The Project Control Meeting Agenda for Monday July 19, 1999 will be:
CANCELLED
LHO mode cleaner work continues
Water Well Problems: We just received a $12K bill for the well
rework
that occurred in May.
New staging Building: The contractor is 99% complete with the
building.
Only punch list items remain. The contractor submitted the shop drawings
for the bridge to the mezzanine.
Compressors: Apollo started legal action against C&K Compressor,
the
company who guaranteed the as-installed compressors to be oil free.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC6(Y-MID): In the last two weeks, the Roller System has been positioned,
after having the Bellows Platforms modified to make room for it.
The top
Dome was removed and the upper Work Platforms installed. Next
the 'D'
Nozzle conflat covers were removed and the Support Tubes were installed.
The south chamber door was removed and the Support Table/Downtube/Optics
Table Assembly was then bolted to the Support Tubes. With the
Support
Tubes now centered, the Bellows' were installed and the custom conflats
torqued. Next came the V-Blocks connecting the internal load
to the
external structure. This allows the Jib Cranes to be removed
and the
16.5" seal to be torqued.
We were unable to get one seal to work and a chamfer was found on the
gasket preventing the gasket from holding in place during conflat sealing.
This set us back one day as we replaced the Jib Crane, disconnected
and
removed the V-Blocks, removed the Bellows, replaced the gaskets, and
then
reversed the disassembly. The new gasket snapped easily in place
and on
we traveled.
Staging of parts and fixturing for Phase 2 was completed 7-14, and stack
building began in earnest 7-14 pm.
BSC5(X-MID): The Adapter Plates were aligned allowing the scissors
tables
to be installed (near future) followed by the Fine Translation stage
(yet
to be delivered.)
BSC4 : The three leaking gaskets on BSC4 have been replaced and it is
now
pumping down for leak tests (See Corey Gray or Dennis Coyne)
Computing:
----------
(C. Patton)
I just returned from vacation, so this week has been spent catching-up
on everything that went on while I was away. More Matlab and
toolbox
licenses have been purchased and installed. Completed installing
the
new color laser printer on the Unix systems. Backed-up the user
accounts, moved some user accounts around to keep disks from getting
too
full, got caught-up on accounting paperwork, and helped several PC
users
with several different problems.
Electrical & Electronics Systems:
---------------------------------
(R. McCarthy)
Installation of the UPS for the Control room is progressing. All
conduit
and cable have been installed and final terminations will take place
Friday. Hopefully we will have a Control room computer and ATM
switch on
the UPS early next week.
Conducted a walk through with US West (phone company) for an estimate
on
running phone and data lines to the new staging building. We
should have a
quote tomorrow.
Worked on isolating a source of 52k Hz noise on the small optics
suspensions. The are appear to be related to the coils.
Early next week I
will shut down the power to the controllers to ensure we are not
introducing the noise into the ckts.
Physics Environmental Monitoring
--------------------------------
(M. Lubinski)
I will be the person to look after PEM equipment
here in consultation with
Daniel Sigg and Matt Smith. I am trying to get
up to speed on all the PEM
equipment, location, operation, testing, calibration,
and some data
analysis. We are currently looking at
the data from seismometer in the
LVEA.
Detector Installation: Installed the Hytec BSC Control Rack. The system appears to be functioning properly after we worked out some software bugs. We exercised the systemextensively with U,V,W Translations, rolls, and yaws. Hytec is going to makeup some different length cables (of the lengths they brought, some were to long and some were to short), and send them our way next week, thus keeping our cable trays neat. We are continuing the cleaning and staging of equip.and parts for the buildup of BSC 1 which will commence next Monday 7-19-99. (Rich Riesen)
Optics: Cleaning (36) ISC viewports from MDC.
The glass to metal seal is filthy, and is taking 3 or 4 cycles through
the ultrasonic cleaner to stop the shedding. Also received the reworked
viewports from Varian this morning and will begin cleaning and assembling
these for Mike Smith. Optics for COS viewports received from Helena last
week. Ordered additional small LN2 dewars for the SEI installation and
labs. We're going through a lot of gas and since the big dewars for
the cryopumps are yet filled; we have to import from Baton Rouge.
We had to rob the lab source Tuesday so Hytech could
float air bearings. The machine shop is getting a lot of use, modifying
tooling for Rich and yesterday I had to machine two rollers for GNB. Placed
an order with a local contractor to provide a roof for the hazardous material
storage bunker. With the summer heat, we've had lab solvent drums
rupture so an elevated roof will permit shaded storage, out of the rain
as well. (Jonathan Kern)
Electrical installation: The small optic suspension test stand control rack has been wired and is ready for preliminary testing. Two 20 amp circuits for the Hytec control rack are installed. Permanent CDS rack power tie-ins have been made to racks 1X4 thru 1X9 and 1X22. (Rus Wooley)
EE lab: Redhat Linux 6.0 is received and is in the process of installation
onto the lab PC. Ordered and received few soldering accessories.
CDS: Stored new arrival equipment from Caltech and Updated hardware
inventory on the web. (Juilien Svoboda)
Bake Oven: We have installed a N2 leak for calibration purposes. We are continuing to bake BSC bellows. (Tom Evans)
GC Computers: We are beginning the installation of Solaris 7, and will eventually upgrade all the Sun GC machines to this version. (Tom Evans)
Other: Attended oracle training in preparation for the dark period. Worked with Larry to get PC requirements and have upgraded in preparation to run Oracle. Have reset up petty cash software to be able to process checks with new charge codes and reimbursement requirements; and began paying bills on site again as a result. Updated passport software on everyone's computer (except Mark's because he is out this week). Obtained and distributed new Caltech ID cards. (Bonnie Wascom)
Mark Coles obtained a "Morgan Coil" - harmonic coil used for precision
magnetic field measurements of accelerator magnets, as a loan from FNAL.
Jonathan and Mark measured the AC multipole magnetic moments inside BSC3
over the 4th of July weekend by wrapping the entire assembly in clean room
wrapping and suspending it from a PVC pipe between viewports in opposite
doors. We made measurements of the dipole, quad, sextupole, octopole, decapole,
14p, and 18p. We also made measurements in air at mid height in the LVEA
by suspending the coil from the crane and we made background measurements
by replacing the coil with a load resistor in the amplifier chain. This
data is now being analyzed to see what impact it might have on the LSC
and ASC dynamic range requirements. While the coil is constructed with
very tight dimensional tolerances so that it can accurately measure field
derivatives, the areaXnumber of turns is small, so it's important that
we dont fool ourselves.
----------------------------------------------------
DETECTOR GROUP -- Whitcomb/Shoemaker
(WBS 1.2, 1.3)
----------------------------------------------------
IAS Initial Alignment (K.Mason, M. MacInnis)
The componants for ISCT10 have been assembled and will be boxed for
shipment to Hanford. Assembly of ISCT9 componants has begun.
Recalculated optic positions and orientations for FMy and RM. Dennis
Coyne and I have finalized theodolite positions and orientations. Both
optics will be repositioned next week in Hanford using the PLX periscope
to view around installed optics.
IO Mode Cleaner Commissioning (N. Mavalvala)
Since the successes of the previous week when
we locked the mode cleaner
using P-polarized input light, we characterized
the control loops, which
were
as expected. We are in the process of modifying
the servo characteristics
to engage the bypass path (which was too conditionally
stable to use
without more careful characterisation) and to
use the length path.
We also measured the length of the cavity using
a resonant RF sideband
and found it to be 15.256 m (it needs to be 15.240
m, so we'll have to
move
MC2 during a vent).
Most recently we have locked the mode cleaner
using S-polarized light,
which is the design polarization. Some new mysteries
have emerged:
(i) We can detect no appreciable S-polarized light
in transmission
through SM1. We measure the polarization ratio
S/P of the input beam to be
around 1000, yet we see only P light transmitted
through SM1. We placed a
polarizer cube in the transmitted light beam
line to remove P light and
were
then able to pick up a miniscule amount of S-light.
Even with 100 mW of
input power we would expect ~150 uW of light
to arrive on IOT7. (Is it
possible that SM1 is a high reflector for S,
rather than the speced 0.5%
transmitter?)
(ii) The visibility we measure is only 30% (we
expect ~100%). Since we
have no measureable transmitted light and the
spot we see using a camera
pointed at MC2 is too speckled to tell, it's
possible we are locked in the
wrong mode, but not very likely, since we are
well aligned (checked using
P pol). We are
about to set up a ringdown measurement to measure
the finesse of the
cavity.
(iii) We tried operating at higher power to get
some transmitted light
through SM1, but that drives MC3 into large pitching
motion, completely
correlated with light build up in the cavity.
Next will attempt to
* lock the cavity with modified bypass and length
control paths
* realign the input beam path to center spot
on MC1,3

Prestabilized Laser -- Peter King
--------------------------------------------
- In an exercise aimed at exploring if the beam quality of the laser
could
be improved, laser SN #107 was re-aligned. Upon return from Lightwave
Electronics, the performance data reported an M-squared values of 1.16
and
1.17 in the horizontal and vertical directions respectively.
After re-alignment at Caltech, M-squared was approximately
1.10 in
both directions with a small, ~100 mW, drop in the output power of
the
laser. The phase-correcting EOM was then installed between the
NPRO master
oscillator and the power amplifier. After a minor re-adjustment
to the
alignment of the laser, the M-squared parameter was re-measured.
It was
found that the EOM did not affect the M-squared parameter. A
result that
is consistent with previous experience with the laser.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
We worked on the design change on the PSL/IOO table associated with
the RFAM measurement and the use of Brewster-angle polarizers. The
new
layout uses a pair of Brewster polarizers before and after the three
EOM chain, and three steering mirrors after the EOM having an angle
of
incidence ~22 deg for two of them and a near-normal incidence for the
other
mirror. This mirror has about 1% transmision to give a
polarization-insensitive signal for RFAM measurements. We will order
these
optics soon.
We have also worked on new beam alignment fixtures for MCMs
Dan Dickrell and Sany Yoshida will travel to LHO next week.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
We have the temperature stabilized in Lauritsen
to the point where we can
take data on SPETM04. Unfortunately this
thermally stable time is not
coincident with a vibrationally stable time.
Therefore we are accepting
data with a vibrational signature, namely a bullseye
pattern with 3 sigma
P-V amplitude of ~1.2 nm. The optic is
to be handed off for scanner
measurements on the 16th and is to ship to Hanford
on the 23rd.
CSIRO performed measurements on 2 of the 4 Beamsplitters which needed
re-work last September. The first type of measurement was of
the surface
figure (looking for change in curvature pre to post coating) using
the same
technique as is used for final acceptance of the polished optics.
The
second type was measurement of coating thickness, using elipsometry.
Bob Oreb of CSIRO is presenting the BS coating measurement result at
a LIGO
session which is being held July 21 at the Denver SPIE meeting.
The LIGO
number for this paper is: C990866-00-D
The following is an e-mail excerpt comparing results of our post-coating
surface figure measurement of BS01 to the predicted surface figure
of BS01.
The prediction is based on pre-coating measurements plus the coating
induced changes of other BSs measured at CSIRO.
>From Bob Oreb:
_________________
Thank you very much for the feedback on our BS01 coatings paper.
I would like to make a couple of comments regarding your and our results:
1. You estimate the ROC of Side 1 to be between -66 km and -188 km with
a
preferred value of -140 km. From our measurements on the uncoated
and re
polished BS01, side 1 had a sag of ~ -10 nm. If we assume that the
coatings deposited on the re polished BS01 behaved or influenced
the
substrate in the same way as our assessment of the earlier coatings
then we
would expect the curvature of side 1 to change by ~ -45nm from its
uncoated
state. This would then make the final coated surface 1 curvature have
a sag
of ~ -10 - 45 = - 55 nm or ~-91km. This value lies comfortably within
your
estimated spread of values quoted above.
2. Your measurements indicate that side 2 appears to be 50 nm more concave
as a result of the coatings. Our measurements indicate that side 2
became
45 nm more concave (and side 1 45 nm more convex). These results are
very
close.
3. "HR coating is known to be compressive" - this is consistent with
our
measurements which show side 1 becoming more convex and side 2 more
concave
as a result of the HR coating. Our results also indicate that the AR
coating has the opposite deformation effect than the HR coating and
so it
may have tensile stress. It would be useful to get an explanation for
this
apparent difference.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
This week I attended several talks at the Amaldi Conference, worked
on the
up-date of the Vacuum Document, reviewed the LOS installations procedure
to
be able to help install the BS next week at Hanford and cleaned some
optical stages.
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE
The 2K APS PO telescope is being aligned at CIT, but alignment will
not be
completed until the week of 7/26 when Mike S. returns from LHO. After
alignment, it will be disassembled and shipped to LHO by 7/30. A production
contract for 12 PO telescopes is expected to be let the week of 7/26.

alignment apertures for the PO mirrors have been fabricated and tested
with
the 640nm battery-operated diode laser pointer. They will be air baked
and
shipped to LHO on 7/16. Ken M. and Mike S. are adjusting the placement
of
the final design PO telescopes on HAM9 and HAM10 optical tables to
insure
that there will be no interference of the PO beam optical train hardware
on
the table.
STEERING MIRRORS
10 sets of 2 inch steering mirrors are being baked at CIT and are expected
to be hand carried to LHO on 7/18. Steve B. will assemble the mirror

[Stuart Anderson]
Installed and started 2
week test of 200GB network attached
hardware RAID disk cache from Network Appliance. This installation
utilized the last of the 4 LIGO fibre pairs running to the 6th floor
of Millikan, and also involves upgrading Linux to support NFSv3.
Meet with StorageTek to discuss
their current and future offerings
for mass storage as a possible solution for the on-site and main CIT
LIGO data archives.
Started XML database of software installation rules.
- - Reviewed the plan for web services with Gary and received an ok to proceed.
- - Resolved problems converting several long LSC reports to PDF.
Access had
problems paginating the memo fields in the report. Then the pagination
didn't hold when the report was transferred to Word (the "Publish
with
Word" feature isn't quite what it seems). Cleaned up one report
that had
unprintable characters sprinkled throughout. Helped connect Irena to
the
server with the LSC reports database.
- - Continued to help with Amaldi items -- applications, abstract
registrations, web site changes, submission of papers, etc.
[Christine Patton]
Subject: LHO weekly report

Started working on arrangements for our LIGO/SURF Students' visit to LIGO/Hanford. There will be 12 students, plus Ken Libbrecht, traveling this summer. They will be departing on August 12th and returning on August 13th. A number of the students have requested a layover on the return in Seattle for the weekend of August 14th and 15.
Completed 27 Expense Reports, some of which were extensive, involving 2 or more pages each. Many of these reports were still not taped or completed by the Traveler, and required additional time for completion. Also worked on a number of problem issues which required a good portion of my time. Received, but not yet completed my audit, 25 Expense Reports. These should be completed in the next couple of days, barring unexpected delays.
