The LIGO Executive Committee
Agenda for Monday January 24, 2000 will be:
(Meeting time: 10:30 am Pacific Time)
Open meeting 10:30 - 11:30
Special Items:
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC2-4K Beam Splitter: As expected, internal SEI hardware installation
has begun and
continues. We have completed Phase2 and began Phase 3 on 1-19. The
first layer of Coiled
Springs and Masses are in place. We should complete the Isolation Stack
buildup 1-20 and
plan to replace the chamber dome 1-21. The installation of counter-weights
onto the Optics
Table will be postponed until the door on either BSC1 or 3 is removed.
Phase 3 (Isolation Stack) of BSCs 1 and 3 will start after the completion
of the same for
the 4K HAMs.
HAM2: The west door was removed to provide access into BSC2 and will
be the first HAM to
have the isolation stage installed.
Computing:
----------
(C. Patton)
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)
Installed samba on CDS system. Upgraded control room pc to win98 and
Excel2000. This can now maintain the installation/calibration data
(files are located on hanford1 and are available through cds web page).
Gave operator training on CDS overview.
Updated the CDS red book (procedures for system shutdown and restart).
Reviewed CDS bug list.
Released MEDM screens for 2k optical lever and suspensions, added them
to site overview.
Working on making jdclient y2k compliant.
IO Optics: We measured RFAM of the three EOMs. They all met the LIGO requirement. We still need to tune the resonant circuit of the EOMs (it has been roughly tuned, but not perfectly). There was a fried trace for one of the power supply voltages on the board of the damping servo control for MC1 which was discovered and fixed. Now all the six small optics can be damped. (Muller, Wooley, Rakhmanov, Yoshida)
OPTICS: Staging for the ETM-y installation is almost complete; we've marshalled everything in the vertex and will spend next week moving it all to the Y-end. We've also cleaned and baked the ETM telescope components, and will lay it out in the Optics lab for Mike Smith and Ken Mailand to assemble next week. I've spent much of this week working with Myron McGinnis to setup and enable the ISC Alignment Laser procedures. Yesterday we received the beamtube and shutter from UofF connecting the PSL enclosure with HAM-1. Its requiring some rework but we'll have it fitted in place and anodized before Dave Reitze begins IO in-vacuum alignment next Tuesday. Increasing amounts of my time are being spent dealing with Laser Safety issues; we're expecting to transition to Laser Hazard in the Vertex early next week. (Jonathan Kern)
CDS Installation: Items accomplished:
1.) We received the equipment required for the IO work scheduled for
next week.
2.) Installed the three remaining LOS controllers.
3.) Installed and tested the laser emergency shutdown system.
4.) Fixed MC1 control problems.
5.) Set addresses on all the VME cards required for IO installation
at the LVEA and suspension/alignment installation ay the south end.
6.) Built eight of the small eurocard chassis.
7.) Rewired three receptacles in the LVEA so that they are now on CDS
power.
8.) FMCS work is ongoing
(Wooley)
CAS: Continuing the buildup of the CAS (Course Alignment System) on BSC#1&2. This is primarily installation of electrical, data, and pneumatic cables, installation of J-boxes, encoders, position sensors, pressure sensors from each BSC to the CAS computer rack. Wiring the Emergency Stop System which daisy-chains BSC#1,2,3 together and to the CAS rack. (Riesen)
PSL: The PSL is shut down until a laser safety incident report
is completed. Peter King is getting a high voltage PMC and its electronics
ready to swap
into the PSl table for mid-February. A laboratory R&D area in the
staging building is being set up for collaborative research work on th
SAS project at Caltech.
Seismic analysis using GRASP Tom Evans and I came up with scheme
for entering channel to be analyzed in grasp in a user friendly way and
implemented it. Did another data run 1/7/99. Found and fixed problem with
DCU (it did not give all chirp injected data--did another data run 1/16/99)...
Ordered and received parts to make permanent interface from computer to
ADC and/or computer (for injecting chirp). Tom Evans built cable for this...
MultifilterF.c has been modified so that it can run LIGO data; I configured
the relevant portion of GRASP and successfully run multiple processes on
a single computer. We are in the process of configuring a second computer
with LINUX to run a two computer test. In process of writing program to
generate mass template for the seismic noise spectrum.
Weather Station Written agreement with LSU completed; getting
ready to formalize agreement. Received towers. Installed new VME crate
in south end station; put weather station ioc in and changed name...brought
up DCU Got the weather station ioc for south end station.
End to End Modeling In process of making block diagram of differential
and common mode of LSC using Final Design Document.
ISC J. Kovalik, Miron and I staged 700mW laser for checking
alignment of IOT1 and pockel cell. Obtained autocad drawings for more of
ISC.
Community relations: 23 girls scouts (2 troops) and their families
came out on Saturday to tour the facility, paint a mural, and have a picnic
lunch. (Wascom)
At the request of an organization of Baton Rouge home Schoolers, the
Ave Maria home schoolers, Anthony Rizzi gave a tour of the Livingston Site
on Saturday, 1/15/99. The kids did an assignment on LIGO which included
drawing a block diagram of the detector. The older children were assigned
a calculation. The children also painted a section of the beam tube as
has become customary for visiting school children. (Rizzi)

Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
Interferometer sense/control (Zucker)
-------------------------------------
MZ is now assisting Jay Heefner in setting science priorities and
goals for redesign of the LOS suspension control electronics. Please
send email to mike if you have issues we should address or want to
be
included on correspondence.
LLO installation (MZ for Myron MacInnis)
------------------------------------------
Evaluation of LIOT1 (which was severely abused in
transit to LLO): No physical damage to the optics is evident
and the
contamination
reported previously has not (completely) migrated to the optical
surfaces. It
looks like the in situ cleaning should be adequate (already done).
Due to an internal ISC miscommunication the wrong IR alignment laser
(a
new dual-wavelength model which has no SOP in effect) was sent down
for
checking alignment; thanks to Joe K. for supplying an NPRO from the
LLO
optics lab in its place.
ISC fabrication/installation (Matt Smith)
-------------------------------------------
This week I worked on updating and releasing drawings to the dcn.
Shipped hardware to Larry Jones for the ETM and optical lever support
piers. Purchased some new items for the ETM transmission
monitors. Sent
out quotes for some machined parts. Sent out the ETM transmission
monitor to Livingston for the Y4k ETM installation.
LHO Commissioning (Rai W, Gabriela G, Betsy W,
David S, Richard McC, Nergis M)
---------------------------------------------------
2 km arm cavity locking efforts continue. Several
more diagnostics of 60 Hz noise wereuring
arm cavity locking runs was that FMy seems to
change its orientation significantly from day to
day. Trend data of the LVEA seismometer and FMy
optical levers spanning those two days revealed
that FMy misaligned by ~180 urad each afternoon
during periods of increased seismic activity.
The FMy optic and controller were tested and the
controller was found to have some intermittently
functioning coil drivers. The optic too has been
found to be pointing at a very skewed angle, but
Gaby has a proposal for dealing with this
in the diagonalization of the sensing matrix.
Gaby has tested her LOS diagonalization
procedure on ITMx and finds it to be well-
behaved (a welcome situation after her painful
diagnoses of FMy's problems).
Amidst all the arm cavity activity we have also
been locking the Michelson interferometer to
measure the internal mode Q's of the large optics.
We have measured some modes with Q's as high as
ten million and some as low as a few hundred
thousand.
We measured the coupling of 1.06 um light from the
laser to the local sensors on the large optics. We
measured the response of the OSEM PDs to intensity
modulation of the laser light incident on the
recycling mirror. A typical sensitivity of 4e-9 W
at the OSEM per watt in the laser beam which would
appear as 36 nm of motion of the optic per watt
incident on the mirror.
MZ: LHO commmissioning addenda 1/20:
---------------------------------
Richard has found several faults in the FMy LOS controller
which are being repaired. It is unlikely that these completely
explain the anomalous misalignment episodes, but
they sure don't help. Should be back online repaired
this afternoon.
MZ is working with Peter King and Rick Savage to
understand and eliminate a nuisance oscillation
of the PSL controls which hampered locking efforts.
G. Gonzalez, D. Cook and R. Weiss are validating
operation of the X arm LOS controllers. This will
permit opening the gate valves to recheck/reestablish
the X cavity alignment.
-------------------------------------------
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
--------------------------------------------
- Both the 35.5 MHz frequency reference card and the pre-modecleaner
(PMC)
servo card mentioned in the previous weekly report have been installed
in
the PSL Lab PSL rack and operated under EPICS control. In shaking
down the
PMC servo, a problem was found with the 35.5 MHz rf photodetector.
For
reasons unknown, the DC output of the photodetector ramped even if
no
light
was incident on the photodetector. The photodetector is currently
being
examined.
- The last remaining high voltage PZT PMC is being prepared for
installation at LLO. After fabrication of a high voltage PMC
servo
card,
both the servo and PMC will be tested and checked in the PSL Lab.
After
tests for functionality, the unit will be shipped to LLO to replace
the
defective low-voltage PZT PMC currently installed in the LLO 4k
INTERFEROMETER PSL.
- Transfer function measurements of the various gain stages in the
frequency stabilization servo card have been made, in an effort to
track down a reason for an oscillation in the servo output to the
phase-correcting Pockels cell. The oscillation seems to happen
more
frequently whenever the modecleaner (MC) is brought on-line but has
been
observed in the PSL alone, when the servo gains are incorrectly
adjusted.
- The source of an ~80 kHz spike in the frequency servo mixer monitor
signal was found to be a cable leading from the 80 MHz VCO to the MC
servo
amp. Touching the cable would remove the spike.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
No report received.

-------------------------------------------------------------
4ITM03 measurements will be complete this week. It will then be
ready
for
cleaning and shipment LA. The interferometer was losing intensity
in
the
zoom mode yesterday. There are anecdotal fixes, but no verifiable
cause
has been found... yet.

From: Ruth Brambila
I have almost completed deleting the duplicate encumbrances on the list Florence gave me yesterday. Only two are left to be investigated and deleted out. I'm trying to get the information today to delete those today.
I am still working on updating LIGO's fiscal year change on poeta's. Am a little more than half way thru on the subcontracts. The updates on the blanket po's have just been begun. The priorities are those which currently have invoices outstanding. In making the transfer of funds, we ran into an "on-line receiving" problem in Oracle a few days ago which is still being ironed out. The wrinkle was that in order to cancel out a line with an old poeta, we had to receive on-line in the amount of which had already been billed and paid by Caltech. A defined course of action has not yet been established to circumvent this in the future.
I still have a spreadsheet from Ed/Cindy which requested for deleting current commitments. I hope to be working on that list next week. I would like to complete the FY2000 fiscal year update first.
I just began using a new form for change orders to subcontracts which are going to the contractors. This will take the place of the Oracle P.O. which is confusing and cumbersome to the vendors. Previously, the Oracle P.O. was being faxed or mailed to the vendor which was not easy for them to make sense of and which was too long for the amount of useful information it contained for them. Now the new form (created by Tom Currier jointly with Jose Tiana) will be utilized to notify the vendors of change orders. You'll be seeing it soon.

The contract with Yakama Industries for tumbleweed removal at Hanford
was extended for one year at a cost of $46,000.
Biplab Bhawal
o Completing changes in recycling summation code to accomodate
frequency-noise and intensity-noise in input light.
o Documentation of recycling cavity code finished. The changes
now being made in code will be included later.Hiro Yamamoto
* Had a meeting with Stan, Matt and Luca to discuss about the simulation
work for
the LIGO locking.
* Had a meeting with Biplab, Matt, Luca, Ed and Bruce about the future
of the simulation
work.
** Next version of alfi, alfi4, is expected to be available by
the end of January, as
a preliminary version.
** The simulation works will be grouped into two. Biplab and
Hiro will keep working
mainly on the development of the simulation engine and
application - user interface,
and Matt and Luca will work on building the actual LIGO
system based
on the e2e framework.
** Matt and Luca will build 6 mirror optics systems using e2e to
play with to get
familiar with the fields and signals in that system.
** In a couple of weeks, Hiro and Biplab will start working on
the implementation
of the new optics model which was formulated by Matt based
on the old works,
especially the modal model implemented mainly by Biplab.
I worked to assist Dave McClleland (ANU) in developing a
grant proposal to their funding agency for LIGO-related software
R&D. I asked Kent to participate in this.
[Kent Blackburn]Held the weekly dataConditioningAPI meeting
* (JKB) This week was spent in preparation for a new patch level
release of the alpha LDAS system. This will raise the version
of LDAS from 0.0.7 to 0.0.8 if all goes well during the
build today (Thursday). The primary changes associated with
moving to 0.0.8 are a new set of autoconfig and make files,
support for DB2 6.1 in the metadataAPI, enhancements to the
frameAPI to more completely support frame structures and the
ability to concatenate data from different frames into ilwd
data object, full functionality of the lightWeightAPI based
on the baseline requirements, and faster database insertions
and queries.* (JKB) Along a parallel path, Peter Shawhan as develop a userAPI for
accessing the database. The first implementation simply connects
directly with the DB2 server, but Peter is now working on the
minor changes to get his database browser to access the database
throught the LDAS managerAPI and the metadataAPI which will then
allow remote database browsing of any of LIGO databases (at the
sites or other LDAS installations). In addition, Peter has developed
this database browser using TCL/TK which will allow integration
of his work as a module in more advanced LDAS userAPIs of the
future which will also incorporate TCL/TK.* (JKB) LDAS has nearly finished implementing its problem tracking system
based on GNU's gnats software. It is a web based bug/problem
tracking
system with an extensive set of interfaces, including database
functionality which will allow for powerful electronic tracking of
bug/problems/changes to the LDAS software. NOTE: this system has
been configured with 4 separate databases to support LDAS, E2E, GDS
and CDS. Many thanks to Bruce Sears for setting this system up.* (JKB) Met with Rolf Bork of CDS to discuss the configuration process used
by LDAS and compare with that used in CDS. Much of the discusstion
focused on LDAS' use of CVS and the process model that surrounds it.
LDAS, at Rolf's request will establish a new CDS repository under
the
SPICA CVS server to allow CDS to begin to learn and utilize this
tool.
A follow-up meeting will take place later this week to implement the
directory tree design, accounts and administration priviledges for
the CDS group.* (JKB) Attended a kick off meeting for the 40m/TAMA data analysis
spearheaded by Walid, which marked the beginning of this project and
outlined the possibilities for work within the LDAS framework as
much
as possible for the analysis;
with PSU/UTB/ANU in which a strong effort is being made by LSC[Stuart Anderson]:
participants to develop algorithms for conditioning data under
the LDAS standards.* (MB) MPI:
- Had a meeting with Kent and Phil on command line arguments
format for wrapperAPI.
- Went through Grace's code.
- Installed mpich on propus, tested examples.[[Alex Ivanov]
* finished frame builder interface functions in FrameCPP and FrameAPI* wrote new frameAPI code to access serial data structures in a frame
* implemented four new configuration flags
[Mary Lei]
* (ML) Added timing and debug commands to metadataAPI
controlled by resource file variables.* (ML) Populated metaserver database with data from ilwd for
new tables.
[Peter Shawhan]
* (PSS) Continued work on graphical user interface to
LIGO database. Added parsing of simple LIGO_LW,
as a step toward making it use LDAS APIs to
communicate with the database.
Wallace ordered the hardware for building the racks at the Observatories for the
beouwolf cluster units.
Ordered the UPS for the 6th floor racks which has arrived and been installed by
the group on the 6th floor.
Installed second UPS for Caltech LDAS hardware and replaced bad
ethernet cables. Began working on random system crash of the LLO LDAS
dataserver. Worked with James Patton to bring the LIGO HPSS archive
into complaince with the new CACR user account structure.
[Bruce Sears]
* (BS) LDAS GNATS Bug Reporter:
- Discussion on categories and those responsible, and implementation.
- Creation of similar set-ups for CDS and GDS.* (BS) LDAS Web Home Page:
- Discussion with Ed.
- Implementation of a CGI to dynamically create appropriate links to
LDAS log files. (in works)
MIT:

Barbara installed the new iteration of the web application for LSC reporting
including new web forms and database changes for Participation. A new LSC
Reports page gives instructions for completing the web forms.
Created an application for Rita Torres to use to produce an LSC roster.
Application includes database, entry forms, and reports. Two reports are
used to dump the entries out as html pages -- one for a roster in alpha

Suresh had a meeting with John Dundas, ITS concerning monitoring of our Cisco

monitor various router parameters using a package called NetHealth. Once we are
familiar with this, we need to buy element licence for the permanent access.

possibilities of direct ATM routing between subnets without using routers. This
is in fact possible using a ATM service called MPOA (Multiprotocol Over ATM).Larry is going over maintenance contracts to get some minor issues worked out.

Worked on preparing the paper work for 13 new trips taken recently or upcoming (13 Payment Requests and 3 Advance Requests). There are approximately an additional 10 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 41 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 11 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.
I have not seen any significant change in the time lag for receiving checks. They still continue to hold checks in Disbursement Audit for up to an additional week after the check has been issued. This additional lag adds significantly to the lag that already occurs in Travel Audit/Accounting. I have started receiving T numbers. We'll have to see how long this lasts this time.
Performed normal recording and filing associated with Travel and Reimbursement.
Prepared the Travel/Vacation Itinerary for the Week of January 17, 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.
