The Project Control Meeting Agenda for Monday November 15, 1999 will be:
CANCELLED
Special Items:
Fringes in the 2K LHO Michelson!
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #64, consisting of
ETM Telescope Assemblies 002, 003, 004 and 005 was
released earlier this week.
Load #65, consisting of two reference cavities, is
vacuum baking at this time and is scheduled to be released
Friday, 11-12-99.
A component of the automatic shutdown and autodailer
system in the control panel for Oven A was found to be defective
this week. The manual settings of the output variacs are being
used as the sole redundant over temperature protection (temperature
controller is primary protection) until this component can be
repaired.
Vacuum Bake Oven B is being repaired (welded) again
and should be available for re testing next week.
Core Optics Support:
--------------------
(D. Cook, B. Weaver)
Through a big effort of several
people we managed to complete the
alignment of the 2K Core Optics in the LVEA,
coupling them with the APS
telescope and its steering mirrors, the IOO optics
and the Mode Cleaner.
The PSL beam was propagated through the APS telescope
and its steering
optics and onto a target at the HAM 10
view port where it will eventually
enter the IOT10 optic table. With the beam now
propagating through all the
optics, fringe patterns were observed in the
Mode Cleaner!
It was necessary to reset most of the Optical Levers as part of the
final
alignment. For your information if you monitor optic levers remotely,
here
are the
changes:
ITMy-2k nulled ( a loose mounting base plate
was suspect in large changes
during pump
down).
ITMx-2k nulled (after it was reinstalled following
x-arm spool replacement)
FMy -2k & FMx-2k, MMT3 nulled ( after the core
optic alignment changes)
RM nulled (after laser diode replacement)
BS-2k (no change)
ETMy-2k (remote monitoring capability only)
The optics tables were checked for final level
(no changes were made),
optics were check for proper safety stop settings,
the core optics went
through a final CO2 cleaning where necessary,
the RM was purposely
misaligned for the 2k "short-arm" test, temporary
fixtures removed, SUS
controllers checked out, bodies were removed
from chambers and the doors
were replaced and the pumped down began.
The last of the 2K (ETMx) Core Optics will be
readied today and installed
next week if all goes well. We should be staged
at the X-MID by Friday.
COS
Betsy Weaver
Last week, we finally, successfully aligned the mid-station COC's.
As I'm sure you've heard, we were able to see
fringes from the
APS telescope output in HAM 10.
Mike and I aligned the optical
train late last week to point the beam at a target which represented
the view port. Haisheng and Peter revisited this alignment earlier
this week and fine tuned it. The beam exits the window correctly.
Although one would think that with last weeks major accomplishment
behind us, things would calm down, however Doug and I have found
ourselves busier this week. We are currently resuspending the
ETMx
mirror after it's vacuum bake - it is due for installation at the X-Mid
next week (the tilt angle came back to almost 0 degrees - off by
maybe a minute). I am also trying to assemble the ETMx Telescope
that just came out of the vacuum bake on Tuesday - also due for
installation next week. I just received the ETMx beam dump which
will begin it's processing (cleaning and baking) today - ALSO due
for installation next week. We are cutting it close.
Monday, John Worden helped me install the conical baffle in the
X-manifold in the LVEA, taking advantage of the easy access with the
spool piece sitting on the floor. This baffle went in a lot easier
than the
one at the Y-Mid. It still took some fussing, but we managed
to get it
rigid and unmoving.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
4k HAM Installation work:
Air Bearings are installed on HAMs 1,2 &4 (HAM 3 is receiving air
bearings
as I type).
The Crossbeams were installed and connected to the Support Tubes on
HAMs 2&3;
other than final leveling, all 4k HAMs are ready for stack
installation--which is dependent
on processed Seat availability.
2k BSC Installation work:
Stack was installed and the chamber was sealed up at x-mid last Thurs.
afternoon.
Seat exposure time was ~29 hours w/ a humidity ranging from 15-29%.
This
concludes
SEI Installation for the 2k interferometer at LHO!
4k BSC Installation work:
Staging began for work on BSC3.
Computing:
----------
(C. Patton)
Continued network security maintenance. Continued moving computers
around to upgrade some computers and move the older computers out to
the
Mid and End stations. Continued trying to contact the Sun
representative to get maintenance contracts renewed.
Did the usual backups, helped with several printer and PC problems and
kept the GC accounting paper work up to date.
Electrical & Electronics Systems:
---------------------------------
(R. McCarthy)
Installed the necessary electronic components for the ETM-X install
next week.
The controller will be tested tomorrow. The database was built
today and
all the
signals are present. The cabling for the auxiliary equipment
is being
completed
today and should be ready for Monday. One minor problem is the
lack of a
Xycom 220 board. This will cause some minor inconveniences but
work arounds
are being installed.
We have decided to introduce some more competition on site with the
electrical
contractors. This week I met with American Electric to bid some
jobs for us.
They are a reputable company and I expect some very competitive bids
between them
and Sun River. Not that we are unhappy with Sun River it is just
that
sometime
contractors get complacent.
BSC#2: Completed stack buildup, completed cable installation, did continuity
check, all OK. Spring seat/shim exposure time 31 hrs. 45 min. Corner
station
now being pumped down. (Riesen & co.)
With the help of Janeen and Helena, Gary and Sany continued preparing
small
optics
suspensions. As of Nov. 10,
One Mode cleaner flat mirror has been balanced.
All six magnets, a wire standoff and a wire guide rod have been glued
to
the other mode cleaner flat mirror, two mode matching telescope mirrors
and
a steering mirror.
A wire stand off and a guide rod have been glued to the mode cleaner
curved
mirror.
Bake out of X-1 has begun.
Most of the week was preoccupied with preparation and execution of the
LIGO
Science Symposium and Inauguration activities. A fuller weekly report
will
be issued next week when things get back to normal.

Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
Report from LHO (Peter, Haisheng, Nergis):
------------------------------------------
This past week was spent rather tediously aligning
the IO beam to the core
optics, but with the big payoff of seeing for
the first time interference
fringes in the core optics!
Alignment of the mode matching telescope got off to a bad start last
Friday when it was discovered that a side magnet on MMT1 had fallen
off (the one the osem was using, of course). When we tried to move
(in
place) the osem to the other side of the suspension, we saw that this
magnet was too low and would interfere with the osem. So we pulled
MMT1 out of WHAM7 and rehung it with a new wire, raising it up a couple
of
mm; in the process we also adjusted the centering of the face osems,
two of
which had also been significantly off-center. We then went through
a
couple of iterations of co-aligning the IO beam with a reticle pattern
that was being projected through the Y-manifold, set up initially to
align the core optics. This ultimately gave a pretty good retro-reflection
of the IO beam off the recycling mirror, which we fine tuned by adjusting
the orientation of MMT3.
We then blocked the beam going to the X-arm, so that we had a cavity
formed by the recycling mirror and ITM-Y, with the beamsplitter inside
making the finesse very low. The angle of FMY was adjusted until we
saw
nice interference at the beam coming out of the anti-symmetric port
telescope -- at times the beam would uniformly flicker between bright
and
dark, though alignment fluctutations also produced varying spatial
fringes
across the beam (we're still in air!). Some time traces of the power
at
the AS port can be viewed at:
http://www.ligo-wa.caltech.edu/~pf/2km/*.pdf
We then tried to bring in the beam from the X-arm (using FMX), but
saw
only small increases in the stored power. Later, after the Y-arm had
been
blocked by the gate valve for pumpdown and we had again a simple cavity
formed by the recycling mirror and now ITM-X, we found that more pitch
adjustment was needed on this arm to get good alignment with the RM.
We were out of range on FMX, so by pitching the beamsplitter we were
able to see the same kind of interference we had seen with the Y-arm.
We finished by carefully misaligning the RM and dumping the RM reflected
beam into a pair of beam dumps, in preparation for the 2km cavity testing.
Unfortunately, this means we won't have another opportunity to see
interference in the power-recycled Michelson for a while. However,
as soon
as the diagonal section and X-manifold are pumped out, we will have
the
opportunity (prior to opening up to the beam tube) of looking at the
Michelson interference -- we will soon be able
to make the very
interesting measurement of the contrast in the
simple Michelson.

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
--------------------------------------------
- The current shunt actuator was installed on laser #107 at Caltech
by G.
Truong and S. Gomes of Lightwave Electronics. However two laser power
supplies, one of which was brand new, malfunctioned. For reasons unknown
four FETs in the laser power supply blew.
A possible cause is a ground path through the indium bonding
between a 20-W diode bar and the power amplifier cold plate. Whilst
this
has not occurred on any 10-W laser before, it has been apparently observed
in other Lightwave lasers. Both the laser and power supplies have been
returned to Lightwave for repair.
- Following the installation of the new low voltage PZT version of
the
pre-modecleaner (PMC) at LHO, there were reports of large intensity
fluctuations in the output of the PSL. The reasons for this are not
known but one possible cause is the epoxy bonding of the aluminum cap
holding the PZT to the fused silica body.
The intensity fluctuations were looked for in the output of the
LLO PMC and were not observed. Both PMCs are identical in construction.
- A reference cavity vacuum chamber has been repaired by Nor-Cal. Previously
during the initial cleaning and preparation for baking, it was observed
that
one of the ConFlat knife edges had a nick in it. The chamber is now
back
at LHO for cleaning and baking.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
UF weekly report.
Dave and Isabelle Reitze had a healthy 6 lb baby girl this morning.
Mother
and daughter are doing fine.
# DHS Congratulations!
In-vacuum Faraday isolator
Design of a subassembly module for the in-vacuum Faraday isolator is
complete and parts are being made in the shop. This is a small optical
aluminum breadboard on which the rotator, polarizers, and rotators
can be
assembled and aligned prior to insertion into the HAM.
WA-2k MMT alignment
Finally we have achieved good MMT alignment. The input beam is very
well
centered on RM (within <5mm) and gets retro-reflected, rejected
by the
Faraday isolator and sent to the symmetric port.
What is more, we also aligned the short Michelson/recycling
cavity and we
observed nice fringes at the output of the APS
telescope. A contrast of
(Max-Min)/Max = 90% has been obtained. Some neat
data traces will be
available soon.
We also measured the mode matching parameters of the 2k IFO input beam
using a large aperture (7") COS lens and a beam profile scanner. Data
will
be analyzed.
LA-4k installation
With the help of Janeen, Helena, and Gary, we continued preparing small
optics
suspensions. As of Nov. 10 the status is:
One Mode cleaner flat mirror has been balanced.
All six magnets, a wire standoff and a wire guide rod have been glued
to
the other mode cleaner flat mirror, two mode matching telescope mirrors
and
a steering mirror.
A wire standoff and a guide rod have been glued to the mode cleaner
curved
mirror.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
We are finished with SPETM07. The next optics to be processed (in
order) are BS, ITM for Livingston. We have learned more about the art
of keeping up with changeing room temperature using chilled water flow
as a control and measured tilt as a feedback.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
Assisted Janeen and Sany with suspension work (balancing, rebalancing
optics, preparing PAM magnets and OSEMS.
Inspection of epoxied springs in progress.
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE
All the production PO telescopes have been received and are being inspected
prior to shipping to LHO and LLO for cleaning and baking.
ETM TELESCOPE
All production ETM telescopes have been sent to LHO and LLO for cleaning
and baking. The AR coating on three lenses were damaged during the
normal
LIGO cleaning procedure. The lenses have been sent back to the manufacturer
for evaluation. Helena A. is revising the cleaning procedure for commercial
optics. The 2K ETMx telescope is being assembled by Betsy W. at LHO
for
installation on 11/15.
PO MIRRORS
Awaiting delivery of 4K LHO and 4K LLO PO mirror mounts.
VACUUM WINDOW
Widows have been installed in HAM10, BSC6. BSC5 window is being installed
prior to 11/15.
ARM CAVITY BAFFLE
Received partial delivery of production items for Inner Baffle, awaiting
balance. Received partial first article parts of the Outer Support
Frame.
The top assembly drawings for five arm cavity baffle configurations
have
not been completed. Glass has not been ordered.
CONICAL BAFFLE
All production baffles have been received at LHO. A conical baffle
was
partially installed in the cryopump at y-midstation, by John W. and
Betsy
W. The baffle was restricted by the cold shield inside the cryopump
from
opening to the designed diameter, so the fastening tabs on the baffle
were
inaccessible and will have to be modified at a future date. The conical
baffle in the x-midstation is expected to be installed on 11/15.
COS ALIGNMENT PROCEDURE
The alignment of the FMx, FMy, APS telescope, and RM mirror which was
done
on 10/18 was discovered to be in error with several unexplained
discrepancies. The alignment errors were attributed to several positioning
errors involving the autocollimator, the BSC7 optical table, and the
alignment targets. The alignment was repeated on 11/4. The COS
autocolliimator height at the x-manifold was determined with an optical
level, and the projected beam angle was established by autocollimating
from
the HR surface of the ITMx. The y and z position of the ITMx was measured
by means of a target placed on the LOS structure, and the BSC7 optical
table was moved in the y-direction to correct for a slight error. The
target in front of the RM was re-positioned both in the y and z axes.
Then
the FMx was re-aligned to project the beam from the x-manifold, through
the
ITMx, off the FMx, off the BS, to the target in front of the RM. The
target
was removed to allow the beam to transmit through the RM, and the beam
position was measured in front of the MMT3 on HAM7. There was a total
angular error of approximately 200 microradians in the beam direction
from
the RM to the MMT3. The APS telescope was realigned, and the previous
height discrepancy of approximately 15 mm was found to be eliminated.
It
appears that the corrections which were made to the alignment procedure
eliminated and explained the discrepancies which were noted after the
initial alignment on 10/18.
4K IO BAFFLE
Glass for the 4K LHO and 4K LLO IO baffles will be ordered 11/11. Awaiting
delivery of the production parts for the frame assembly.
4K ELLIPTICAL BAFFLE
Most of the production parts have been received for the 4K LHO and
4K LLO
Elliptical baffles, the remainder are expected to be received on 11/15.
The
glass has been fabricated and is in the process of being AR coated,
with an
expected completion date of 11/22.

- Completed the Alfi component
tree display.
- Implementation of Alfi
box edit access via the tree is mostly
complete as
well now, but must wait on Ed's graphics work in
order to be
tested more completely.
- Getting further up to
speed on C++ via an excellent book called
C++ for Java
Programmers which much more efficiently exposes me
to the parts
of C++ which I don't already know/understand.
[Hiro Yamamoto]
* Installed e2e on the computer at TAMA following the MOU attachment
for the simulatio effort. Gave several talks and demos
about e2e to
TAMA sicentists.
* Discussed with Mr.Tomaru and Prof.Ohashi about the FFT simulation
of
TAMA IFO including the measured phasemap.
* Discussed with Anthony about the LSC implementation in the LIGO model.
* Discussed with G.Cella about the development and future collaboration
of the mechanics simulation.
A single suspended mirror calculations will be used to
validate the code
outside of e2e, and then integrate into the standard e2e
package. A strategy
of linking or exlcuing Cella's mechanics library was discussed
including
E.Maros.
LIGO Data Analysis System
[Masha Barnes]
* (MB) 'Table' element support for lwAPI:
- Added "units" attribute to the
'lstring' element in ilwd.
- Added support for 'lstring'
with units attribute in the lwAPI.
* (MB) Finished modifying lwAPI to use hash_maps with function pointers,
tested on Solaris and Linux -
works.
* (MB) Changed getLwTOC command in lwAPI to use different output format.
* (MB) Creating C++ classes documentation for lwAPI.
[ Phil Ehrens ]
* (PSE) Added command "dataSend" to the generic API which
can be used to send frame
and lightweight document files,
LW document objects, ilwd
text files and strings,
and c++ object pointers
(ilwd element and container,
frame, and LWDocument types
are all supported) through
ObjectSpace data sockets.
* (PSE) Added command "ligolw::all2lwp" to the ligolw
(lightweight API) to convert
frame files, ilwd text
files, LW document files,
ilwd strings, and c++ object
pointers to lightweight
document objects.
* (PSE) Added sanity checks to the frame API which parse the
most recent frame file and
make a log entry describing
global file attributes useful
for debugging the frame API.
* (PSE) Modified appropriate files to fix errors in the
documentation generation
for the various API's.
* (PSE) Added doumentation to the frame API c++ code, parts of
which were incomplete or
absent.
* (PSE) Supported Mary Lei in the development of user commands
which make use of the data
sockets and the rudiments of
the lightweight API.
[Grace Hu]
* (GH) Updated dynamically creating new group communicator - fixed most
errors which show
on screen.
* (GH) Created new programs for master processor distributing an array
and
letting slaves processors processing
FFT transfer.
* (GH) Almost finishing writing commont on C++ source code.
* (GH) Still working on adding more parameters on "mpirun" command.
[Mary Lei]
* (ML) Created tables at LSC database llo_1.
* (ML) Updated element test scripts to use a host name
when creating data sockets
since at the sites
the gateway (dataserver)
has 2 port numbers and
defaults to the external
port.
* (ML) Updated sock.tcl to use a local host name obtained from
resource file when creating
server and client
data sockets. This is because
gateway machines
have dual network cards
and the default IP
address is the outside one.
* (ML) While testing sending data between metadata and lw,
got a core dump in metadataAPI
shared object
at the binaryinspiral query.
Later
retest with Ed's metadata
so after he fixed the
problem: not handling null
data in result column.
* (ML) Added a function to ligolwAPI tcl to output LW doc
from ilwd object. Move handleDataSockCmd
into
ligolw.tcl to do data receives
and execute command.
* (ML) Ran element tests for data sockets at LSC and LHO.
Got consistent results.
* (ML) Updated all tcl scripts, pkgIndex.tcl and resource
files to change lwAPI to
ligolwAPI.
* (ML) Tested multiple queries for getMetaData with returnformat
set to LIGO_LW using metadataAPI,
ligolwAPI and
managerAPI. Threading works
most of the time but
there are cases where the
thread gets timed out
without connecting. Better
synchronization is needed.
[Edward Maros]
(EFM) Corrected metadataAPI to handle null data being returned
in binary data sets.
(EFM) Fixed configure.in in api/lwAPI/tcl and api/metadataAPI/tcl

additional 8 new trips in various stages pending completion of travel
arrangements before the paper work can be completed. Also worked
on a number
of problem issues which required a good portion of my time.
Completed 45 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
on a number
of problem issues associated with these which required a good portion
of my
time. There are 22 Expense Reports still to be done, including
1 that requires
extensive work to complete. I'm holding 5 completed Expense Reports
which
require a check from the Traveler before sending to Travel Audit to
clear.
Rita Torres through Liz was able to complete 5 Expense Reports for me.
She has
an additional 3 Expense Reports in the process of completion.
Thanks Rita.
I hate to have to continue to say it, but I continue to push for both
Advance
and Expense Checks already submitted. "The System" continues
to be extremely
slow in processing these. I'm still waiting for 7 Advance Checks
that I
ordered for my receipt starting Oct. 29th thru Nov. 3rd. Again,
I am still
waiting for T numbers. The new forms still take approximately
3-4 times my
time to complete and there is no way changes or corrections can be
made which
requires me to redo many trips and cancel out the original. Again,
this takes
time.
Performed normal recording and filing associated with Travel and
Reimbursement.
Made last minute changes for travelers going to the LIGO Inauguration
Celebration. I continue to monitor all the trips planned and
assist wherever
possible.
Travel for the PAC7 Meeting to be held at LIGO/MIT from Nov. 18th through
Nov.
19th has been completed. If there is anyone still not booked
please do so
now.
Prepared the Travel/Vacation Itinerary for the Week of November 1, 1999.
Performed miscellaneous duties as requested by various members of
the LIGO
Project here at Caltech, as well as from members of the staffs of each
of the
two (2) sites. I continue to do MIT's travel to the sites
for installation
activities and assist them wherever possible.
