>From: Linda Turner - turner@ligo.caltech.edu>

Web pages for the DCC give simple how-to's for document numbering, easy access to the latest on-line documents, and search capabilities for the DCC database.Take a look. . .

ACTIVITY HIGHLIGHTS

• Work continued on updating a status report for Process Travelers.  Numerous drawings referenced in travelers have either not been submitted to the DCC and/or have not been formally released with a DCN.  A composite listing of these drawings is being assembled as I work through the stack of process travelers.
• A final organization of the CB&I Assembly Data Package was completed.  The entire data package was assigned one DCC number but was divided into multiple volumes.  This data package is organized by assembly number, joint expansion numbers, and also contains all Material Test Reports (MTRs) and vendor certifications.  An additional set was made for the Hanford Observatory so it would be readily available as needed.
• With new filing space, made good progress in filing backlogged documents.
• An email is being drafted that will be sent to authors who have reserved "P" numbers for documents that haven't yet been submitted to the DCC.  Hopefully, this will reduce the number of documents missing and serve as a reminder for those who may have forgotten to submit a particular publication.

• Electronic documents continue to come in at a regular pace.  To help keep the process streamlined and timely for everyone:
• File naming should be based on the root part of the number plus the revision and without the Group ID.  Additionally, the file name should be in capitals, and the format extension in small letters.  Thus a document numbered as
• LIGO-G990025-00-D would have a file name of G990025-00.pdf
• All pertinent information needs to be on every document.  This includes:
• DCC number
• Author's name
• Date of document
• Title
• Duplicate submittals can be confusing as well as time consuming.  If you can't remember whether a document has been submitted to the DCC, you might check the docspublic directory to see if it resides there.  Or, feel free to give us a call so we may check for you.

LIGO Hanford Observatory (LHO) Operations (Raab)

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

At 10 AM, Friday, October 20, Barry and Stan announced "First Lock" to
a crowd of newspeople and invited guests in the Multipurpose Room at
LIGO Hanford Observatory. In the meantime, commissioning efforts raged on.

Optics:
-------
(D. Cook)

The ETMx-4k & ETMy-4k core optics are processed and ready to be fitted with
OSEMs. The MMT3-4k & ITMy-4k core optics are in the vacuum bake oven and
come for final suspending on Monday. The ITMx-4k core optic will be
balanced by Monday and into the next bake load. Processing of the RM-4k
core optic will start early next week. We have received some additional
installation/commisioning support equipment with more on order. Rework of
the PAM brackets and screws continues. 4k installation staging contues.
 

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

Due to security reasons FTP had been turned off to all computers at
LHO.  LDAS now needs to have FTP turned back on for Anonymous FTP to
their data server.  I have modified the access list for the router to
the T1 line to allow FTP only to the ldas.ligo-wa computer while still
denying FTP to all other computers on site.  I will coordinate testing
this with Greg Mendell.  All computers on site can FTP out they just
cannot be FTPed to.  The preferred method of file transfer is still scp.
 

The user account backups have been going well and are completely
automated using the Quick Restore software.  The evaluation period on
the software expires in 10 days so, I will be writing a PR to buy the
software.
 

LIGO Livingston Observatory (LLO) Operations (Coles)

OPTICS/COC/SEI INSTALLATION: The leaking NW bellows has been removed and replaced on BSC-4 at the X-end. The West and North BSC doors have been removed, and the LA-1E flange at GV-12 has been removed for Allen to inspect o-rings. We've resurveyed and double-checked all IAM monuments in the X-end. Axial position of ETM-x has been measured and it is incorrect (As expected. The wrong prism constant was used at installation). We'll setup the IAM equipment this week and properly position and realign the optic. First we will install and assemble the Arm Cavity Baffle, align it and then remove and store it for permanent installation after arm lock. Obtaining laboratory equipment bids in the new lab for Fred Asiri, as well as quotes for the outdoor cover for Mark. Began in earnest to vacate the shop area in the Staging Building. Edited new Laser SOP and began draft of IOT/ISC table Laser Safety SOP. (Jonathan Kern)

Detector Installation: IOT1 has been cleaned up including all its cabling. The RAMP signal from the GPS timing boards makes it possible to determine the exact time of the GPS second tic relative to the time stamp of the DAQ system. We examined the signals between the Timer and the filter box, the filter box and the ADC and in the recorded frame. Up until the ADC the signals are perfect as they should be. Unfortunately the filtering in the ADC introduces large oscillations around sharply falling or rising edges which strongly distorts the signal and makes a large part of the ramp unusable.  An example of the offset for the 1x5 crate is ~42 us with a ~50 ns jitter and estimated ~0.5 us systematic error due to the uncertainty of the ramp shape (filter distortion). The error on the GPS edge is ~150ns with the new receivers. (Joe Kovalik)

CDS related: Installed all field cables for the alignment and the length sensing & control. Installed and terminated all cables required for the frequency distribution system. (Rus Wooley)

Vacuum: Leak check in the LVEA continues. No leaks have been found thus far. Pressure in large volume continues to improve. New o rings are being  installed on the north door and the spool piece on the X arm end station to correct leaks found earlier. The leaking northwest bellows assembly has also been replaced. (Allen Sibley)

1.1 LHO INSTALLATION & COMMISSIONING

2km Commissioning

(a) We see that the resonant spot in the X arm drifts away (misaligns) as the interferometer comes into resonance. This has been traced to saturations and slew rate limits in the coil driver circuits and possible fixes are being worked on.

(b) A 4.4 kHz noise peak was found in the common mode arm cavity signals. Since the coil driver saturation problem (above) is exacerbated by this, we chased it. This was isolated to be in the input of the Pentek 6102. There are two 6102s in the LSC front end digital crate, both with higher than expected noise, and one with the 4.4 kHz peak. We have not been able to replace the offending Pentek yet, but decided to circumvent the problem by increasing the gain for the signals before the Pentek.

(c) To get higher gain for the front end signals we increased the light on the reflection port photodetectors, so we could run at lower gain in the digital system. This has exposed saturations in the front end which cause very poor locking of even the power recycled Michelson. These are being investigated.

(d) We observed saturation of the photodiodes that detect the arm cavity transmitted light when the carrier builds up in both arms. A careful setting of gains was done to keep the noise level in the non-builtup light power level at an acceptable level and yet have the dynamic range to not saturate at full build up.

(e) The frequency noise from the PSL/MC was measured to determine if it was at an acceptably low level for the carrier double resonance. We found that frequency fluctuations around 5 Hz were at the level of 300 Hz, equivalent to ~2nm of arm cavity motion (cavity itself is probably much more stable than 2 nm at 5 Hz). En route to this measurement we tweaked the MC servo to minimize the frequency noise as well.

(f) Finally, we have remeasured the lock acquisition coefficients for the calibrations/normalizations with the various hardware/light level changes so we can attempt full locking again shortly.

SUS 4k (Digital)

LOS coil driver chassis drawings have been started and should be complete by 10/25/00. LOS Coil Driver circuit boards are due back 10/20/00.

LOS Bias module board layout has been completed and should be sent to PCB vendor by 10/20.

SOS Dewhitening schematics are complete. Board layout should begin this week. If it does not it will have to wait until Jay gets back from LLO.

Optical Lever PD Boards

PSL

Lightwave queried me as to why we sent back power supply #108, since they tested the power supply and found there was nothing wrong with it.  After clarification from Richard McCarthy --- I had thought the problem was related to the mains fuse blowing --- I relayed the problem to Lightwave. The problem with the power supply is that it was extraordinarily sensitive to trip outs, more so than other power supplies.  This is despite disabling of the over-voltage protection circuitry.  Lightwave agreed to test the power supply as before, except instead of leaving it alone all the time, they would randomly touch the power supply to see if it would trip out.  One suggestion they had was that we try to remove the anodizing behind the ears that enable the power supply to be bolted to the electronics rack, in order to improve the grounding.

More PDA-55 photodetectors, typically used to monitor the pre-modecleaner and reference cavity transmission, have been modified and checked out.

1.2 LLO INSTALLATION & COMMISSIONING

Optical Metrology

PSL

Rick Karwoski, Paul Russell

We continued our efforts to provide light sources to Hanford, MIT and 40m lasers . Specifically in preparation for assembling the PSL at Hanford, six of the seven required VME modules were sent to LHO.  Additionally Richard M. has received the following: Rack netlist, Rack layout, Field wiring definition, required FLKM; LHO can begin assembly.

Missing in action are one VME, one Euro-crate and one VMIC 3113 VME module. Resolution of these deficiencies is in process.

We are in the process of scrounging components for the pre-mode-cleaner servo from the Wilson House supply. Once we have them we will begin stuffing boards for the Hanford Laser.

Electronics BOM (bill of materials) completed for all modules in the PSL

Electronics parts are on order for Hanford, MIT and 40m lasers.

The lab (room 254 West Bridge) is slowly coming together. Ordered an ESD parts cabinet manufactured by LISTA (5 week delivery.)

ISC

Mohana Mageswaran, Flavio Nocero, Rich Abbott
Mohana finished the PCB layout of the MC Servo Board and is now doing the PCB layout of the Elliptic notch filter daughter board which goes along with the MC Servo Board. A 14.7 Hz notch filter is being incorporated into the design by Flavio.

ISC Frequency Distribution

Optical Lever PD Boards

Data Acquisition

Continuing work on putting an interface to the dataviewer to directly access frame files, thereby allowing data to be read from an offline file system. First version should be running next week.

Working on porting Analog Data Collection Unit (ADCU) software to a Pentium-III processor. This is for new systems to go into the 40m and LASTI, as these processors are faster and cheaper than the MIPS used in present systems. Last hangup is block transferring data to the DAQ controller, which presently gives errors.

Added some mods to the DAQ controller code: 1) Reports synchonization errors separately from other errors; 2) Appropriately marks data status fields.

Modulated OSEM Design

New OSEM Heads

Janeen Romie
Progressive Technology to deliver alumina heads  on 11/7/00. Surmet is planning to deliver on 12/22/00. Working procurement for associated parts and services.

Global Diagnostics

diagnostics test tool: type "dtt" The setup is similar to the one on fortress; in order to read off-line data you have to choose the Setup option from the main menu and select a directory containing frame files.

data monitoring tool: type "dmt" This will bring up the interactive root environment.

data viewer: type "dv" (not very useful at this moment.)

guild: LDAS database access: type "guild"

Sander Liu, Dave Grimmett
Received the SMA connectors from Pasternack. Still waiting for the LEMO connectors. Dave has finished modifying most of the printed circuit boards to change offset adjustment range. Expected to start testing them early next week.

2.2 Issues Concerns

40 Meter Interferometer (Weinstein)

• Vacuum control system: Ben has protel vacuum wiring diagrams on his web page. Dennis Ugolini is writing the EPICS code for controlling the pumps and valves from the EPICS GUI, and testing them on a valve that can be opened and closed without disturbing the system. He's writing the code for the software-based interlocks. He's finishing the wiring of the remote valve control boxes and cabling. Then he'll hook everything up and test it all out.
• Preparations for STACIS installation: The first of four sets of STACIS isolation systems is expected to be delivered any day now. Steve Vass, with help from Dennis U, has removed the feet from the south end chamber stack supports, and is supporting them temporarily with steel support bars (to be replaced with the STACIS cradles). They took care to measure the motion of the load, and kept it under 0.0055". The floor tiling is being removed, in preparation for grouting steel plates on which the STACIS pedestals will rest. This whole procedure took most of the week. It must be repeated for three more chambers, before installation of the STACIS cradles and pedestals can begin; Steve figures this will take less than two more weeks.
• The output optic chamber has been pumped on for 70 days. It is now vented. The RGA that monitored it has now been successfully calibrated, and it looks like the outgassing rate for known oil by-products (AMU = 41, 43) is no larger than that for the entire 40 meter (we still need to review the numbers, but a preliminary document can be found here.
• Janeen is buying OSEM parts for LIGO I and also for the 40m.
• Garilynn is awaiting wedge determination for mode cleaner flat mirrors; awaiting radius of curvature for mode cleaner curved mirror (AJW will supply that shortly!), pestering glass vendors (Corning and Heraeus) for quotes, and preparing an RFQ for mode cleaner flat mirror polishing.
• Ben Abbott, Jay Heefner, Rick Karwoski, and Dennis Coyne met and discussed possible rack layouts, and reflective memory layouts, for the 40m lab. Ben has protel rack layouts on his web page. It should be emphasized that they are 0th order designs that will change as the designs for LIGO II change. Preliminary decisions:
• Separate DAQ and ISC reflective memory networks are required.
• Separate X and Y arm reflective memory networks are required in LIGO due to the long light propagation times down the arm and the uni-directional loop arrangement of the reflective memory networks.
• A total of 12 electronic racks are required for the 40m lab: FB, PSL1, PSL2, ASC, LSC, SUS1, SUS2, DAQ, PEM, Spare, Xend, Yend. The rack order will be made by Jay or Rolf when they order for LASTI this month. We will also buy some VME crates, but not many since we won't know exactly how many of which types are required for some time.
• Rick Karwoski is continuing to update his diagrams and tables for 40m CDS, ISC, suspension controllers, LSC, ASC, etc.
• Dennis Coyne has created a set of AutoCad files using Mike Smith's optomechanical layout, and the building and power distribution drawings, that will be used for a set of integrated layout drawings to be maintained for the 40m lab.
• Dennis C. has started checking Alan's proposed cavity lengths and modulation frequencies.

Thermal Noise Interferometer (Libbrecht)

This week we installed all four of our test optics, and we installed the
in-vacuo mounts for the optics leading from the mode cleaner to the test
cavities.
 

Satellite amplifier boards are now complete and tested.  Many thanks to Jay
and Shaun for all their help!
 

LASTI (Zucker)

Special problems: A 2" hot water line broke in the hallway above
the LASTI high bay Tuesday and flooded part of the lab.  Fortunately there
was little damage and the flooding did not affect the cleanroom
area near HAM-13, which was open (with socks) at the time. We cleaned locally
to enable finishing the ongoing installation; a professional
crew will be brought in to reclean more globally after things
are buttoned up.

Having lost a little over a day from this incident we decided to try and
finish the
HAM13 internal components
installation so we will have done a complete
chamber while Corey and Hugh are still available.  Thus trained we will defer
moving on to HAM20 and HAM21 to finish later on our own.

PSL: Peter King reports the optical table for the LASTI PSL is on
order.

GDS/DAQ: Rolf Bork reports orders went in or are ready to
for most GDS and DAQ hardware.

Pier marking is underway

Data Analysis and Computing (Lazzarini)

Simulation and Modeling (Hiro Yamamoto/Biplab Bhawal)

There is e2e workshop going on from Wednesday (18) to Friday(20).
Presentations were given on Wednesday, which covered the basic,
physics and installation of e2e package, and application of e2e for
LHO, locking acquistion, angular fluctuation effect on the lock and
the noise in the in-lock state. Thursday is devoted for the details
of the content of e2e, Han2k package and the instlation to LHO
and Florida in order to let people get to used to it, and make sure it
works. The planning of the collaboration in the future will be discussed
on Friday.

simulation / modeling

Biplab worked on generating the noise curve using e2e. He got a code
from Kent to generate the analytic curves to validate the e2e noise
model and to compare the realistic case (e2e includes full effects)
vs the simplified noise models.

simulation code improvements

Tavio has completed the improvements of the matrix code, and
a related issues. This made the multi mode run faster almost by a factor
of 2.
After working on a few modules to understand the module structure,
he will start working on implementing thread in the simulation code.

alfi

A major overhaul was completed, expecting a much better stability.
One good feature added is a much better compatibility with the
code writting without using alfi. A through test is planned to make sure
this release is rock solid.
 

LIGO Data Analysis System

Software Systems (Maros)

 

 

The wrapperAPI was tested with UWM trivial shared object, and with
shared object that has working initSearch() and finalizeSearch()
functions. A deadlock situation was also removed from the code.

Further investigation into the bug in the dataConditionAPI revealed two
problems, one in the LDAS code and one in Linux. Fixes to the LDAS code
have been applied and tested on Solaris where the system no longer
crashes. Under Linux, there seems to be an issue with threading the disk
reads. It has been suspected that Linux's version of NFS is not mature
enough to handle the high disk thrashing caused by the threaded reads.
This issue has been worked around by use of mutexes in the threaded read
call.

Testing of the current version of LDAS continues. It has passed the
socket transmission tests, dbms tests. Most of the MDC tests (3
failures) complete. DMT testing has revealed bad XML being submitted to
the system. These requests (3 of approximately 650) were not submitted
to the metadataAPI. All other requests were inserted to the database.

Work on the new version of PERCEPS continues. The datacondAPI group will
be the first users of the new version. They will be testing it out to
flush out any remaining issues.

Mary Lei added restart, shutdown, addition and removal of APIs through
the control and monitor client interface. Startup and shutdown of the
LDAS system remains to be done. Work started on providing tape control
monitor functionality. Greg and Mary are working together to resolve
some issues.

Hardware Systems (Anderson)

 

 
 
 

All of the LIGO related HPSS accounts have been reactivated in the upgraded
CACR HPSS system, and the class of service with the current LIGO archive
holdings is being repacked to free up additional tape storage space.

13 out of the 16 new PIII/933MHz/512MB nodes in the LDAS Beowulf cluster at
Caltech are now operational.

All of the Millikan 6th floor LDAS related computers with general computing
connections have been moved to a new switch (FORE 2810), and the long
term network problems with the remaining 6th floor office computer
connections has been fully diagnosed and mostly mitigated by upgrading
the other 2 GC 6th floor network switches (FORE 3810's).

Work continues on benchmarking the DotHill RAID system.

The latest Solaris 8 maintenance update has been applied to all of the
LHO LDAS Sun computers.

Lazzarini and Anderson are working on a revised procurement breakdown
for submittal to NSF.

General Computing

MIT:
Daniel S. has setup the SUN 450 with the following:
- diagnostics test tool: type "dtt"
   The setup is similar to the one on fortress
- data monitoring tool: type "dmt"
   This will bring up the interactive root environment.
- data viewer: type "dv"
   (not very useful at this moment - needs to be redirected to files.)
- guild: LDAS database access: type "guild"
These packages are available from any SUN machine.

Livingston:
(Nothing to report)

Hanford:

- Dave B., Peter S. and Larry W. worked on getting a couple of problems
resolved
with a machine that had been blocked by CIT. Caltech blocked the machine
because
of suspicious activity coming from the unit. After discovering what was
causing
the activity CIT accepted the reasons removed the block.

CIT:
(Sam)
-Working on a new NT box for the DCC.
-Having problems with contacting Dell, they keep ignoring our calls, Gina will
work
the problem.

(Suresh)
-Installed a HP LaserJet 5000N printer in second floor west bridge
replacing
old HP Laserjet 4mv with the same name (hp2mv, hp2mvb). The duplexer unit
has
not been installed on it.
-Upgraded system firmware in two Fore 3810 workgroup switches in Millikan
6th
floor to version 5.2.2 from 4.3.0. Ports are enabled for full-duplex
auto-negotiation mode. This has resolved some of the issues that Stuart had
faced earlier. Will be upgrading the other 3810's used on the LIGO net.

(Lisa)
- found a work around to upgrading the OS on Luna.  What Rolf and Hongyu
really
needed was a box on the 113 network (cdssol11).  We used one of the new
Ultra
10's that Rolf got for development.  It still needs some software installed
on
it.
- Rolf needs an updated SparcWorks compiler.  One is installed on cdssol10.
I'm
running patches to get the OS and the compiler up to date.
- Set up an external HP CD-R on graffias.  I am compiling BurnIT software
for it
as I write.  This will help alleviate a lot of problems that I have getting
good
CDs of UNIX patches and installers.  The windows CD-R software always
truncates
the names which often causes the installers to be unhappy.  I have also had
problems with the checksums.
- I am working on getting Luna to be a functioning gateway.  This will make
it
easier to work with the workstations on the 113 network because I would be
able
to download patches and stuff directly to the box.
- Am continuing my education in Backup software.  I have Sun's Solstice
Backup
installed on a server and a client, but have yet to get a successful backup
done
with it.  It has an extremely non-intuitve user interface.
- I have been futzing with multi-media on Solaris.  This includes
installing
RealPlayer7.  I have not had much luck converting video formats, but I'm
just
playing with this a little bit here and there
- Restored files off of backup for a couple of people.
- The usual round of user problems on the PCs.

(Larry)
-Fixed a number of PC issues. The big news this week on the PC front is the
big
hit we have taken on viruses. So far no machines have been damaged and the
virusscan software has been doing its job. In the process of replacing a
number
of PC's and getting a couple of laptops setup to be used for travel.
-Installed a number of pieces of equipment. Working on the digital
camera's. One
for videos and a new one for stills. The new one for still pictures should
be
available for checkout by the end of next week.
-As usual worked a number of procurement issues. P-card reconciliation took
more
time than usual because of travel and a number of vendors not getting
invoices
sent in a timely manner.
-Working on reconfiguration of the automount maps. There will be a couple
of new
areas. One for LIGO developed tools (2-4GB of space) and another to be used
as a
scratch area (150-200GB of space) for data analysis and testing of
programs.

(Barbara)
- Began efforts to convert the DCC to Office 2000.  Converted the database
files and have begun testing the forms.
- Resumed work on the Resource database.  I need input about the LIGO
roster in order to proceed much further.
- Prepared web page for "first lock" announcement.  Sized photos, set up
the web pages, and set up the video on the media server.
- Reworked the home page to be smaller and have Roster link at the top.
