LIGO Hanford Observatory (LHO) Operations

Facilities:
-----------
(Otto Matherny)

George Grant Construction Co. physically started working on the Staging
Building. Rough grading and foundation compaction was accomplished.

Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)

Installed 6 BSC Piers in LVEA and aligned Adapter Plates at HAM3.

Staged Optical Lever items.

After delaying us a week, our shipment finally arrived from Allied.
Work on HAM8 began on 11/11 and is going smoothly. HAM8 should be
sealed up by Thursday and a leak test of HAM8 & 9 will occur later this
week.

Began positioning BSC piers at x-end.

BSC SEI 1ST ARTICLE:
Everything is ready in the garage at HYTEC (Los Alamos). We will be
lifting the Optics Table/Downtube today to install the isolation
system Springs.  After that Dynamic Testing.

To get to this point, over the last week the Bellows have been
installed along with protection for them. Alignment pins were designed
and built, and used for aligning the Leg Elements and Optics
Table/Downtube. The PZTs which drive the Fine Actuation system are
still at the vendor where they are installing notch filters in the
controllers and checking the stacks for any damage. The Airbearings
have been performing well with no sign of stiction in a few days. The
Actuation software is coming up to snuff with no bugs seem for a few
days also.
 

Computing Systems:
------------------
(C. Patton)

This week, with help from Tom Evans (MIT), I have created a /home/dcc
account on our server and setup an automated job on sirius which will
maintain an up-to-date copy of the /home/dcc account from sirius on our
server.

Framemaker 5.5 is installed and running on our server. We have 5
licenses.  We also still have the two licenses for version 5.1. Still
waiting to receive the other software that has been ordered. Once the
last of this ordered software arrives, hopefully next week, we will be
completely legal and up-to-date with the most commonly used software.
From here on, software orders should be for special purpose software
and for upgrades.

Preparations are underway for transfer to the permanent T1 line IP
addresses. Also, started the procurement process for the modem pool
equipment.
 

Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)

The last of the equipment mounted on Y2 has been removed. The tube is
now being monitored by gauge pairs (cold cathode and Pirani) mounted at
ports Y2-1 and 2-9. This data is being logged by the CDS system.

We are continuing the setup for the bake out of Y1. Sun River is
completing the setup of the blankets on the tube and 44" gate valves
and we are working on the blanket setup at the ports. The Turbos and
cryopumps are mounted at ports Y1-1 and 1-9 and have been tested. We
have added helium to top off the charge on 3 of the cryopumps per the
tech manual. The RGA has been mounted at port Y1-5 along with the
calibration cart and an auxiliary turbo cart.

We have had some problems come up this week. We have one of our boxes
in the process control system not working. This box controls one of the
DC power supplies and monitors the DC voltage and current, temperatures
and cooling water system. We are working on resolving this problem. We
have found a leak on PS1 cooling system on the threaded fittings going
to the power supply (not internal to it) and Sun River is fixing this.

LIGO Livingston Observatory (LLO) Operations

Vacuum Equipment (Allen Sibley)  The bakeout of the left arm manifold in the LVEA is complete. The data presented satisfy the secondary criteria that the sum of the partial pressures excluding water and hydrogen are less than 3.e-9 torr. Note that there are no ion pumps on this volume as there are in Hanford. They have installed bakeout blankets on the vertex area in preparation for bakeout commencing 11/13. Pumps have been installed on the right beam tube manifold and it is presently being pumped. GNB is on site and is inspecting and repairing the remaining gate valves. The right arm mid station valve has been rebuilt and staged back to corner station pending the arrival of O-ring material.

We are obtaining contract help to conduct the 50 cycle tests of the gate valves, planned to start 11/12.

Electrical Engineering (Juilien Svoboda) A PO was obtained for the network cable tester from Microtest, a PentaScanner 350. She is also getting ready for the re-work of the communication room which is planned for this weekend.  We are continuing to order support equipment, parts, and cabinets for the EE lab. Juilien also set up the CDS vacuum control system at the X arm manifold in the LVEA for PSI to use. Two racks were also set up at the Y arm end station in preparation for the fiber optic cable installation.

Slade Maurer has been labelling PCs, updating software programs and fixing some of the problems people have on their PCs. This job is still in progress.

Optics (Jonathan Kern) Jonathan spent last Sat, Sun & Monday at LHO with Peter King & Doug Cook in order to coordinate Livingston support of the PSL installation. We let the PO for the DI water system to Culligan. Parts for the cable trays and laser curtain in the optics lab are being delivered. We have received a partial shipment. Installation will begin as soon as all the parts are here. Jonathan is investigating various possibilities for vendeors for the PSL safety enclosure.

Facilities (Gerry Stapfer) We formally notified Hensel Phelps as to several deficiencies in the building. We have transmitted the electrical QA report to Hensel Phelps.

We met with Gulf Enginnering to discuss the erosion/landscaping status fof the site. GEC has provided us with preliminary concepts. The plan is to get a preliminary design by the end of the year which we hope to show to Barry on his next visit here in January.

We have accepted the Y1 beam tube module. We are preparing to vent it for the gate valve refurbishment at the corner station.

Preparation for Bakeout (Cecil Franklin, Kerry Stiff) We have gotten a schedule for the completion of X-arm B/T Enclosure Cleaning to be complete by 11/29. This week we cleaned 3/8 of  the X-1 module beam tube enclosure with water and high pressure sprayers. We explored the beam tube grounding issue and attempted to survey the quality of ground rods left behind be CBI. We Discussed this problem with Rai and developed a new plan of attack.

Detector Installation Preparation Anthony Rizzi  was at Hanford last week working with Jay Heefner to start learning about the LSC system works and how it will be installed. We are also pursuing the installation of a weather station in collaboration with the Geographic Information Systems Dept. at LSU.

Site Administration and Infrastructure Bonnie Wascomb got the satellite PO system up and running well.

Educational Outreach We made half size copies of the tutorial posters of the LIGO tutorial posters in the multipurpose room which have been foam mounted and that will be on display at the APS Plasma Science Symposium in New Orleans 11/19-20.

WBS 1.2, 1.3    Detector Group

40 m Interferometer (Nergis Mavalvala)
---------------------------------------

We locked the non-recycled Michelson with F-P arms. In this
configuration we were able to explore some interesting lock
acquisition phenomena involving the relative gains of the
common-mode and differential-mode servos.

Since then we are locking the full recycled configuration.
Again the interferometer locks only when one or more degrees
of freedom is significantly misaligned. Attempts to align
it after lock is acquired throw it out of lock. We are
chasing down possible saturation in the servo electronics.
The arm cavity differential-mode front end is a prime
suspect and several measurements have been made to ascertain
this. This loop also has little gain margin.

ISC initial alignment (MEZ for Mason, McInnes)
-----------------------------------------------
Completed testing of IAS equipment and new jigs and fixtures.
Traveling to LHO for alignment demonstration exercise at X end,
through end of next week.

ISC fabrication (Fritschel)
-------------------------------------
o Finished setting up the optics on IOT7 for the mode cleaner
transmission beam. As for the the mode cleaner reflected beam,
we received the electro-optic modulators and polarizers for
the fast safety shutter, so now we have all the components and
have begun setting up the optical train.

o Rana & I tested the analog modulation capabilities of our 100mW
CrystaLaser Nd:YAG laser, as a candidate for the photon calibrator
source. The results look good: using a separate Newport laser diode
driver, the 1064 nm output can be amplitude modulated essentially
100%, with response up to several kHz, with very little distortion.

ISC fabrication (Mavalvala)
-------------------------------------
Included electronic gains and basis transformation associated
with actuating the input beam via steering mirrors (rather than
the cavity mirror angles) in the IO mode cleaner wavefront sensing
controls. Documented and passed on to CDS.

ISC supervisory control code development (Daw)
----------------------------------------------
This week I finished installing Tornado, the board
support package for the Baja 4700 processors, and
the new boot PROMS. I advertised for undergraduates
to work on real time control software in VxWorks and
got 10 applicants in 24 hours (!) - one of whom has used
VxWorks before.

On the GDS side, my power spectrum software now heterodynes
the time series so that power spectra can start at arbitrary
frequencies.

ISC lock acquisition implementation (Ware)
--------------------------------------------
Nothing to report, spent the week preparing for the science
seminar.

--------------------------------------------

Prestabilized Laser -- Peter King
--------------------------------------------

- The PSL has been locked to the reference cavity, without the frequency
shifter, under the EPICS interface.  Unfortunately the 21.5 MHz frequency
reference card stopped functioning in the afternoon.  Probing portions of
the card failed to reveal any obvious reasons why the card malfunctioned.
The card is being returned to Caltech for repair.  The backup plan of using
two phase-locked function generators is undergoing implementation.

- Electrical power to the 2k IFO optical table enclosure is now drawn from
facilities power.  Inside the 2k laser area enclosure, cable trays and
facilities power have been connected.

- The PSL is now being chilled with the water chiller located off the LVEA
technical slab.  Its performance is being monitored and will be compared to
that achieved with the water chiller located 6' from the IOO/PSL optical
table.

- The schematics for the various PSL servo cards have been registered with
the DCC.

------------------------------------------------

Installation -

Qi-Ze and Sany worked at the Hanford site. Started to align the optical
components on the PSL/IOO table. Since the PSL beam is not available yet,
we are arranging a 700 mW NPRO Nd:YAG laser on the PSL/IOO table in such a
way that the beam travels along the same optical path as the PSL beam. We
are also planning to measure the RFAM of the electo-optical modulator by
the same NPRO laser arrangement. In order to use this NPRO laser on the
PSL table, they documented the operation procedure and now are waiting for
the approval.

Set up a He/Ne laser on the PSL table for wavefront measurement by a
Shack-Hartmann wavefront detector. Finished with the inital alignment
of the He/Ne laser for the wavefront measurement. The frame grabber was
found to be not cooperative with the computer available here. We are still
working on this problem.

We cleaned and balanced two 3 inch optics, and now working on the third
optic. Four magnets/standoff combinations have been glued on the rear
surface of the third optic.

Mode Matching Measurement -

Now back from Hanford, Qi-Ze is working on the alignment procedure
described last week.

Mechanical Design -

All of the IOO drawings have been brought up to date in the DCC.  In
The PSL-HAM Beam Tube design is almost ready for machining.

MMT3 Radius of Curvature Measurement

10" optics holders for the MMT3 are being machined.

Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------

The Radius of curvature has been measured on one of our Pathfinder pieces,
COC-A001, polished by HDOS.  The result is within less than 2% of the
measurement results obtained by HDOS, and CSIRO in their measurement
of this part. A 3rd independent measurement, done by NIST, gave an ROC
~4% lower than the other 2 metrologists.

There are still concerns about our ability to measure the mid-spatial
frequency characteristics of the core optics.  This will improve with our
continued characterization of the reference flat C.

We are carrying a delivery date of mid-December for a recycling mirror
and input test mass.
 

Core Optics Coatings -- Helena Armandula
--------------------------------------------------

REO Contract - COC's Coatings: REO is proceeding with the installation of a
filtered DI water system to be ready by December 7th.
Indium bonding status
Several tests were performed to evaluate the feasibility of using indium
bonding to attach magnet/dumbbell assemblies to COC's. Here are some
findings: The best indium bonds between glass and aluminum do not resist the
"swing test at 90 degrees".
Magnets rust after 3-4 weeks as consequence of exposure to HCl acid which is
used to clean the magnet's bonding end.
After applying an aluminum coat to the end of the magnets, adhesion of
indium to the magnet still remains a problem. (Coating the ends of the
magnets with copper could be a better option).
I feel that this bonding technique could be perfected and made to work but
not in time to be used with confidence in the first LIGO Interferometer.
Research has to be done on adequate fixtures, pressures, pressure holding
time, cleaning processes, even some other indium alloys.
 

Core Optics Support -- Michael Smith
------------------------------------

BEAM-DUMPS
The shop is still working on the fabrication of the cavity beam-dump. Ara is
finalizing the layout for the SEI-mounted beam dump for GB
RMHR3 in HAM3 and the LOS-mounted beam dump for GB 2K BSHR3P. Craig C. is
working on the triple hinge joint for the beam dump mount.

ARM CAVITY BAFFLES
Angel has determined the available views of the reflected IFO beams from the
arm cavity baffles during initial arm cavity alignment, which scatter from the
walls of the manifold tube at the mid station and are viewed by ASC. He is
completing the layout and mounting of the arm cavity baffle-right, which must
be mounted in the BSC chamber. Paul K. is in process of making detail shop
drawings for the various arm
cavity baffles.

ETM and PO TELESCOPE
CC Development will present a design review on 11/12/98 of the completed
working drawings for the ETM and PO telescopes. The finite element analyses of
the mechanical vibration modes of the structures are in process by an outside
vendor.

MOCK-UP
Ara has mounted a cavity beam dump into the BSC chamber.

PO MIRROR
Ken M. is in the process of sending out shop drawings to build a prototype PO
mirror.

CONICAL BAFFLE
Craig has completed the design of the cryopump baffle for the vertex station
and is making detail shop drawings. He is also working on the
triple hinge bracket for mounting the beam dumps to the walls of the BSC
chambers.

Seismic Design (Mike Fine)
--------------------------------------
1. Air Bearings:
The air bearings were tested under full load on Tuesday. There appeared to be
some very minor signs of stiction in two of the bearings.  Specialty
Components felt that there was a small particle trapped between two of the
bearing surfaces, and because the stiction was so small that Hytec could move
the system without worry of damaging the bearings surfaces. The air bearing
has been successfully tested in translation to the maximum range. Rotations
have been performed on the air bearings, however software changes are
required
to demonstrate full range combined motions.  Hytec would like to perform
several
more functional tests prior to qualifying the air bearings. It is necessary
to
rotate the air bearings about each axis and demonstrate combined motion
capabilities.  This is currently being performed at Hytec.

2. BSC Structural Hardware:
The actuation tests revealed that the support tube manufactured by Allied was
not to print.  It would appear that the machined OD cut on the outside ends of
the tube was not of proper length to adequately clear the vacuum tank.  This
problem has been communicated to Allied and the hardware will be reworked to
spec when returned from Hytec.
3. Near-Term SEI Hardware Delivery Schedule:
1 HAM optical table and 4 SUS alignment rails               11/12/98
1 HAM sets of springs                                       11/13/98

1. LOS Welded Structure:
Brookfield sent the first two structures and they still had gross
deficiencies.
Janeen reviewed the out-of-spec dimensions and felt that we can live with
them.
The structures are going out tomorrow morning at 9am for delivery early
Monday
morning. Brookfield will be late on shipping the height adapters. They were
due to be shipped today but will be shipped Monday after the inspection report
is reviewed.

Global Diagnostics System (Daniel Sigg)
--------------------------------------

Sigg at MIT for ISC-GDS general diagnostic work.

Physics Environment Monitor (Alex Marin)
-------------------------------------------
Matt is in Hanford and for PEM he is working for the new estimates of the
cable length needed for accelerometers and microphones.
We are in the process to design the muon detector (Alex and Ray Frey).

Optical Contamination (Daqun Li)
--------------------------------

The viton pancakes and seals which have been previously qualified
in cavity two were reloaded into cavity one for requalification
because of the higher post-viton losses observed in cavity two which
may be still associated with viton.  However, a more careful way of
requalifying viton, I think, is to try a brand new set of freshly baked
viton.  S. Bell and J. Camp have loaded a faraday isolator into the side
chamber of cavity three which is now under vacuum pumping.  Cavity
realignments and loss measurements for these two cavities will soon start.
In the meantime, ringdown and mode spacing data taking is still going for
cavity two, unloaded currently under requalification process.

The reflectivity of LIGO beam splitter witness sample is measured to be
49.0% +/- 0.6% at 45 degrees +/- 0.5 degree for p-polarization at 1064 nm.

WBS 1.4.3    Systems Engineering / Data Analysis and Computing

From TAMA:

Hiro installed LIGO's FFT program on a TAMA's
SPARC Machine, and explained
how to customize and simulate the TAMA
configuration.
Hiro gave a talk about the status of LIGO at
National Astronomical
Observatory, Mitaka.

GHS note - The wraparound in the report below makes this very difficult to read. This is an artifact of an obsolete mail software tool. I am unable to reformat this material.
 

End-to-end simulation engine:

Implementation of higher order mode generation due
to mismatch in radius
of curvature in mirrors is also finished.
Some time was spent in trying to make various
modules of the multimode
implementation more efficient. At present
multimode calculations for a
LIGO cavity upto order m+n=3 using Adlib primitive
modules take about 420
sec (in ultra 2) for 10 sec of real time. The same
simulation using Adlib's
faster "cav_sum" module takes about 40 sec if you
choose to jump 20
round-trip-time in each step or about 25 sec if
you choose to jump 40
round-trip-time in each step...Increase in jump
leads to inaccuracy in
longitudinal dynamic calculations (tolerable or
not ...it depends on
mirror speed and finesse) but insignificant error
in multimode calculations
if mirror-speed is zero or low.

Data Analysis Activities:

LDAS Software Developments:
(Blackburn/Farnham/Ehrens/Majid/Williams/Sears/Lazzarini):

- Developed near-term milestone scheduels for
initial LDAS deliveries to LHO by IO availability
detector milestone.
 
- Received [from Bork] and reviewed DRR action
items in preparation of PDR.
 
- Established specifics of hardware components to
  be installed at the sites and in Millikan
prototype for data distrbiution server.
 
- Worked to accelerate completion of genericAPI
  components and documentation. Work was
completed.
 
- held a number of internal meetings to finalize
definition of the FrameAPI's requirements and
specifications,
  as well as the parallel set of documents for the
lightweightAPI docs.
 
- Work proceeded in bringing up the Altacluster
(Beowulf) machine. We have enlisted the assistance
of CACR's beowulf expert (Jan Lindheim) in doing
this work to allow our people to continue software
development.

- Developed the ManagerAPI requirements.

- Rebuilt the Alpha Linux kernel and xntp packages
for Stuart Anderson.

- Code validation: continued writing test cases
for the underlying objects in the
   Generic API (LdasBinary class, LdasElement
class).  For now, all that
   remains to do for the C++ portion of the
Generic API is to complete
   writing test code.

- Investigated auto-documentation systems for Tcl.
  Rejected all of the existing auto-docs for Tcl;
Bbegan to design an output format for Tcl
auto-doc,
  to be followed by a perl script to make the task
  less onerous, at a later date.

General Computing

Livingston:

Modem pool was installed by consultants. LLO nends
to get more
information on its configuration ASAP.

Hanford:

We now have a copy of the DCC database on our
server.  We also have
an automated job that runs nightly on sirius to
update our copy of the
database from sirius.  Thanks to Tom Evans for
helping me get that
working.

Cullen Tollbom from PNNL is finishing up his part
of the connection to the ESnet for
the LIGO T1 line. He will also reconfigure the
CISCO router for the new IP
addresses.

CIT:

Multiple PC fixes have been performed this past
week. Mostly, corrupted
files/drivers that have caused some problems. We
have been using Norton
Utilities and have found the initial check for
problems to be useful. Every
machine so far has had items repaired (anywhere
from 7 to 270 fixes per unit).
It was found that using Nortons disk optimizer and
some of the other utilities
caused problems. Removal of the Norton Utilities
from the system in most cases
also removed the problems. So as a standard
procedure we are running the check
only and then removing the package, the other
utilities we will not be using
until we can test them further.

Cadence is still not loaded correctly. The license
files being sent and
software pkgs. are not matching up. Unfortunately,
we can't discover the problem
until the installation has started or is
completed. Hopefully, we will receive
the correct pkgs. to match the licensing this
week.

The Ricoh scanner is closer to being fixed. We
were able to eliminate any
hardware issues and have narrowed it down to a
plugin and driver that is being
used by the scanning application package. Barbara
is now working that issue.

Resolved multiple procurement issues with SUN. We
discovered the procurements
over the past few months did not get where they
needed to. Two of the
procurements (the mail/www server replacements)
were sent to SUN but did not get
to the right people. Another procurement fell
through the cracks during the
transition from Michael Butler leaving the project
and one other procurement is
still being checked out. Phylis is now working the
issue.

Still working on software installations for the
new server. Most of the
shareware pkgs. have been installed and are
currently working on license
transfers for the other pkgs.

Barbara K. has been automating items for the DCC
as well as updating web
pages.

Working on getting multiple quotes for LDAS
hardware and working on the
logistics for the network setup.

Bill Tyler and Ed Chargois have been working on
resolving some of the issues
we have with some of the cabinets being used for
the GC servers. The replacement
hardware for the cabinets should arrive next week.

Multiple account fixes mainly password
replacement. Just as a reminder
people should change their passwords every 3-4
months. We also have a list of
people we will be contacting that absolutely need
to change their password. [AL NOTE: Thanks to
Stuart Anderson we have a password-busting daemon
that runs in the background, all the time. It is
unbelievable the kind of passwords some of our
people choose! I asked Larry to lock these
accounts out first, then inform their owners, but
he is too kind.]

Installed another FORE 3810 unit on the 6th floor
of Millikan. It has been
programmed but still needs to be tested out.

 My computer was down for a couple of days.

 For I. Petrac did edits to change order No. 3 to Allied Engineering, change order No. 7 to Brookfield Machine, change order No. 3 to Pegasus Manufacturing, change order No. 5 to Senior Flexonics.

 With S. Meshkov and Sponsored Research, verified that all pertinent information was provided for the Amaldi Conference. Sponsored Research reviewed the data we input to FastLane.

 For P. Lindquist distributed the Draft end of September progress report.

Irene Baldon

Please note that I was gone all of last week (11/2 through 11/6) and that this report covers one and one-half weeks in October and one-half week (this week) in November.

Arranged and processed the paper work for 22 new trips to various locations, with an additional 23 trips arranged but the paperwork is still being processed. Additionally, changed or canceled 9 trips to various locations.

Worked on the ever present backlog of Expense Reports and completed 37 reports.

I talked to Dlorah Gonzalez, the head of mail services. Near as I can tell, there will be new mail codes made up for the sites. They will be 18-34 HAN and 18-34 LIV. Obviously, this means that mail to the sites will still come here first, but these new mail codes may help in sorting mail. We’ll see.

Dealt with various and sundry office and phone moves. We’ve got a visiting graduate student hanging out on the sixth floor of Millikan: Koji Arai, who has connections with Seiji Kawamura.

Continued the elusive pursuit of getting the site paychecks sent directly to the sites. This involves setting up an entirely separate paycheck distribution code, one for each site. Those who wanted their paychecks sent directly to their homes should be receiving them already. Those who wanted their paychecks sent to the office will need to wait a while longer.

PLEASE NOTE: If you are expecting visitors coming here to Caltech in the next few months and haven’t let Donna or me know, please let us know so I can plan for space accordingly.
