Weekly Report Highlights

Flashes in the mode cleaner?


LIGO Hanford Observatory (LHO) Operations


General:
--------
(F. Raab)

This is a very busy week with lots of activity but not many incoming weekly reports! To summarize, optics are being mounted; baffle parts are baking in our
extended-size bake oven; mode-cleaner alignment work has been going on; the PSL E2E model is being worked heavily; and Doug Cook has been living in BSC 8,
where a folding mirror is now hanging. Richard Helms has begun his SURF appointment and our SST teams from Gladstone High School and Kamiakin High school
are getting in the groove. Prediction: there will be a longer weekly report next week.
 

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

BSC 6 (Y-Mid): The alignment of the Adapter Plates has been completed and the remainder of the stack can be installed.  This may have been done (by Lee
Cardinas or others) this week.  There is only the Scissors Tables to be installed though; we are waiting for the next stage (X-Fine Translation Stage) which are still at
the Fabricator.  We expect these mid to late next week.
 

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

A new 18.2 GB internal disk drive has been installed on rainier.  This
has created more space and allowed me to install all the OS recommended
patches as well as some other patches for Y2K and for the Workshop
compilers.  I have been able to spread user accounts around to allow
more space for each user.

I am working on GC web pages that will show disk layout, server
health/status, etc.  I hope to have the first pages ready by Monday.
There will be a link to the GC pages from the Ligo Hanford home page.

I also did the usual weekly backups, reconciled expenses, added several
more user accounts, helped with some email problems, met with the LDAS
Installation group, attended a meeting on furniture layout for the
Computer User's Room, ordered more GC supplies, and installed Secure
Shell on the Guest PCs and setup each of the Unix workstations to run
SSH from rainier.
 


LIGO Livingston Observatory (LLO) Operations



 

Detector Installation: We have begun BSC 3 seismic system installation. This week the air bearing assemblies and cross beams have been installed. Also, the dome was removed and the roller system was set up for use in installing the support tubes. The D nozzles have also been removed. All of the platforms and railings have been installed in preparation for support tube installation on Friday. (Rich Riesen)

Optics: Jonathan worked with Hugh Radkins and machined several components for his survey fixturing. Received and installed two additional flow benches for the vacuum prep lab. Had leveling feet fabricated to square our four flow benches, compensating for the inclined floors in the lab areas. Leveled same. Made fixturing and began coil winding for Mark (These are a set of 4 coils that we will use to measure the second derivative of the magnetic field inside the BSC to determine the magnitude of the second difference magnetic field at the mirror point - Mark) (Jonathan Kern)

Beam tube bakeout: Power has been established to the bake transformers and phase has been checked. The data cables for bake have been run and the data system is in installation and testing. The job walk was held for the electrical contractors for BT bake. We are currently installing pumps for the BT bake. (Allen Sibley, Kerry Stiff)

Facilities: A pre-contract conference (Job Walk) was conducted for the proposed Landscape and Erosion Control work at Livingston. Six potential contractors attended the meeting (a seventh contractor indicated he would submit a proposal, but could not attend). A number of questions were raised. Formal documentation providing the answers to these questions is being faxed to all participants.

Weather Station Problem with checking software fixed. Consultation and discussion with Campbell scientific engineers yielded another potential solution to the high error rate. The idea is an interface box converting TTL to RS232. It has been installed and is currently undergoing testing. At this point, it does not seem to fix the problem. We have discovered that the problem is related to opening and closing the CSI port(the port used by LSU). (Anthony Rizzi)

GRASP Seismometer fixture put down under tile floor in mass storage room. Since water still leaks into the floor a water-tight fixture was made to keep any water far away from siesmometer. We are now testing the fixture in situ and monitoring humidity.
Seismometer data has been successfully ported to GC side and looked at with animateF. Opmtimal F still not functioning correctly with LIGO data. We need to understand how to implement swept sine calibration for LIGO. (Anthony Rizzi)

CDS: The cable tray installation at the corner station is complete. The cable tray installation at the south end station is ~50% complete. In the EE lab, we received a new PC and finished window 98 installation. This PC is already on our network. Plan to install LINUX in the 2nd hard drive for data acquisition system. Found some useful information for people who use HP deskjet printers to print data from Tektronix scopes. Those HP printers have to be 600 series. 700 series won't work at all. Lab inventory needs to be updated. Many instruments are no loner on the lab shelves, instead they are kept by people for many months. The lab ends up not to have enough equipment for other people to share. If anyone has borrowed instruments for several months and is not using them at the moment, please return them to the lab ASAP. The LLO CDS web site is done. There are still some
details needed worked out with D. Barker. The hardware inventory is ready for people to use.
 (Rusyl Wooley, Julien Svoboda)

Bakeout oven: We have borrowed a rough pump to replace our old one, which was failing, and are currently baking small parts for the next chamber to be opened. (Tom Evans)

Computers: We have received a backup tape drive and IslandDraw. We are still waiting for prices and information from vendors for several other packages. (Tom Evans)

Interferometer Sensing and Control -- P. Fritschel
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
 

IAS Initial Alignment (K.Mason, M. MacInnis)

Both Myron and Ken are at Hanford aligning FMy and ITMy large optics.
Trouble was encountered in
aligning FMy. The reflectivity of the HR surface was approximately 7%
which was less than the 14 - 20 % we had anticipated. With double
reflections off the Fold Mirror the
total power returning to the autocollimator was less tha 1/2%. We were
able to correctly position the Fold Mirror. In order to align FMy in pitch
and yaw a new plan was
created which places an optical flat in such a position to allow a single
reflection off the Fold Mirror. We will be setting up for this alignment
6/17 thru 6/18. Alignment of ITMy will now be put off until next week.

Mode Cleaner Installation (P Fritschel, N Mavalvala)

PF, Nergis & Rana have been at LHO setting up the mode cleaner,
working with UFl folk until their departure:

Initial (in-air) alignment of the mode cleaner has been proceeding
slowly over the last week, and at last we have reached a point where
we are seeing fringes on the transmitted beam. There are numerous
problems that we encountered along the way, and have more or less
found solutions for them. The most significant change that we made
was to increase the range of the mode cleaner mirror suspension
controllers by a factor of 4 (by decreasing appropriate resistances
in the modules). This was done after finding that the accuracy
of the pitch balancing, and the precision with which the yaw angle
of the suspension tower can be adjusted, were both just too poor
to enable us to align the optics within the original controller
range. Increasing the controller range makes a dramatic difference
in our ability to align the optics, and a relatively insignificant
increase in the noise budget of the mode cleaner. We are now
proceeding to fine tune the alignment of the mode cleaner using
the suspension controllers.
 

ISC Tables (M. Smith)

Finished the design for the ETM transmision monitor enclosure.  All
parts are out for quote so that they can be bought before next weeks
deadline.  One thing that remains is the design of the packaging for the
quad diode box. Purchased one set of optics for the ETM transmision
monitors.

Made the changes to the IAS table enclosures to fit the new beam
positions.

Supplied Hanford a drawiing to locate the holes for the optical lever
platform for the Y-MID station.

Sent out the riser blocks to the optical lever photodiodes to be
reworked for the isolator bushing.

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 double-passed output of the frequency shifting acousto-optic
modulator has been mode-matched to the PSL reference cavity, after much
grief during the alignment process.

    The 10-W laser has been locked to the reference cavity.
Examination of the in-the-loop noise spectrum reveals high frequency
oscillations, indicative of an incorrectly adjusted cross-over to the
Pockels cell actuator.  The high frequency oscillations could only be
removed by maintaining a low bandwidth lock to the reference cavity.  The
frequency stabilization servo is currently being debugged to find the
cause of these oscillations.

- The pressure in the PSL reference cavity vacuum chamber continues to
improve (as it should).  Currently the pressure is ~6e-9 torr.

    The MINCO process controller is now regulating the temperature of
the reference cavity vacuum chamber.
 
 

Input/Output Optics -- Dave Reitze, UF
-----------------------------------------

Hanford 2-k IOO

We have finished placing and aligning all the IOO components on PSL/IOO
table at LHO. Apertures and beam tubes (temporary plastic tubes) have also
been placed. Beam shape measured behind the periscope bottom mirror
(actually after the first corner mirror in the optical spectrum analyzer
beam path) by a beam scanner shows the same ellipticity and errors (from
Gaussian, for x and y) as those measured at the PSL/IOO hand-off point.
This beam quality stayed unchanged for two days.

Protective covers for mirror mounts which will prevent accidental
misalignment of the PSL beam have been machined and are being anodized.

Mode Cleaner Alignment

Progress has been made on the MC alignment, due to the efforts of
Guido, Haisheng, Nergis, Rana, and Peter. The initial balancing of MC3
and possible changes in balancing due to transportation of the MC
mirrors from the optics lab to the LVEA caused some problems in getting
the beams aligned.  The dynamic range of the SOS controllers (~ 1 mrad
in pitch and yaw) was insufficient to complete the alignment.  Of the
possible solutions discussed (such as trying to rebalance the optics
in-situ), we opted for the electronic solution of changing the dynamic
range of the SOS controllers which will allow for greater angular
adjustment without much sacrafice in noise performance.  This has been
implemented and the alignment is underway again!
 

#DHS: We have heard through the grapevine that there have been 'flashes' of
light from the Mode Cleaner on thursday afternoon. Great News.

LLO 4k

In-vacuum, nonsuspended mirror mounts are being machined in the UF
machine shop.  Sany will travel to LHO to prepare the PSL table IOO
optics.
 

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

We have not been able to start on measurement of SPETM04, the last of the
Hanford 2K optics.  This is due to instability in the lab temperature,
which is probably caused by the changing weather outside here in Southern
California.  After 10 days of trying to get the lab temperature within 1/2
degree C of 20C, as of Thursday morning we think we have it.  At least
until the weather changes.

Rai Weiss is kindly taking time out of his busy schedule to work with us on
discovering the exact cause of the temperature sensitivity.

Achim Leistner and Bob Oreb of CSIRO will be visiting LIGO Monday July
19th.  At that time they will have the opportunity to look at 4ITM01, which
was not coated because it had marks which could not be cleaned with the
known methods.
 

Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO contract - COC's coatings. The coating of the COC's is approaching the
end and the more we look at these parts, the more we learn. The more we
learn, more we see.
We proved the known notion that optics have to be coated immediately after
polishing. The ITM's recently received from CSIRO cleaned very fast. The
SPETM's that were stored for months were very, very hard to clean.
We see faint streaks on the uncoated parts that are impossible to remove by
conventional cleaning methods. We see these defects on CSIRO optics (one of
them pretty bad, we did not coat it) and we see them on parts polished by GO.
We inspected all optics after coating, before baking them. They were also
cleaned and looked at, prior to baking. All defects were noted, such as the
faint streaks. The coating specs were met without problems (reflection and
transmission).  We finished four SPETM's and three 4kITM"s. Two more 4kITM's
are getting their AR coatings at this time.
 

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

PO TELESCOPE
REO has received 4 secondary mirrors for coating on 6/18. Ken M sent out
bid packages for the PO telescope.

ETM TELESCOPE
We have received a few quotes for the ETM telescope production.

PO MIRRORS
The SS tilt screws have been electropolished and are awaiting testing.

CAVITY BEAM DUMP
The remaining part (angle bracket) is expected on 6/17 AM, which needs to
be fit checked to a vertical support tube. Thanks to a heroic effort by Ken
M., Steve E., Craig C., Dennis C., and Mike S., all the other parts for the
beam dump assembly in BSC8 were cleaned and packaged ready shipment. They
will be shipped for arrival at LHO 6/18 AM. The angle brackets and the
held-out vertical tube will be cleaned and shipped for arrival at LHO 6/18
AM.

VACUUM WINDOW
Varian has sent a first article of the re-made con-flat o-ring groove parts
to Jonathan K. for evaluation.

COS IR ALIGNMENT BEAM
IR laser source is expected to be shipped 6/30.

ARM CAVITY BAFFLE
Paul K. is detailing the arm cavity baffles.

The Chart that we provided last week did not show up because of pointer problems. I am including it this week, hopefully with better success. We did an analysis of the Invoice Processing history based on information provided by Dot. The chart summarizes the data for the past year and a half. Note that while the dollar value of invoices processed has decreased, the volume has steadily increased and shows no immediate signs of abatement.

Finishing the monthly reports and getting ready to distribute them (the last of the IFIS data (maybe)).  Investigating for errors and trying

>From Stuart Anderson,

        Worked with the LDAS group and Daver Barker at LHO to build the
LDAS ATM network at LHO and integrate it with the existing CDS network.
See http://www.srl.caltech.edu/personnel/sba/ligo/atm
for a picture of the topology and initial network performance numbers.
We where successful in accessing the current frame disk cache from the
CDS server over ATM.

        Updated the Solaris patch level on the CDS frame builder to
increase its stability and fix a known problem that hung processes
that accessed one of the virtual memory interfaces, e.g., ps or netstat.

        Reported Linux nscd bug, received and applied patch to the LDAS
linux machines running NIS+ to solve a name server caching problem.

        Fixed hardware problem on spica that resulted in reduced SCSI
performance and reliability.

        Compiled, installed, and tested an Alpha release of ATM support
for Linux on the new LDAS/LHO ATM network. The test hardware has been removed
and further stability testing will take place at Caltech.

General Computing


MIT:
Sean Scanlon is visiting MIT from Caltech this week. He did a preliminary security check
on some of the systems and found them to
still be in pretty good shape. He installed the SUN patch tracker and has the
information forwarded so we can make sure the latest patches are installed on
the units.

Livingston:
Nothing to report.

Hanford:

A new 18.2 GB internal disk drive has been installed on rainier.  This
has created more space and allowed me to install all the OS recommended
patches as well as some other patches for Y2K and for the Workshop
compilers.  I have been able to spread user accounts around to allow
more space for each user.

I am working on GC web pages that will show disk layout, server
health/status, etc.  I hope to have the first pages ready by Monday.
There will be a link to the GC pages from the Ligo Hanford home page.

I also did the usual weekly backups, reconciled expenses, added several
more user accounts, helped with some email problems, met with the LDAS
Installation group, attended a meeting on furniture layout for the
Computer User's Room, ordered more GC supplies, and installed Secure
Shell on the Guest PCs and setup each of the Unix workstations to run
SSH from rainier.

CIT:

Worked a number of PC issues. We are preparing for the training session on the
new accounting system. A number of PC's are being installed on the 6th floor of
Millikan for the training sessions. Samantha is rebuilding the machines at this
time.

We are still battling the "HAPPY99.exe" virus. There is also a new virus out
that comes in the form of a zip file and is worse. We are getting the latest
data on it so we can try and get the PC's loaded with the correct anti-virus
modules before we get hit.

Suresh is going through old accounts that have not been used for a long period
of time and cleaning them off. The accounts and the associated data are being
put to either tape or CD, depending on the ammount of data.

Peformed a couple of disk swaps to recover from some disk problems we were
having on the servers.

Everyone is working on documentation.
Barbara is working a number of web issues. We hope to start making changes on
the web configurations next week. One of the disk drives we have been waiting
for has arrived.

Doing a lot of recabling in the server room and trying to get it ready for the
installation of the new router.

Worked a number of procurement issues. We have been trying to get as much
cleared up as possible before the CIT accounting dark-period which starts this
week.

Repaired the temporary glitch on the mail-server. We had to go to the backup
server for a short period of time and it appears the main problem from the
switching was duplication of e-mail and some machines needing to be rebooted.
We also rebooted ligo just for the heck of it. It had been a couple of months so
we did it just to clean up all of the processes.

A number of new accounts have been added for SURF and visitors.
Also, working some of the logistics for the Amaldi Conf. with Syd. We are
looking into what it will take to have a computer pool for the visitors to use.

Due to Caltech's conversion to a new Accounting System, there will be a "Dark Period" during which nothing new will be able to be processed. You are encouraged to make travel arrangements for your upcoming trips from now until August TODAY or be prepared to purchase tickets using your personal credit card. This "Dark Period" is scheduled to start on June 16th. HOWEVER, I have set my personal goal as close of day on Friday, June 11th, just to make sure I get your trips done. This also applies to Expense Checks and Advance Checks. Thanks for your help. With your assistance we should be able to get through this.

Due to the overwhelming amount of new trips I concentrated on the paper work involved for new trips first then worked on Expense Reports. I completed 33 new trips (31 Purchase Requisitions and 33 Advance Requests) as well as all the necessary additional arrangements required for them. I still have 9 more to work on, with the promise (or threat) that I should expect approximately more today. I plan to finish with all the new trips first, then put my undivided attention to the Expense Reports I've received this past week.

I worked on and completed 22 Expense Reports. I have 34 Reports to go.

Prepared Travel/Vacation Itinerary for the Week of June 14th, 1999. I also attended an Oracle Orientation Meeting on Payroll and another one conducted by Ed Jasnow on the overall scheduling of Oracle Classes for LIGO personnel. Assisted in scheduling the Millikan Conference Room for the entire week of June 21st to conduct classes for the LIGO Adm. Staff.

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.

Dorothy Lloyd

Continued working on closing out inactive contracts and POs in IFIS in preparation of moving over to the new system Oracle. Managed to work a little on reconciling status reports. Process heavy load of invoices for payment, and tracked and followed up on various invoice problems. Signed off on numerous PO receivers. Processed the usual heavy load of POs, reqs, change orders, check request, etc. For further details see Cost Schedule Control System Report by Sarita Moore.

Elizabeth K. Wood

Contacted George Weal, the air conditioning guru in Physical Plant, about the tropical conditions in room 18 (computer room). He's supposed to get back to me today to examine the unit to determine what improvements can be made, especially in light of the new machines that will soon make their home in room 18.

Worked with the division office on upcoming space issues and began assigning office space to projected visitors and postdocs for the coming season.

Handled on-going personnel issues.

Helped Dot with sorting and filing purchase orders.

Oh joy, we have located enough PCs for the administrative staff to be trained on the new ORACLE system(s). Please be patient if you can't find any administrative staff during the week of June 21. As much as we'd like to run, we can't hide.
