. It has come back
repaired and
is back in service. Pfeiffer is not sure what caused this.
We are
continueing with equipment installation and testing
BSC#4 (West end station): Installed all SEI stacks, installed all counterweights, installed Kapton cabling, did continuity checks on all cables and connectors, all O.K. Reinstalled dome and door, torqued all bolts to spec. and turned over chamber to the Vacuum group for pump down and leak testing. In process of staging all equipment for the Spring Seat replacement in BSC#3 (corner station). (Rich Riesen)
CDS: Tasks accomplished this week:
1.) Built up the last three Sun stations in the Control Room.
2.) Built (2) - cross-connect panels for the ASC at each ends station.
3.) Built (2) - cross-connect panels for the suspensions at each end
station.
4.) Built (15) - dust monitor breakout boxes for PEM.
5.) Purchased remaining parts for the video installation. Installation
is next week.
6.) Designed laser shutdown system for the corner station.
7.) Work to download facility monitoring to data acquisition system
is ongoing.
(Rus Wooley, Juilien Svoboda)
Bake Oven: We have finished baking OSEM pigtails and are starting
a stainless load with an assortment of dogs and flanges.
Computers: We have installed and are using the new Sun E450.
We are also using it to rebuild some software packages for Solaris 7. (Tom
Evans)
PSL: Cabinets have been installed in the PSL enclosure to organize
various components. The PSL enclosure has also been cleaned. Anodized aluminum
tubes have been placed as protective covers in the PSL beam path. The Pre
mode cleaner is still showing drift over time. A different pre
mode cleaner may be installed. IO optics are being put on the PSl table
by Dave Tanner and Sani Yoshida. (Joe Kovalik)
Beam tube bakeout: We are in the process of making the final RGA measurements on the X arm and thing look good at this point. Data is being sent to Rai for analysis, and if all continues to go well we will open the mid point gate valve today (done!), and do an accumulation on the entire X arm tonight. We are almost finished with preparations for the start of the Y-1 bake, and should start in the next week. (Allen Sibley)
Optics: The MMT-3 and RM were installed and aligned during the week preceding Christmas. Joe Kovalik has been monitoring the optical levers and has been recording movement in the RM, in particular a gross change in yaw of about 2 degrees. More time than planned was spent on the RM, especially relocating the optical lever piers and tracking the subsequent movement of the optic. We noted problems with a batch of aluminum pam brackets in these optics, and substituted PFA 440HP (plastic). These too were out of spec, but we selected the best of the batch and completed the installation. In light of the pam bracket problems, I've spent this week working on a couple modifications to maintain concentricity and reduce backlash and we're planning to have a fix for the ETM-y optic. Meanwhile, we're scurrying to stage for the ETM-y installation as well as the ETM telescope the week of Jan 24. (Jonathan Kern)
IOO/PSL components (except EOMs and two folding mirrors to be placed behind the periscope for sideband monitor by an optical spectrum analyzer) were installed on the PSL table, with the assistance of Anthony Rizzi. Two regular (non Brewster) polarizers are temporarily placed before and after the EOM chain. The beam has been roughly aligned till the motor driven corner mirror (the one after the third mode-matching telescope lens).Measured transmission of the SM (steering mirror) as a function of the angle of incidence. The results are as follows:
(S-polarization)

(Sany Yoshida, Dave Tanner)
GRASP Took another weekend of seismic data on three channels
from south end station. Szabi and I successfully generated a modified chirp
and injected it and took runs at three different intensities. Started analyzing
chirp inject data and there appears to be a problem with two of thechannels...looks
like it did not recieve. All instrumentation was taken down duriing Christmas
holidays because of planned work at south end station by Russ and others
during that 1.5 wk period...Plan to troubleshoot two bad channels...
Weather Stations 90% of parts on order for next two weather
stations. Agreement reached with LSU on two new weather stations for next
couple
years. The agreement for the first weather station firmed up. In process
of getting written agreement. James Phinney to come out to discuss pad
placement. CDS arrangements being made to put GC connection at end stations
so weather info can be on web as with first station. LSC modeling.
Modelling: Gathering data on LSC recycled Michelson test...

(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
LHO Commissioning (Stan W, Bill K, Nergis M)
--------------------------------------------------------------------
We continued to search for potential line noise makers in the
PSL and mode cleaner control electronics. We were able to eliminate
a few possibilities (pre-mode cleaner, laser intensity noise). We
did, however, find one large source of 60 Hz noise: a ground loop
between rack 2x4 and 2x8 was made by the cable that connects the
MC length actuator output from the MC servo amp (2x8) to the LSC
input on the MC3 SOS controller (2x4). When we isolated that
ground loop using an SR560, we were able to reduce the 60 Hz peak
in the MC control signal by a factor of 10. There is still a few
uV of 60 Hz on the SOS postion monitors, but we are still to
determine if that really drives the mirror position or is just
pickup in the sensors.
(LATE BREAKING NEWS FROM THE LAST 1 HR: the gate
valves on the
x-arm were opened and the beam has been located
on the suspension
cage about 25 cm above and 5 cm to the right
of ETMx center. Once
again the initial aligners adeptly put the beam
in a conveniently
visible place.)
#MZ note: We're 2 for 2!
ISC length control electronics (Peter F, Nergis M)
----------------------------------------------------
We are extending and tweaking our interferometer length control
Simulink models to include recent experience with the mode
cleaner and 2km arm cavity testing to finalize the specifications
of the electronics modules.
ISC fabrication/installation (MZ for Matt Smith)
------------------------------------------
Matt's working on revisions to the ETM transmission monitor
video system and assembly of ETM/ITM optical lever components
for LLO.
IAS initial alignment (K.Mason, M.McInnis)
-------------------------------------------
Procedures and calculations required to align all the 4K optics at
LLO
have been completed. The next alignment will be the ETMy scheduled
for
the week of 1/24.
An alignment laser is being built up to ship to LLO. This laser will
be
used to check the alignment of IOT-1 which was mishandled in shipping.

Lasers and Optics -- J. Camp
(1.2.1.1.2, 1.2.1.1.3, 1.2.1.1.4,1.2.1.1.5)
--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- A new optical configuration for the PSL is currently being setup
in the
PSL Lab. The change is that part of the output of the pre-modecleaner
(PMC) is sampled and used for the frequency stabilization of the 10-W
laser. Previously the sample beam was used for this purpose. In the
new
configuration the sample beam is used for initial intensity stabilization
of
the laser. The photodetectors after the PMC and after the modecleaner
are
still retained. This configuration will be tried and tested in the
PSL
lab, with an eye on performance and ease of lock acquisition being
kept.
- Fabrication of the 35.5 MHz frequency reference cards for the PMC
is
nearly complete, with only the heatsink, front panel and front panel
connectors remaining.
Fabrication of a PMC servo card is near completion too.
- The power amplifier diode current will be controlled under EPICS
some
time this week. Although this feature was planned from the onset, it
has
never been wired up to date. Controlling the diode current will
facilitate control of the output power of the laser.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
LHO 2k (Haisheng Rong, Guido Mueller)
LLO 4k (Sany Yoshida, David Tanner, David Reitze)
-Installed IOO/PSL components on the PSL table. Two regular (non
Brewster) polarizers are temporarily placed before and after the EOM
chain. The beam has been roughly aligned till the motor driven corner
mirror (the one after the third mode-matching telescope lens).
-DLC mount assembly is underway.
-Measured transmission of 1 inch diameter REO HR mirrors in s and p
pol
at 45 degree incidence:
s pol T = 1.4 ppm
p pol T = 236 ppm
in p pol, the transmission increases to 1300 ppm at 22 and at 68 degrees.
The OSA takes its beam through a 1" mirror in p-pol, so using one of
these
mirrors provides about 2 mW for the OSA.
-Measured transmission of the SM (steering mirror) as a function of
the
angle of incidence. The results are as follows:
(S-polarization)
angle of incidence (deg) 25 30 35 40 45 50 55
transmissivity (ppm) 2766 2550 2444 2670 3024 4426 7080
(P-polarization)
angle of incidence (deg) 38 39 40 41 42 43 44
transmissivity (%) 2.13 2.57 2.85 3.51 3.86 5.30 6.16
-PSL/HAM Beamtube ready for installation

Global Diagnostics System (Daniel Sigg, John Zweizig)
--------------------------------------------------------
Since the last weekly report I have completed the rewriting
of the trigger and LIGO_LW report generation classes.
Documentation for these classes has added to the web
documentation structure. A new version of the DMT software
was tested, released, installed and (oops) debugged on the
DMT machines. This version contains several added features
(including the new/modified classes mentioned above) bug
fixes and numerous changes made to ease installation on
other platforms. I also made and documented a few small
changes to the channel monitor requested by Dave Barker
to improve usability.
Added the possibility to use the diagnostics test tool on
already recorded data (of course without stimulus). This
seems particular useful for power spectra estimates and
correlation studies. As it turns out the speed of reading
data from the disk is about 3 times faster than real-time
independent of how many channels are asked for.
Received the 2nd gigabit ethernet hub and installed it in
place of the unit which broke late last year. Continued to
work on calibration issues (definition of record format and
client-server protocol for data clients in the control room).

* (BS) Alfi 4 Software Development: (3.5 days)
- Tracked down an elusive timestamp problem which was interfering
the saving of Alfi box files. Some work remains
on the issue
as there are multiple ways to open an Alfi box,
and the other
methods will have the same problem. Considerably
shorter work,
though.
- Continuing systematic exercising of Alfi 4 features to determine
where work is still needed for release. Completed
the first set
of tests and am working with Ed on making fixes
to bugs found.
Hiro Yamamoto
* Looked into the systematics errors of the frindge analysis,
but it was
found that no analysis bias can explain the variation of the
front
mirror reflectance.
* 3d mirror module based on Malik's code is developed.
* Received a preliminary FFT analysis paper from Tomaru of TAMA.
This
will be distributed to interetsed party.

[Kent Blackburn]
* (JKB) Attended a teleconference with Kirk Jordan of IBM's
academic support team to
discuss potential areas where
LIGO and IBM could collaborate.
The focus was more in
areas of software than past
interactions with IBM with
one key area being DB2 activities
being undertaken by
the LDAS group which fall
outside IBM's support group
and more in line with research
efforts.
* (JKB) Attended a teleconference with LDAS dataConditioningAPI
colleages in Australia,
UTB & PSU to discuss functional
requirements for algorithms
to be integrated into the
dataConditioningAPI. Focus
was on issues of FFTW, mixers,
and statistics algorithms.
* (JKB) Attended a non-disclosure meeting with Sun to hear where
Sun technology was heading
and how it might benefit our
LDAS (and other LIGO) efforts.
* (JKB) Met with Alex and Phil to discuss a improved frame reader
method to the frameCPP which
will also be used as an extension
to the frameAPI. This improvement
is based on a similar writer
method added by Alex to
speed up the framebuilder.
* (JKB) Met with Masha to outline the definition of frame and ilwd
concatenation operations.
* (JKB) Spoke with Alan Wiseman about the status of the LDAS database
(both server and client)
components and how they could best be
utilized in the planned
mock coincidence proposal.
* (JKB) Called two separate meeting with the software staff this
week where the discussion
focused on status and future
tasks as we push hard for
getting out an alpha release of
LDAS in the next few months.
Other issues include enhance-
ments to the LDAS web pages
and server; configuration of
the CIT LDAS system; reassigning
tasks left open by Grace
Hu's departure; status of
upgrades associated with the
IBM DB2 5.2 to 6.1 migration;
enhancements to the frameAPI
to improve performance;
and current documentation practices.
[ Phil Ehrens ]
*(PSE) Rewrote all structure accessing functions in frame.tcl
to use the new efficient functions
in libframeAPI.so.
*(PSE) Discussed (with Alex and Kent) modifications to
framecpp.so to support optional
"mapping" of frame
structures to increase efficency
in accessing multiple
frames with identical structure.
[Alex Ivanhov]
* (AI) completed frameAPI performance code documentation

[Mary Lei] 12-23-1999 -> 01-06-2000
* (ML) Worked out an acceptable syntax for creation of trigger
for sngl events to delete
associated sngl_datasource
and sngl_transdata. Split
creation sql scripts into
create table and create
trigger scripts since create
trigger uses db2 -f command.
* (ML) Created db2 script xrefs.sql to extract referenced
data from tables such as
process, filter, frameset etc.
Created tcl script xrefs.tcl
to convert xrefs.sql
output into .h files for
including in ilwd.
* (ML) Updated ilwds to use include file as data to avoid
updating referenced data
in ilwd each time we need
to insert at a site.
* (ML) Replaced llo database with new tables and populated
it with data from ilwd.
Measured insertion rates.
Adjusted sql and tcl scripts
to keep ilwd unchanged.
* (ML) Start looking into implementation of Peter's way of
submitting ilwds: multiple
tables in an ilwd.
* (ML) Created new tables at CIT new metaserver machine.
But need IBM odbclib and
log directories before
data can be inserted.
* (ML) Revised ilwd generation source code to handle multi-table
ilwds according to Peter's
test scenario.
* (ML) Working with Ed on connecting metadataAPI to cit metaserver
with IBM db2 6.1.
* (ML) Updating LDAS db2 document web page for new tables and
new ilwd and xml examples.
[ Edward Maros ]

Lazzarini:
Circulated draft release -06 of the LIGO/VIRGO frame specification for review by various interferometer groups.
Lazzarini, Finn, and Mours drafted a task definition list for the GWIC Joint Data Analysis Working Group. List will be edited and circulated among GWIC members in the near future. It lays out the tasks needed to be completed to embark on a network-based analysis of multiple interferometers (and bars).
Drafted a technical note for publication on how the rotation of Allegro bar detector can be used to modulate the GW background signal and thus identify non GW sources of correlated background signal.
Contacted our PNNL points of contact regarding eventual upgrade of the
LHO internet link. LIGO will particiapte in future planning discussions
among DOE and local carriers in thE PACIFIC NORTHWEST to determine
how to proceed.
LDAS Hardware:
(EFM) Added Susan Scott and Philip Charlton as CVS users.
(EFM) Installed DB2 v.6.1 on metaserver.ldas-cit
(EFM) Added entry to automount frame archive for frame
clients.

Stuart:
Finished installing and configuring all of the Caltech LDAS
installation computers. Arranged and attended a meeting with Sun Microsystems
to present non-disclosure information on their upcoming hardware and
software products that are applicable to the mass storage needs
of LIGO.
General Computing
MIT:
Nothing to report
Livingston:
We have installed and are using the new Sun E450. We are also using
it to rebuild some software packages for Solaris 7.
Hanford:
In the process of upgrading the server to Solaris 2.7. Loaded the latest
patch
cluster and fixed e-mail problems.
Windows95 Y2K patches were installed on the guest PCs in the OSB, LVEA,
and VEAs. All Solaris 2.7 systems were patched with the latest
2.7
recommended, security, and Y2K patches. All 2.6 systems were
patched
with the latest 2.6 recommended, security, and Y2K patches. All
CDS
Vacuum Controls standalone Sun workstations have been upgraded to
Solaris 2.7 and patched. Each PC user at LHO was advised to patch
their
Windows95 for Y2K and Norton Antivirus updates. So far I have
had no
reports of any Y2K problems.
The PR for the Sun maintenance contract has been sent for processing.
I
am now starting to work on the quotes for the ATM maintenance
contracts. Purchased more cables, hubs, and miscellaneous supplies.
Continued network security maintenance, did the usual backups, helped
with several printer and PC problems, and kept the GC accounting paper
work up to date.
CIT:
Barbara worked with Linda Turner to try and resolve problems with duplicate
document numbers. New fields and additional edits will be added
to the
application to lower the risk of this happening again. Discovered
the new
y2k sort fields for document number and document year aren't always
being
created when a document is added. So a fix for this will be installed
too.
Continued to work with the Digital Media Center on the inauguration
videotapes. They are encoding the Friday segments. Larry
is in the
process of ordering the media server hardware.
Made web site changes to the LSC, undergraduate student, and
conferences/committee meeting pages.
Worked a little bit on the web form to upload a document to the DCC.
Ed performed a full backup of Spica and is working with Suresh on setting
up the
SUN 450 for use by the programmer.
Sam is back in school but is continuing her work on the documentation
of the
computer layouts.
Larry is working a number of procurements including: New PC's for web
services,
projector for the conference room, lap tops and periphrals, computer
and network
switches, racks for the beouwolf systems at the observatories and other
assundry
items.
Working on a number of maintenance contracts. Starting with FORE and
Applix.
Also reworking the license problems with SDRC IDEAS masters series.
We have to
go through the full process again to resolve the problems with the
licenses.
Suresh completed th monthly full backup of servers before new year to
make sure
that Y2K may not any adverve impact on data.
Making new backup print server (kuma). The idea is to separate print
and mail
services currently running on acrux so as to downgrade overhead in
acrux.
Installed an ATM card in Kuma which is currently being used for doning
full
backups.
Working on to buy a external tape drive unit.
Set up new user accounts. Assisted users for their problem.
Rita Torres
No report due to illness.
Irene Baldon
Worked on preparing the paper work for 20 new trips taken recently or upcoming (20 Payment Requests and 8 Advance Requests). There are approximately an additional 21 new trips in various stages pending completion of travel arrangements before the paper work can be completed. Also worked on an unusually high number of problem issues which required a good portion of my time.
Completed 35 Expense Reports, some of which were extensive, involving 2-3 or more pages each. Some of these reports were still not taped or completed by the Traveler, and required additional time for completion. Worked additionally on a number of problem issues associated with these which required a good portion of my time. There are 19 Expense Reports still to be done. I'm holding 6 completed Expense Reports which require a check from the Traveler before sending to Travel Audit to clear.
Rita and Liz were able to complete 9 Expense Reports for me. They have no Expense Reports in the process of completion. Thanks Rita and Liz.
I have not seen any significant change in the time lag for receiving checks nor have I started receiving T numbers for the trips prior to or during the duration of the trip. I continue to receive T numbers after the completion and pay off of the Expense Report.
Performed normal recording and filing associated with Travel and Reimbursement.
Prepared the Travel/Vacation Itinerary for the Week of December 20, 1999 and January 3, 2000.
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.
Dorothy Lloyd
Three-day report: I returned from vacation to a heavy load of invoices to process for payment. Monday and Tuesday were spent processing these invoices both on- and off-line. Incoming requisitions were entered and approved on-line on Wednesday.
Jim continued working on reconciling status reports (June '99, which will complete the year) and data entry into LIGO database. He also got in some miscellaneous filing while I was on vacation.
Elizabeth K. Wood
I've been on vacation. However, while on vacation, I turned a Framemaker
paper of Albert's into a LaTeX version; found keys and assigned an office
for Jon Johnson, a new employee; answered payroll questions for Joann (thank
you, Joann); and arranged meetings for a BBC interviewer who wants to talk
to some LIGO-related personnel.
