The following change requests have been submitted:
 

From: Cindy Akutagawa <cindy@ligo.caltech.edu>

• Various personnel/payroll /HR related work.

Quality/Safety (Tyler)

No report this week.

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

No report this week.

LIGO Livingston Observatory (LLO) and Interferometer Operations (Coles)

HEPI: This week's main goals have been to fit the HEPI actuator up into the boot that was made for the MEPI design. Final efforts have been made towards the mate of the hydraulic actuator to the boot. Concerns of L4C sensor location still concern me, as well as Jonathan Kern. Hopefully, this will be resolved by tomorrow. I spoke with Ken Mason late last night and we discussed several possible solutions for the placement of the L4C sensor. Once I finish the mounting of the aforementioned, I can once more proceed with the plumbing all of the actuators together (on each BSC assembly). During some of my free time I have been assembling the HAMS and BSC's with the changes made by EPI into one large assembly (of the entire LIGO) with the intention that other groups, i.e. suspension, optics, et al will be able to benefit from the digital model. This is an ongoing effort and is done mostly on weekends, so when I finish it, I will advertise this so that it can be utilized. The pre-isolator machined springs have been the Electroless Nickel Plating of Louisiana (ENP) and have been promised for tomorrow (Friday the 23rd). I delivered a shipping box designed especially for the springs and they have conformed that the springs will be ready midday. The fabrication for the HEPI units continues. The Actuator plates have been delivered and we are picking up vendor concerns as redlines into the drawings so that the drawing package stays up to date. The bellows have still not arrived on site yet but are expecting them any day. (Marcel Hammond)

First batch of parts for the actuator was received from P&N Monday. The parts comprising the actuator plate and resistor assembly were to spec, and were received carefully wrapped and in first class condition. An Actuator Plate, Diaphragm and Diaphragm Restraint set have been sent to Solar Atmospheres in Souderton, PA for vacuum brazing of a first article. HYSPAN shipped the bellows on Aug 15. (Jonathan Kern)

GC: Attended the Usenix conference in San Francisco and made some valuable contacts. I learned of a software product for configuring PIX firewalls (among others) that looked very useful. I will be arranging a web demo with them to further evaluate the product. I think this will be very useful for the project. LDAS: Set up a vpn tunnel between LLO and CIT last week. I will be doing some further testing once Stuart and I can coordinate some tests. (ShannonRoddy)

Preparation for S1: We have been able to easily lock the interferometer in a low noise state and maintain it in that state for hours during the night. During the day, the seismic noise continues to worsen. Logging activity is approaching the vertex area, creating some of the highest BLRMS 1-3 Hz readings we've seen on a continuous basis - around 100 counts and rising daily. Logging activity is about one half mile distant at present but will approach the property line around the LVEA over the next 2-3 weeks. We have been preparing the general area within the LVEA and VEAs to remove sources of electronic noise and mechanical vibration that can be turned off or removed during the run, such as lights in the VEAs, dust monitors, annulus turbo pumps, etc. Signs and chains directing and controlling traffic flow around the site will set up Friday morning. The auto-locker script which acquires interferometer lock, turns on the common mode, increases the optical power, and recovers if lock is broken, has been tested repeatedly this week and seems to work very well.

LSU Chancellor Mark Emmert will visit LLO on September 5. Louisiana Secretary of Economic Development Don Hutchison will make a presentation to the Southern Governors Conference this Saturday that will include mention of LIGO as a contributor to the technical resources of the southeastern Louisiana region.

Detector/Technical Support (Coyne)

40 Meter Interferometer (Weinstein)

• Alan, Dennis, and Osamu are at the LSC meeting. Steve is on vacation.
• The 40m Technical Advisory Committee met on Wednesday morning for an hour. Dennis presented the status report, with emphasis on our mode cleaner. There was some discussion of Marcus' results on AdvLIGO wavefront sensing.
• SURF students Ilya, Marcus, David, and Aya gave stellar talks at Tuesday's SURF seminar day. It's the last week for all but Dave.
• Optical sensing (Smith):
• AP2, OMC_R, SPS, BS PO, ITM PO ISC Optical Trains: The spot size matching lenses in the AP2, OMC_R, BS PO, and ITM PO ISC table optical trains were determined, and components were moved to establish the appropriate beam spot sizes throughout the optical train. The generalized equations for calculating the Guoy phases on all the PO paths were set up. The actual values and positions of the Guoy telescope lenses for the OMC_R, SPS, BS PO, and ITM PO will be determined after the Guoy phases have been established The integrated layout drawing was updated to reflect the changes.
• IO Diagnostics: A technical note is being written to describe the design and calibration procedure for the IO position sensing and angle sensing optical systems.
• Optics Parts List: Purchase orders were placed for most of the opto-mechanical parts for the AP1, AP2, ITM PO, BS PO, ETM PO, and SPS ISC beams  and sensing table optical trains. Parts were received from Thorlabs and Watec. Missing lenses for the IO diagnostics optical train were received.
• CDS (from Ben):
• I have been helping Illya and Dave with some technical aspects of their SURF projects.
• Bob and I have run coaxial video cable and power for the cameras to the auxillary rack.
• I ordered connectors that will allow me to test and install the WFS whitening interface boards.
• I tried to find the 500KHz noise on the PSL light that Peter Fritchel talked about notching out of the ISS DC photodiode. As it stands, I cannot find it at the 40m. I will try with the laser in Lauritzen, to see if it is there.
• (From Bob):
• Wiring and OSEMs have the big players this week, I have completed and tested 10 long OSEM boards and 3 short boards. The short OSEM board seem to be more of a problem. I think I just had a few bad diodes that have been giving me problems but I have reworked those boards and am now ready to test them today.
• Ben and I have put in six of the camera / power cables and more will likely go in today.
• I have built the rheostat panel and am still waiting on the relays from Phoenix Contact.
• I have the temperature controller for oven "F" designed and in the machine shop.
• The baseline scan on oven "C" has been done and I am waiting for Steve to give me instructions on the seismic stack cables.
• Oh yes, one of the M200 Daycor RGAs is giving me problems and I have attempted to repair it but I think I will have to send it back for repair. This RGA was repaired in 1999 and was sent in by Yehuda and at that time it seem to have the same scanning problem. I will get a quote on fixing it from Ametek.

Thermal Noise Interferometer (Libbrecht)

No report this week.

LASTI (Zucker)

MEPI / LASTI
(Mason, Ottoway, Mittleman, MacInnis, Megan, Kern)

The installation of the External Pre-Isolators is proceeding very well.  We installed the last 2 of 4 EPI housings this week and the heavy lifting is completed.  The HAM is now supported on the EPI's hard stops, and the assemblies have been shimmed and leveled.  The pneumatic lifts for coarse actuation have been installed and tested.  Myron designed a clever fixture that allowed us (with considerable manhandling) to remove the old piers and install the EPIs in the very cramped area between the vessel and wall. After completing all four installations, we're pleased that the measured displacement in all three axes, at all four corners is < 0.005" and yaw < 50u-rad. Next week we will install the EPI suspension springs and load cells, and begin the task of leveling and aligning the table.  See some images of the installation at
http://emvogil-3.mit.edu/~jkern/MEPI082302/index.htm

HEPI
(Hammond, Kern)

First batch of parts for the actuator was received from P&N Monday. The parts comprising the actuator plate and resistor assembly were to spec, and were received carefully wrapped and in first class condition.  An Actuator Plate, Diaphragm and Diaphragm Restraint set have been sent to Solar Atmospheres in Souderton, PA for vacuum brazing of a first article. HYSPAN shipped the bellows on Aug 15.

Data Analysis and Computing (Lazzarini)

Simulation and Modeling (Bhawal)

Bistable locking in mode-mismatched IFO

(Biplab) The following studies were made to understand degeneracy of the recycling cavity and differences between FFT and Han2k locked states.

• Keeping arm cavity mirrors fixed at positions specified by locked lengths from FFT runs, the recycling mirror was moved at slow speed (only l+ changes)
• Repeated the same procedure but this time fixed the arm cavity mirrors at positions specified by locked states of Han2k model which are found to be different from FFT-locked positions.  It was observed that the Sideband resonance curves generated by these time-sweep procedures have two humps in it which originate from mismatches in cavities (also seen by Bill Kells in FFT studies). While FFT-locked state sits at around the crest in between these two peaks, the Han2k lock acquisition system, being more realistic, tries to approach one of these peaks. This also explains why we were getting a sudden transition in locked positions in Han2k model at a heated state characterised by refractive index of about 1.25 (in a scale of 1.45 at cold to 0.9 at final hot state).  Han2k locked position shifts from one peak to another at near this state.

(Biplab & Matt) We made some progress in understanding differences in energy conservation error (in E2E runs) between static and dynamic misalignments of mirrors in a cavity. The time-evolution of internal fields turned out to be a crucial factor and must be included in error calculation.

Code development and maintenance

(Ed Maros) Gave Biplab instructions on how to tag and build a release.

Alfi

• (Bruce) Refitting the parser with better error messaging and graceful    handling of problems involving bad formatting in an Alfi file.
• (Melody) Continuing work on the automated tester for alfi5.

Software Systems (Blackburn)

The work continued on writing a new frameCPP C++ I/O library for the version 6 frame specification.  The effort necessary to maintain backwards support was probably underestimated but the plan is still to have this ready for integration starting with LDAS early late next week.

Work also continued on adding new functionality to the frameAPI to push the bulk of a user request into a unique thread, all within the C++ layer to allow multiple CPUs to be used by the frameAPI application, while also increasing efficiency by removing some TCL layer management of data objects.

The reusable state vector data objects used by the wrapperAPI search codes was found to be broken this week. A fix is being implemented and a standard system test written up to allow us to completely test this feature in every release.

Three releases of LAL and LALwrapper have been announced this week. These are part of our ramping up for the science run. The LDAS team has found several problems in these releases and provided the LSC authors with the details of the failure modes, facilitating a timely fix and new release.

The latest release of Bwidgets has been integrated into the cmonClient. This fixes several refresh issues but has removed some color from the interface.

The ldasjobs package has been updated to automatically handle a newly discovered (post-release) bug in the managerAPI. The fix will reissue the job when the error is detected. This error is seen with the T1 line to the sites are near full utilization which results in packets piling up at the managerAPI.

Hardware Systems (Mendell for Anderson)

(Greg Mendell)

• Set up a new RAID server with 2 TBs of disk space.  This is almost complete, though some problems with network connections may be occuring, and some configuration is still needed.
• Prepared drawings for the move of the LHO LDAS equipment in the staging building to the new building.  The plan is to move at the end of September or early October, after S1 data has been backed up into HPSS and distributed.
• Prepared to archive S1 data onto tape, and injections and calibration data from Wednesday and Thursday of this week.
• Trouble-shot two crashes of the network switch.  The switch is working now; Foundry has agreed to send a backup for the chassis.

• HPSS: continued migration of small files off of 3590 tapes.

• Successfully tested SAM-QFS configuration for sites/CIT.  This involved writing data to a SAM-QFS instance which dual copied the data to tape, then exporting one of the sets of tapes (and associated metadata) and importing it into another SAM-QFS instance.  I'm continuing to fine tune this process, but it is working quite well so far.

At LSC meeting.

• experimented with sw raid on PC Raid Box (datawulf)

• Released RH7.3 to the rsync server
• Fixed mail problems with stand alone ldas systems.

(Mendell)

• Attended that August 2002 LSC meeting; worked with the PULG group on our analysis; chaired the PULG individual session.

• Helped Anand Sengupta (Dhurandhar visiting student) to read LIGO data into his prototype search code running within the standalone wrapper. This code implements a time-decimated hierarchical and mass templated search for iinspiraling binaries.

MIT:
(Keith)

• Finishing off the MU7 update
• All solaris machines now running patched versions of openssl / openssh
• Troubleshooting wireless difficulty with new IBM laptop
• Dedicating lancelot to DMT / LDAS work (off of gc network)
• Purchased PC + software for CAD work (Jamie)
• Finally purchased PC for D-space work (Peter/Richard)

• Attended the Usenix conference in San Francisco and made some valuable contacts.  I learned of a software product for configuring PIX firewalls (among others) that looked very useful.  I will be arranging a web demo with them to further evaluate the product.  I think this will be very useful for the project.

• It's been a very busy time getting the network into the new building and getting it to work in time for the LSC meeting.  By late Sunday night the wireless network in the auditorium worked and most of the ethernet jacks at each of the auditorium seats worked.
• For the LSC meeting I setup five breakout rooms with computers, projectors and overhead projectors and setup a computer and printer for admin in the reception area of the new building.
• Larry worked on the VRVS video conferencing computer and was able to get periods of transmission with fairly good video and audio.
• Helped many people with network and file transfer problems during the LSC meeting.
• Monday night esnet took our network down to upgrade the operating system on their cisco router in hope of eliminating the errors we've had on our original bandwidth upgrade.  The IOS upgrade made no difference.
• Meanwhile during the network down time it was decided to remove a switch from between our cisco router and our ATM 3810 hub.  It was late at night after a long stressful day and no one noticed that by removing the switch the DHCP server which was plugged into the switch now had no network.  The lack of a DHCP network was very noticeable on Tuesday morning.  Adding to the chaos, workers pulling fiber for LDAS into the GC server room knocked the keyboard cables which went to the file server and e-mail server out of the KVM switch, which caused the servers to freeze. Due to "too many cooks in the kitchen" more damage was done, files were deleted that didn't need to be deleted and then had to be recreated later and it took three times longer to repair the problem than it should have taken.
• PNNL and esnet have found that their cisco hardware is not able to provide the 10 megabits upgrade we had wanted.  PNNL was able to put a switch between the esnet cisco router and the ligo connection which has brought us back to T1 bandwidth and has eliminated the errors on the cisco routers.  The next step is to explore what hardware upgrades need to be made to improve the bandwidth.
• Created five new user accounts and changed the passwords on two others for people who had forgotten their passwords.
• Helped some remote users with account and disk problems on the DMT computers.  Shared the license server Matlab files with the DMT machines for software development.
• Worked on hardware problems on Otto's computer and finally setup a temporary computer for him until I can get his computer fixed.

• Helped with with a number of things for the LSC setup. Mostly, cabling and cleanup. Also, helped a number of attendees with their computer setups. Assisted Linda Turner with her setup and helped her get things going to get the presentation files transferred to Caltech. Also, wound up donating my laptop for presentation usage. Richard, Christine, Dave, Otto, Terry and any others really got things together for the LSC meeting.
• Met with Albert and John McCoy (from PNNL) concerning the network upgrade. John is working setting up a meeting with the ESnet and a few others to start discussing the hardware options needed for the upgrade. Albert will be contacting ESnet concerning related issues.
• Continued testing the network connections and passed the information to Cullen who has really been doing a good job working out the performance issues. Since, Cullen has resolved a few issues today the network is now running well above T1 speeds.
• Spent a deal of time with the VRVS system. The Hanford machine would lock up on a regular basis. No reason discovered. Also, tested the direct audio feed from the microphone system, so far it is not working very well, more testing and debugging needs to be done. For some reason the audio would have transmission breaks on a regular basis. We did have good audio and video for short periods of time. We will be working on resolving the issues to get better performance on the VRVS system and looking into some alternatives.

• We were having a few database problems on Anteres but as of now everything seem's to be running okay. I have transferred this server back into the server room.
• Loaded a 2000 server to replace Amaldi that is currently running on NTSRV4.0. I have more testing and to do before I swap out
• servers. This is currently hosting the ELBA website.
• Wendy and I have upgraded multiple PC's that were running win98 and now have them upgraded to 2000 Professional. This has been going pretty good with minimal problems. I have not heard any complaints from users other than a few software adjustments.
• Performed a-lot of user support that included software, virus, hardware and printing problems.  It looks like we got a handle on things as of this morning.

• Loaded and ghosted more machines with win2k, including one that we loaded from the Ghost image.
• Worked on tape restoration a bit.

• Rewired 3rd floor network closet with Lisa and Christian
• Helped move some equipment in subbasement

• LSC website: as the transparencies from the LSC meeting keep coming, I am posting them.  Posted a few last-minute updates to the meeting webpage.  Updated MOUs webpage.
• LIGO website: posted several updates to the Internal Bulletin Board.  Tracked down a problem in the DCC document search; the problem was related to an incorrect drive mapping between internal and public components of the DCC, and is now fixed. Together with Lisa and Mike, looked into an unrelated problem with a document not being linked to its pdf file.  Attended a presentation on Adobe digital video editing tool collection. Posted the new webpage 'Commonly Used Email Archives.'   Posted July newsletter.   Started working on webpages for the Aspen'03 Winter conference.  Per Lisa's request generated a few banner graphics.  Tracked down a cause for a log file error for LIGO homepage.  Working on the updates for the 'Experimental GW Groups' webpage.

• Worked on some web server issues.
• Spent most of the week working implementation of a new archiver for the mailman mailing lists. It is mime aware and includes a search engine. The new archiver is ready to be put into production as soon as I can get off-hours down time on the system.
• Recabled the 3d floor Bridge network closet with the help of Mick and Christian.

• Went through a number of procurement issues.
• Worked through a few application installations. Went over the mailman upgrade with Lisa. It is looking pretty good.

Advanced LIGO Suspensions
(From: Janeen Romie <romie_j@ligo.caltech.edu>)

Superior Jig is having problems producing the larger of the two mode cleaner blades. They started work on these quite late - on the original delivery date to be exact. Gina Salone is supporting me in working with them. They have delivered four small blades. Lobart is due to deliver their blades on Aug. 29th. We will get drawings of the RM blades to Gina as soon as possible to start that procurement.

Mike in CES says that he can most likely meet our Sept 15th delivery date for the second MC structure. We plan to get the second suspension's parts cleaned and baked while we're still working with the first suspension. This should facilitate a mid- October delivery of a clean MC prototype to LASTI.

Currently, I'm working on the magnet gluing fixture for the MC suspension. This fixture can also be used, with a bit of modification, for one of the Gin Gin suspensions.

Prototype Mode Cleaner Suspension

Mike Plissi is visiting us for one month from the University of Glasgow, he can be contacted by email on m.plissi@pgysics.gla.ac.uk or by phone on x ???
Janeen and I have been receiving parts from the various Campus workshops as well as piece parts from outside shops. Mike and I have been going through and sorting all of the parts in the Synchrotron Laboratory and I believe he is happy with most of the parts. A couple of extra parts have had to be machined and one or two are back in machine shop getting re-machined but this was expected and both Ric and Mike in the two main machine shops had set aside some time for this.  Mike and I have started assembly of the wire jigs and some aspects of the upper mass.

SURF

John Veitch and Dan Mason are coming to the end of their surfing time and both hope to have a report written before the weekend.

SOFTWARE

1) After a long struggle I believe we have persuaded SolidWorks to remove the restrictions imposed in their recent service pack They have just released a new service pack 4.1 as follows:

SolidWorks 2001Plus Service Pack 4.1
SolidWorks 2001Plus SP4.0 included a change that prevented commercial or research versions of SolidWorks software from opening files generated using Education or Student versions of SolidWorks software.  SolidWorks 2001Plus SP4.1 removes the restriction that was added in Service Pack 4.0 of opening files created in Educational and Student versions in the commercial or research versions. Please note that this is the only change that went into Service Pack 4.1.  SolidWorks Corporation maintains the position that the Education or Student generated files are for instructional use and not intended to be used with commercial software.

Who should upgrade to Service Pack 4.1
Customers should upgrade to SolidWorks 2001Plus SP4.1 only if they intend to use Educational and Student versions of software in the
commercial or research versions.

I have updated to service pack 4.1 and have had no problems opening educational files.

2) Tony Jones, from Rutherford Laboratory, and I have been exchanging Pro Engineer and SolidWorks files in order to investigate compatibility.  So far I have been able to open .igs files with SOLIDWORKS and as I have FeatureWorks I can recognise the various features like the hole etc., but for some reason it does not allow me to edit the original sketch?  In contrast when I take a AutoCAD file and save it as a .sat file and then open it with SOLIDWORKS I can recognise the features and edit the original sketch.

3) Go Engineer have Marcel's information and have promised to get back to us all this week to fix up the second licence for 3D-TeamWorks. When this happens I will ask Marcel for some help with the PDM Works.

Advanced LIGO Coatings
(From: Helena Armandula <ahelena@ligo.caltech.edu>)

Received the Ta2O5 / Al2O3 coating run from Wave Precision.  Two 3" dia. x 1" thick coated parts plus an uncoated annealed substrate have been shipped to Glasgow.  One of the thin coated substrates was shipped to MIT ; the other to Syracuse University.  1" dia. coated substrates will be shipped to Stanford for absorption measurements.

Sent "Q" substrates to SMA / Lyon to be coated with doped Ta2O5 and SiO2.
