Quality/Safety (Tyler)

LIGO Hanford Observatory (LHO) and Interferometer Operations (Raab)

Summary of Commissioning Activities at LIGO Hanford Observatory  (compiled by M. Landry)

Major work this week has been on the 4K laser, as it is swapped out for another
unit (the Livingston spare), and the PSL table was reconfigured.

We had trouble with an inadvertent partial vent in the vertex, resulting in a spike
up to 9e-6torr.  While repositioning plumbing associated with a roughing pump,
a small amount of air was introduced into the vertex (vacuum seals may have
been compromised by pump hardware placed after meatlocker installation) .
Beam tube gate valves autoclosed, and later the 2K and 4K vertices were manually
isolated.  Once vertex pressures returned to standard operating points (~hours), gate
valves were reopened.  The port is blanked off and will not be worked on until the next
scheduled vent in ~June.  Plots are available in the elog, and a DCC document
will be submitted in the coming days, describing the event and future safeguards.

4K IFO
More sophistication was built into the 4k ASC system, as off-diagonal elements
were employed in the QPDs, and a new un-OPLEV filter bank was added.
The IFO was offline for the majority of the week due to the PSL swap.  The
laser team noted today that 70% transmission had been achieved in the PMC,
elogs forthcoming.

2K IFO
We chased alignment drifts for much of the week optics (examples here, and here),
often flying blind without trends or test points.  Suspicion has been cast on the input
pointing servo but drifts are evident when it is off.  The 4K is offline so we don't have
a second machine to compare.  Recall (Mar 11 weekly) we replaced pulsed heating
in the LVEA for staged heating, to mitigate 60Hz sidebands in ASQ;  temp control
was another suspect but LVEA trends do not bear this hypothesis out.

A lens was swapped out on the 2k output port ISCT10, to reduce the beamspot
size on the WFS1 photodiode.

DAQ
The state of the DAQ at the outset of the week, after major upgrades, is elogged here.

Detector/Technical Support (Coyne)

40 Meter Interferometer (Weinstein)

• Commissioning (Miyakawa, Vass, Ward, Kawamura): With the PSL problems under control (sort-of), Osamu and Rob re-established the Fabry-Perot Michelson interferometer (with misaligned PRM and SRM) and are re-measuring the noise spectrum. They are commissioning the new POB beamline. Rob is increasing the gain on the SP RFPD . Shihori is aligning and commissioning all 12 QPDs on the output beamlines. We are making plans to complete our LSC and Lock Acquisition system in preparation for locking the dual recycled IFO.
• PSL:
• We are currently running with our replacement PSL NPRO (SN 238), installed 3/11/04, and our old MOPA power supply. The MOPA cover is propped open about an inch to allow it to cool. As far as we can tell, no cooling water is running to the NPRO through the needle valve; it appears to be stuck. In this configuration, the laser is running stably, and the NPRO DTEC voltage is ~ 1.6 volts. If the MOPA cover is not propped open, the DTEC voltage rises to 2 volts, and the NPRO trips off.
• Steve looked at a history of the DTEC voltage for the last 800 days. About 150 days ago, it rose from 0.6 volts and hovered just below 2 volts while our old NPRO (SN 332) appeared to be dying. It crept closer to 2 v when we replaced it with NPRO SN 238, and the NPRO started tripping off. This indicates a long-standing cooling problem; we are guessing that we were flowing water cooling to the NPRO till the needle valve jammed 150 days ago, and have only now noticed it.
• We don't have a heat sink on the new NPRO; we have ordered and will install one. Apparently, the sites all have heat sinks on their NPRO, and either have holes punched in their MOPA cover, or have the MOPA cover propped open. We have also ordered and will install a replacement water valve for the NPRO. We are in communication with Lightwave, but the rep there doesn't think that our problem is due to cooling...!
• Intensity fluctuations out of the MOPA are 10 times larger with the new NPRO. We need to optimize the alignment from NPRO to power amplifier, to maximize power and minimize intensity fluctuations. And, we need to finish commissioning of the ISS!
• The HV on the frequency reference cavity ion pump has had no failures ever since the 24 v power cable to the ion pump HV was replaced.
• We intend to adjust the PSL slow loop temperature change in the EPICS state code.
• Optical sensing (Kawazoe, Sakata):
• Shihori is working with Bob to wire up last EOS, in the AP1 beamline.
• Rob noticed that the trigger PD for the EOS in the SP beamline was burned out; we have ordered a replacement.
• Fumiko recentered the ITMY oplev. She is writing up her studies of oplev noise. She will move on to commission the oplev servos, next.
• Electronics (B. Abbott, Heefner, Taylor, Mageswaran):
• Jay has begun generating a block diagram and requirements for the LSC as it relates to signal recycling. There will be 11 LSC RFPDs feeding I&Q demod boards; a 22x8 input matrix; and an 8x8 output matrix (including a path from CM -> MC).
• Jay and Ben are ordering parts for more high frequency RFPDs and I&Q demod boards and more IFR RF generators.
• Ben will start work on the design of high frequency (low power) RFPD boards, for double demodulation.
• Bob is running heliac cables to all the high frequency RFPDs on the optical tables.
• Ben is getting two more QPDs; one for installation on the new PO beamline, and a spare.
• We plan to do a careful search for 60 Hz pickup in our LSC crate, which is anomalously large.
• Mohana and Shihori continue to work on setting alarm limits on all EPICS channels in the EPICS alarm handler.
• Jay and/or Mohana will implement EPICS code to automatically close the mechanical shutters in the event of a vacuum transition.
• Ben continues to check out some varying monitoring readout of a couple (at least) of PSL channels (PMC transmitted DCPD and FSS transmitted DCPD) and believes it is due to a bad 3123 ADC.
• Undergrad Ben Olson is measuring the transfer functions for the STACIS isolators. He has measured the three at ETMY; two work well, providing 22 dB of attenuation at 10 Hz; one is oscillating. He will learn how to adjust the gains on the loops. The STACIS controllers that are supposed to communicate with our EPICS system have many problems...
• Digital suspension controllers (Sakata, B. Abbott, Heefner):
• Shihori has completed her writeup of the DSC input matrix diagonalization procedure and results and is submitting it to the DCC.
• She is now preparing to diagonalize the input matrix of the last two suspensions (PRM and SRM) and is preparing the procedure for diagonalizing the output matrices.
• Dual-recycling lock acquisition (Kawamura, Miyakawa):
• Seiji and Osamu continue to use Finesse to explore how the signals for the short DOFs (PRC, SRC, MICH) change during lock acquisition, in order to develop an efficient lock acquisition procedure. They are making good progress, and are optimistic. Seiji thinks that dither-locking MICH (l-) will work well, allowing us to aquire lock in the other two short degrees of freedom (PRC l+ and SRC ls) more robustly. Osamu is gearing up to test this.
• Safety (all): A follow-up safety audit was held last Monday March 29. All action items were addressed and closed. A 40m lab safety document is nearing completion. Many thanks to the safety audit team for their careful inspection and advice!
• South Annex Bake Ovens (Taylor):
• Bob is wiring up the temperature controller for new oven C.
• Bob did some bake jobs for Larry Jones' galling tests.

Bob is building 40 or 50 OSEM diode boards for Janeen and for the 40m.

LASTI (Ottaway)

LASTI Weekly Report (Allen,MacInnes,Mason,Ottaway,Ruet,Sarin)
 

Pradeep worked on characterizing the noise from Position Sensors
and Geophones and readout electronics in the LASTI HEPI setup, in
preparation for doing the same at the LLO setup starting next week.
 

Rich and Laurent have analyzed the BSC platform position vs spring tension
data and posted it on the LASTI ilog (3/31/04).
 

The BSC now has fluid running though all of the actuators, it only need
some cables in order to start running it again.
 

Myron and Ken have been finalizing the components for the vacuum
compatible geophones that will be sent to Livingston.
 

Dave measured the power saturation properties of the Lightwave 10 Watt
laser to compare with his model.
 

The LASTI vacuum system has been sealed and is now under vacuum (~1E-5
torr as of thursday morning). As this system has been up at air for nearly
a year it will take an appreciable amount of time get the water out that
has been aborbed in the viton.
 

Data Analysis and Computing (Lazzarini)

Simulation and Modeling (Bhawal)
Weekly Physics Meeting
-------------------------
Luca from LHO described current status of interferometers and current
issues related to Wave Front Sensors. The problem related to extracting
input mirrors' differential alignment signals was discussed. Matt
described his work on LinLIGO. Virginio talked about improvements in the
code for Violin modes. Biplab from LHO described phase camera that Joe
Betwiezer has set up at LHO and related problems on FFT modeling of
lensing and propagation effects.
 

More e2e examples
-------------------------
(Hiro) A few interests are expressed from overseas, one from Australia
 (Mark Barton), one from UK (Sabina H. Huttner), for use of e2e to
study the
 high finesse Fabry-Perot locking and the effect of radiation pressure
in
 Mode-cleaner.
 Two new example modules are being written so that they can start from a
 working model, instead of starting from scratch, which may be tough.
 

From LHO
-------------------
(Biplab)
 Phasemap: Received various parameters for the phase camera setup
           from Joe Betzwiezer and interacted with him about the set up
           and his data and phasemaps he captured so far.
           Introduced lens phasemap in Matlab interface for FFT but
           faced the problem of reduction in the number of pixel for
           a focussed beam.
      WFS: Interacted with Luca on FFT results and current problems of
           extracting differential Input mirror (DITM) misalignments.
           Generated signals for WFS 2a and 2b for excitation of common
           and differential ITM misalignments respectively under various
           heated conditions and calculated demodulation angles.
 

Dual Recycling Michelson Cavity
------------------------------------
(Hiro) A document, written using Mathematica, is being revised, and the
matlab
 code is cleaned up so that it is easier to define the configuration and
 running condition.
 One scenario after this is completed is that Biplab writes an e2e
 primitive and Hiro develops the formula with modal model included.
 LAL/Orsay group is interested in participating in the model
development.
 

LinLIGO
------------
(Matt) Worked on integrating sophisticated noise plotting into the
existing
  LinLIGO transfer function model.
 

FFT runs with all phase maps
-------------------------------
Xiao and Hiro have started to study the effect of the phase map on
 sidebands.
 Now with the thermal compensation working well, it is interesting to
know
 the effects of actual phase maps on various aspects.
 Last year, a SURF student, Raghu of SLU, developed a code to convert
 the measured phase map data for use in the FFT program.
 Raghu used it and placed the phase maps in the FP arms to find that the
 performance degradation is not larger. This was mainly focused on the
 Carrier. Also, the existence of the thermal effect was not taken into
 account.
 Xiao is using this software to convert more phase maps and running the
 FFT program with the thermal effect taken into account.
 There is not all data available, but this study will give
semi-quantitative
 results if the surface aberration can have observable effects on the
 performance.
 More sophisticated study will follow if this study indicates positive
 results.
 

Code development and maintenance
----------------------------------
Preparation for new e2e package release:
 Hiro and Melody are working together toward the release of the next e2e
 package, 2.0.0.
 The big thing is the dynamic linking at run time which makes e2e much
 more flexible.
 Also an effort is devoted to make the installation cleaner and robust.
 

(Melody) Modeler:
 Resolved some building and threading issues with a 64 bit Linux system.
 

 Committed FUNC_X changes into CVS and resolving some build issues.
 Worked on some documentation for the release of FUNC_X.
 

(Ed Maros) Added option to build e2e without generating documentation
           (--disable-documentation).
Alfi
-----------
(Melody) Working on using the client system's default editor to edit the
 primitive settings.
 

LIGO Data Analysis System
 

Software Systems (Blackburn)
 

Modified the frameAPI and the createRDS user command such that it
no longer uses a resource variable to determine whether or not to
perform checksums on input frame data. This functionality has now
been migrated into the user command as a flag with a default to
not checksum.
Added a new flag to user commands that read input data from frame
data to perform a sanity check on the start time of data inside a
frame against the start time of the frame filename. Performance
tests are currently being performed to determine the appropriate
default for this flag.
Work continues on TCL/Globus callbacks needed to adopt the same
paradigm as the PyGlobus package. Discovered that a separate
package was needed to suppliment TCL with thread support. This
TCL thread extension library has been added to the tclglobus
development server and development is now underway to utilize
this package in the callback solution.
Proposed an upgrade to the automake 1.8.3, and libtool 1.5.2
packages to the DASWG. No comments have been received from that
group on whether or not this is a recommended change for all
the different projects.
Rebuild all CC applications on tandem-ii environment. Discovered
an issue with emacs with this newer gcc compiler. Will be doing
further investigations on this problem prior to recompiling all
the CC applications on the LDAS-DEV system.
Made very good progress on open problem reports this week. Worked
on 15 problem reports this week, closing out 11 of these, all
under software.
 

Completed the system level test suite and posted the results.
 

Ran database performance benchmarks to compare speed of DB2 8.1
against the currently supported DB2 7.2 in preparation for the
upgrade of LDAS to DB2 8.1.
 

Hardware Systems (Anderson)
Caltech
-------
(Dan Kozak)
* Did T3 firmware (pSOS and disk) upgrades to all T3s at LLO.
* Continued emptying HPSS of LIGO data.  Have had to fix HPSS
  a number of times.  Am also saving md5sums for data in
  SAM-QFS after comparing to HPSS md5sums.
 

(Hari Pulapaka)
* Working on setting up LDR Datafindserver on ldas-gridmon.
* Added mounts for users home directories on ldas-grid.
* Working on adding new documentation for job submission on
  ldas-grid.
* Added a new metric to ganglia with output similar to iostat.
* Working with Keith and Igor by giving inputs and generally
  helping out with installing grid-related software.
 

(Al Wilson)
* Testing ldas-pcdev1 - Still having problems with this machine.
  Passes memtest. But fails burn test, and to stay running the
  OS for overnight. The last test is to load the OS and burntest
  again. All complaints have been reseated.
* Test-gridmon - System has been put online. When the grid
  machine arrives (new MB) the grid system on the test system
  will be setup and ready to go.
* BB is still giving false possessives. Datacache1 for some
  reason is still sending messages regarding disk scans. Will
  perform a reload of the BB program to see if this helps.
 

(Stuart Anderson)
* Removed the SRL sub-net from the 6th floor of Millikan.
* Worked on data distribution script to interleave data
  files from the central archive to the LDAS-CIT cluster
  internal node disk space.
* Installed Fedora Core 2 Test 2 release on test IDE-RAID
  server. This worked much better than the Test 1 release
  but still needs work before it can be used. Currently,
  the keyboard, mouse and RAID units do not fully work.
* Switched ftp mirroring tools from an old unsupported
  program named fmirror to the newer actively maintained
  and fuller-featured lftp.
 

MIT
---
(Keith Bayer)
* Installed NIS on cluster (ypserv -d is useful).
* Continuing work setting up cluster for condor.
* Helped with setup of 10 node DMT cluster.
* Specing out GE-fiber cards for dataserver/pcraid6/pcraid7.
 

Livingston
----------
(Igor Yakushin)
* Working with Patrick Sutton on preparation of the final set
  of MDC frames for LIGO and LIGO-TAMA S2 analysis.
 

Hanford
-------
(Greg Mendell)
* In the current raw frames a File Checksum exists, but FrCheck
  fails with a Frame Checksum error.  Previously there were no
  Frame Checksums in the raw frames.  I am working with
  Ben Johnson and CDS to sort this out.  It seems that the
  files are OK, but the Frame Checksum is not being set
  correctly or should be left out of the raw frames. (The Frame
  Checksum is perhaps redundant with the File Checksum for
  files with 1 frame).
* Worked with Ben Johnson and the commissioners at LHO to
  temporarily archive and reduce data from studies performed
  last week.  The final reduced data from the studies should
  be ~30 GBs, which we can permanently archive.
* I'm also working to set up another test of how LDAS handles
  the data valid flag in the frames, and will put a PR on this
  into the LDAS gnats system if the tests indicate this is
  necessary.
 

(Ben Johnson)
* The DOE Cert for ldas-grid.ligo-wa has been requested. Just
  waiting for approval/receipt.
* Linux kernels on ldas-grid and ldas-gridmon are now at
  2.4.20-30.9smp.
* Frame files being generated by the new DAQ system have
  contained bad "frame" and "file" checksums. Greg and I are
  working with CDS to make sure that the checksums from the new
  DAQ system are valid, useful, and to the frame specification.
  CDS has already modified framebuilder code to produce useful
  file checksums.
* Used "lokkit" to configure the iptables firewall on ldas-grid.
  Now it only allows incoming ssh connections. Working with Hari
  to see what the appropriate iptables settings are for Ganglia
  on ldas-gridmon.
* Working with Vern Sandberg on writing up a short report on
  the "dataValid" problem. A preliminary draft of the dataValid
  problem report with input from Stan should be enterted into
  the E-Log at LHO on Friday April 2.
 

Data Analysis Activities (Lazzarini)
Mendell:
Mike Landry and I wrote matlab code that compares the expected results
from the StackSlide and Hough code.  We hope to report on this at the
next PULG telecon.
 

Shawhan:
 

* Gave a talk at the Pacific Coast Gravity Meeting on the status of
   LIGO searches for binary inspirals
* Finished revising inspiral veto study paper (with Nelson Christensen
   and Gaby Gonzalez), and submitted it to Classical and Quantum Gravity
   for the GWDAW-8 proceedings special issue
* Working to finish paper about a new inspiral waveform consistency test
   (work done with Evan Ochsner last summer) for the GWDAW-8 proceedings
* Modified guild to add some new functionality when retrieving frame
data.
* Added information about LIGO database tables to DASWG web pages.
 

Sutton;
I drafted and presented a talk titled "Status of LIGO" at
the 20th Pacific Coast Gravity Meeting, here at Caltech.
It was well received.
 

With Igor Yakushin I've been coordinating the simulations
which will be used to characterize the efficiency of the
S2 bursts search.  They will be based on MDC frames containing
simulated signals without noise, generated by Yakushin.  I've
also proposed this to TAMA as the mechanism for joint LIGO-TAMA
simulations.
 

Finally, I've been drafting a note for the GWDAW proceedings
on our plans for the LIGO-TAMA untriggered bursts analysis.
 

Weinstein;
- Working on Inspiral review.
- Working on modeling galactic SN sources for burst search.
 

Yakushin:
Working with Patrick Sutton on preparation of the final set of MDC
frames for LIGO and LIGO-TAMA S2 analysis.
 

General Computing (Wallace)
MIT:
(Keith)
-Ordered Solaris 9 for gc (and SB1500's)
-Arranging meeting with Tufts for June LSC
-Manufacturer testing SCSI/IDE raid array
-Found trouble on new SB1500 (automount of non-existent dir)
-Replaced backup SCSI hdd for gc filesystem (with duplicate)
-Investigated booting off of LSI SCSI card on SB1500's (works)

-Current bandwidth usage can be seen at
http://teche.ligo-la.caltech.edu/mrtg/LLO-Router/130.39.245.1_1.html
-Archived bandwidth usage can be seen at
http://teche.ligo-la.caltech.edu/mrtg/archive/ under the dated folder
for the week of interest.
-Looking into some network problems at LSU (again!) that seem to stem
from their intrusion prevention system.
-Added an additional subnet and set up IPs to the PIX firewall.  Also
added the associated firewall rules for this subnet.  This will be used
exclusively for DHCP hosts.
-Moving the software archives off of the "softwareserver" AKA
annette.ligo-la.caltech.edu and moving them to a suitable location on
the RAID server.  The applications will only be available via NFS
capable systems for now.  This means that a windows user will have to
use SCP to copy installation files for software packages.
-Reinstalled the helpdesk software that we used a while back.  All
support requests for LLO GC should come through here now.
-Ordered two new UPSs for the racks that we will be installing in the
coming weeks.
-Ordered a couple of servers for the Intellution software which will
be installed on the building controls system.
-Ordered a laptop from Dell for Bonnie to use.
-Added a "network management" subnet to the PIX.  This will make it
much easier to administer the network switches around LLO.
-Working with Solsoft on an apparent bug that I have found in their
software.  The gateway selection for one of my networks is not
persistent between saves.

- Most of this week has been spent building disk systems and installing
application software on the new license server.  I had to transfer
licenses for some software and have purchased some additional licenses
and renewed maintenance support for others.
- I'm also setting up and installing Win2k on a Dell server for a CDS
project.
- I'm preparing for Mike Pedraza's visit on Apr. 12.
- Misc. user support for; ssh tunneling problems from a home computer,
web page editing how to, questions about how Norton handles virus files
and notified Ben Johnson one of his LDAS/GC gateway computers was having
problems resolving host names and couldn't send out e-mail.
- Richard McCarthy is making arrangements to have a spare fiber pair
connected through to PNNL.  This would be used for testing the new
network connection.

-Updated the Ansys license server, with a renewed research license.
-I swapped out John Zweizig, with a more updated laptop. His old laptop
would not run on battery. It would only run on AC. I have surplus his
old
laptop and pulled the old parts that were good and added them to the
updated laptop. These laptops are out of warrantee. (This is a
motherboard
problem on the old laptop)
-Work on Barry's laptop. There were multiple software issues that I
corrected for him. I also came across a backup issue that took up a lot
of
time. This was due to a hardware error that had our backup sequence
fouled
up. Everything seems to be back on track with his laptop.
-Reloaded 2 loaner laptops that came in from travel. These laptops had
OS
errors and software issues. I have these laptops back into our loaner
pool.
-Swapped out Ed Chargois's with an updated laptop that was turned in by
one
of our users. This laptop was turned in with a hardware issue. I fixed
this
with parts from a surplus laptop.
-Ghosted the following user's workstations, Irena Petrac, Ken Mailand
and
Paul Russell.
-I received a new laptop & workstation that I am currently loading GC
software, and configuring network/security settings.
-I also had the usual onsite/phone support, which included printing,
e-mail,
software, and some networking issues.

- On Sunday I put in a new primary mailserver.  The swap went very
well.  There
were a couple of small glitches with the mailman mailing lists due to a
version
change with python.  As part of the upgrade, I now have CanIt running
on acrux.
I am in the process of training the spam filters and have set up a
mailbox for
people to forward their spam to.  It turns out that some of the
forwarded spam
is being caught in the spam trap.  It's interesting that it didn't get
caught
the first time.  There is a bug fix version of the spam filters that was
released yesterday that might fix this problem.
For those corresponding with international groups you need to get the
addresses
put on a white list. The spam trap has a tendency to capture
non-English e-mail
and having people on a white list will cut down on the false positives.
Avoiding the use of html is also a plus. The e-mail filters prefer
plain text.
- As part of the switch to the new mailserver, I needed to make changes
to
sadal, the mailman server.  This resulted in a couple of glitches for
the
calendars that should now be resolved.
- Went to the ITS monthly security discussion.  That included an
interesting
presentation from someone at IPAC who went to the RSA security
conference.
Individual user passwords are still the number biggest problem in
securing a
network.
- Mail Statistics from 3/28 - 3/31
Total Messages Accepted: 10969
Total Spam Rejected: 4427
Total Viruses Rejected: 777
 

(Veronica)
- LIGO website: Installed the March newsletter. Prepared high-resolution
LIGO images for a publication by British Science Council. Updated pages
throughout the website. Updated the roster database.
Provided assistance to Donna on webpage setting. Addressed an issue with
maillists.
- LSC website: Discussed with Irena and Linda the logistics and workflow
of the MOU submission. We need to meet with all interested parties to go
through the process again before we can start working on the makeover of
the automated submittal system.
Posted late-arrival presentations from the last meeting.
- CaJAGWR website: Assisted Paula Lonergan in setup for videotaping of a
talk. I need to get the videotape from her and compress the footage for
streaming. Posted updates to the website and provided user support.

-This has been an interesting time as far as procurements go. I spent a
great
deal of time with CISCO trying to get things sorted out on their
contract.
Someone on their end just loaded a number of items on to our contract
because
the Caltech name was associated with the other equipment. It is getting
sorted
out but there is still some work to do.
Received a couple of SUN and Dell boxes.
Worked on a couple of orders for other groups.
-Continue working on the computer room expansion. PMA is now having the
power
usage from existing supplies to see if they can find enough power to
put in the
room without running a new source line.
I have started setting up the racks and populating one with test
equipment.
-We did some more testing with the WEBcams and have found that they do
work well
in a presentation type situation. Still working on getting some zoom
lenses for
the units.
Also, spent some time looking for better webcams. The industry is always
changing.
-Working a some disk cleanup. Generating a list of old accounts that we
will
pass around before removing the accounts and associated files.
-Assisted a number of users with different e-mail issues. So far they
all turned
out to be a bad configuration on the local computer or a typo on the
users part.
-No new news from ESnet on the h/w swap.
-Assisted a number of people with different web related issues. Most
just
needing to have their pages testes.
-Assisted DCC with a couple of document issues.
-The regular user support but was surprised that I did not have to
restore any
files for anyone this week.
