Weekly Report Highlights

Vacuum Board will meet Friday 17 September to review H2O outgassing data from SEI seats and to make a recommnedation on how to proceed.

LIGO Hanford Observatory (LHO) Operations (J. Worden)

John Worden was able to file and polish the damaged areas, and we have since confirmed that the flanges are still usable.

Load #57, consisting of two LOS structures + misc. fasteners, is currently vacuum baking and should be released on Monday 9-20-99.

Computing:

Monday night and again Wednesday night a hacker with an Italy ip address broke into the subnet.  The assault was halted early, it looks like nothing was left on our system.  Most of the rest of the week has been spent cleaning up and trying to put in measures to prevent any future break-ins.

If you have not changed your password on rainier, the LHO server, please do so.  As a result of the hacker and trying to get everyone to change their passwords, we discovered a problem with Secure Shell 2.0.  Apparently ssh 2.0 is not compatible with the nispasswd command.  We think it may be the way ssh encrypts the password.  We found that the old ssh 1.3 does work with the nispasswd.

LIGO Livingston Observatory (LLO) Operations

Optics: We have started assembling the first small optics suspension (tower and optic). This will be used for testing purposes. We made six magnet dumbbell combinations following the new fixture and procedure (cure glue at 100 C for 1 hour). We cleaned one steering mirror following the new cleaning procedure (put the optic in liquinox solution in an inner beaker and put the inner beaker in an outer beaker filled with DI water). We brought the solution temperature to 70 deg C and held for 15 min. Both surfaces passed the water test after the second time using this procedure. Jonathan Kern has devised an apparatus to measure optic thickness using a height gauge and a microscope. It works well. Using this apparatus, we measured the thickness of the steering mirror. The thicker side (on which a wire standoff will be put) has been measured to be 24.76 mm. Jordan Camp measured the field strength of the 50 magnets shipped from UF (and baked at CIT). They are grouped to Group O through Group T. The scattering of the strength within groups is less than 1.5%. The new groups are stored at the same place as the first groups (Group A through Group N). (Sany Yoshida)

Jonathan completed the alignment telescope fixture for Sany, and began work on a modified fixture to assist in wire standoff alignment. Awaiting 2 ball lead screws, as well as powdercoating of the modified straddle fixture. Corrected an oversized hole problem in an SOS for Dave Tanner.  Corrected numerous problems with several of the surplus vehicles in our carpool (another engine blew up this week, trying to get 2 running for bakeout support). (Jonathan Kern)

Beam tube bakeout: We have started to ramp down the bake of the X2 module. Expected time of this ramp is 3 days and we should be at ambient temp. by monday. At this time Rai feels we have a good bake. The Y-arm end station has been vented and is at atmospheric pressure and purged for detector installation activities.

Two of our QDP-80 pumps have failed in the last week and will have to be returned to Edwards for repair. Unfortunately, both are out of warranty and the cost will be about $6500 for each repair. (Allen Sibley)

PSL: The PSL enclosure was cleaned. Some open spots on the cement floor should be sealed to reduce the production of dust. With the HEPA filters turned on in the laser table enclosure, the particle count reads zero.The pre mode cleaner is in place and aligned. The mode matching looks good and is being checked. The PZT of the pre mode cleaner will then be characterized. After this, the pre mode cleaner can be locked with a temporary circuit and the total light output of the PSL can be measured. (Joe Kovalik)

Bake Oven: We have completed baking all BSC parts and are currently baking RGA-tree components. (Tom Evans)

Control and data acquisition system: The SOS rack (1X6) is ready for test. Rolf and Jay will be here on Tuesday to run through it.  The cables for the SOS satellite modules are run and awaiting termination.  Graphic displays for data acquisition are being updated so that they recognize the path for Livingston. Permanent CDS power is now tied into the end station racks. Power for the paging system is installed. (Rus Wooley)

Servo Test Stand--Serial cable made to communicate with Baja. Sucessfully comunicated with Baja using serial port. Baja successfully loaded epics and startup file. It can now be logged on from the net. Wrote and successfully tested a "c" program on the Baja.

Suspension Test Stand--Talked with Jay Heefner and got operations manual for Stand. He recommended that I check that the serial ports on the 162 were contected correctly. They were not. Joe and Rusyl swapped them to the correct positions. Sani and I went thru with a scope and signal generator and checked the circuits. Moving the OSEM from LL thru to Side we checked both sides of the stand and found everything is now working.

Weather Station--Problem with Web data uncovered; James Finney says Web data is now reasonable back to Sept 1st ; various fine tuning continues.  (Anthony Rizzi)

Facilities: The Louisiana Love Bug scourge continuous to plague operations in terms of maintaining cleanliness. Pest control experts maintain that only a cold snap will bring relief, as no effective spray is available to check the problem. The access road is still not available for traffic. The contractor has started to place gravel on the shoulder and estimates another week for completion. (Gerry Stapfer)

Initial Alignment (Matt Smith)

IO Testing  (Peter Fritschel)

• MC1 diagonalization completed with some success; in particular the angular motion of MC1 was significantly reduced after the diagonalization.
• Calculated value of the local damping gain which minimizes the optic's rms motion. Still to be implemented on the MC mirrors.
• Took 15 minute data run with stably locked MC using Shourov's data acquisition system. Channels measured were three axes of a seismometer, the MC length control signal (to MC3), the MC laser frequency feed back signal (to VCO), and the MC transmitted light. Data and some first-look results in ~gonzalez/HanfordSept99/ on LHO machines.
• Electro-optic shutter got working. Locked MC with higher power. Observed oscillation at 1 Hz when power got to 1 W. Found that MMT3 was not damped and was swinging at 1 Hz. Replaced satellite box (blown PD bias supply).
• PZT steering mirrors "sing" at 5 and 10 kHz. Problem found to be with PZT driver, which is now being worked by Jay and Richard.
• Internal Q's of MC mirrors drumhead mode were measured and found to be good, all were above 3e5.

• Two 21.5 MHz frequency reference cards are in the final stages of  manufacture. The frequency reference cards provide the local oscillator and phase shifter signals for the frequency stabilization servo electronics.
• Two 80 MHz VCO are in the final stages of manufacture.
• Laser SN #110 was delivered by Lightwave Electronics.

• Haisheng and Stan measured the Q's of the 28.2 kHz resonance for the three MC mirrors in situ with the following results:

MC1 7.8 x 10^5
MC2 3.7 x 10^5
MC3 1.35 x 10^6
These are better than the SOS Final Design spec.
• The aluminum brackets for the in-vacuum beam dumps are being manufactured now. The black glass and its antireflection coating has been ordered, with delivery expected in 2-3 weeks. We will coordinate the clean/bake of these with Janeen Romie at CIT.

Mechanical Design (Dan Dickrell)
Our shop has finished a few remaining parts for the IOO installation at Livingston: Holders for the 2 PZT mounts on the PSL/IOO table and vented posts for the DLC fixed in-vacuum mirror mounts. These will be shipped to LLO shortly; the posts and fork clamps will need to be put in the queue for clean/bake.

Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)

• Vendors have delayed delivering the final parts for the little beam dumps. The stands won't be here till tomorrow. The delay in the vent at LHO makes this slip acceptable. We will try to get those parts to the sites by the end of next week after cleaning and baking.
• Working with IO folks on SOS suspension issues.  Attended the meeting on SOS diagonalization on Tuesday.
• Doing more prep work for LLO suspensions. Ordered more equipment and parts.
• Submitted a design to CES for fabrication of a bracket that will work with the optics holder to hold the optics in place while they are baking.

I also prepared for trip next week to LHO by installing the new (now understood and working well) versions of gcc on the DMT machine and reorganising all the dmt software directories to be transferred to CVS. I have started a perl script to manage the running of monitors and the infrastructure processes.

Time spent debugging diagnostics test code and solve synchronization problems between different CPUs.

Physics Environmental Monitor(Matt Smith, David Shoemaker)

General

• Working on a proposal for a configuration control scheme for CDS installations at the sites. A draft document should be out in the next few days.
• Received quotes for most of remaining Commercial Off The Shelf (COTS) items necessary to complete both sites. Orders will be placed over the next few days.

• Completed the testing and calibration of 3 WFS PDs. 2 Bull's eye PDs are being tested and should be complete by 9/17.
• Construction of the X and Y arm ASC controls wiring harness is complete. The harnesses will be shipped to LHO next week.

• Two LSC One Arm Servo Amplifiers are complete and ready for test. Tests should be complete by 9/24.
• Power supplies and crates have been mounted in rack 2X1.
• System drawings for the One arm LSC controls are 95% complete. The wiring harness for rack 2X1 has been started and should be complete by 9/24.

• Chassis for the remaining SOS and LOS controllers have been ordered and should be delivered by 10/20.
• Two LOS controllers for LLO COS are being tested.
• System tests for LLO IO Suspension controls will be done by 9/24.
• We have run out of Satellite modules and are in the process of fabricating the remining modules. Fabrication has hit a snag because the vendor who engraves the boxes for us is holding them until they are paid for their last invoice. (I guess they are not impressed by Caltech's new finance system). At last word, Caltech was going to cut a check and Paul Russell was going to deliver it to the vendor and pick up the boxes.

GPS Timing System: (DAO)

PSL (Rich)

40M Lab (Rolf)

• A stuck bit was identified by John Zweizig on data coming from the ICS ADC module. The ADC module was replaced. Problem turned out to be a bent pin on the edge connector.
• Added three more 16KHz channels to the acquisition system.

• Hongyu completed the operator's manual for version 2 of the Dataviewer software. This will be distributed to the sites.
• Alex adding a new class to the Frame C++ library to improve the write performance of the system.
• Looking into alternatives for storing trend data to improve the data retrieval rates.
• PMC reflected memory modules due on loan from VMIC tomorrow. Will evaluate next week to verify they will meet performance needs (>12MByte/sec) for Hanford site.

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

• For the past two week's processing statistics, check the DCC web page.
• Continued working with Paul Kabot on identifying numerous duplicate numbers representing different hardware parts.  Several options were discussed with Paul and Mike Smith in cross-referencing any number changes.  Further discussion is planned before setting up a procedure.
• Battled with printer and software problems to empty an overloaded OUT folder of electronic document submittals.  Over 80 documents were successfully processed and placed on-line.  However, there still remains about 30 documents.  With luck, these too should be available on-line in the next couple of days.
• Met with Dennis Coyne and several others from Hanford regarding the use and processing of Process Travelers.

From: Kris Duncan <kris@ligo.caltech.edu>

• Completed and distributed the July 1999 CSSR.  The construction project is currently 95.9% complete.
• Advanced the calendars in COBRA and posted  the level of effort earned value for the R&D and Project Office accounts.
• Continued to work with WEBSTER to download August 1999 actual costs to date.  The commitment data continues to be incorrect.
• Began a replan of the four LDAS accounts in COBRA based on Albert's input.
• Received (2) Excel files that consisted of staffing plans located at the various sites (CIT, LHO, LLO and MIT) and put the information into a MS Project format.
• Continuing to review "Open Plan" schedule files and update them for task managers review for August 1999 status.

Spent a lot of time working on providing information regarding problems I had encountered with Oracle to various individuals working on correcting them.  Good news is that corrections are being made.  However, reports for August 99 for both Construction and Operations accounts should be viewed with caution since most of the corrections were not made until September.  Problems to be aware of include:

• Overstatement of encumbrances due to certain contract balances being entered twice.  This problem has been corrected in September.
• P-Card transactions for July and August are not reflected on the Oracle reports for August.  This problem has also been corrected in September.
• Travel encumbrances overstated.  This problem appears to be on-going at this point.
• Overstatement of overhead charges due to misclassifications of items from Equipment to Materials and Supplies.  Acquisitions and Payables Department has been provided with a list and are in the process of making corrections.

Downloading detailed cost and encumbrance data from WEBSTER has proven difficult since the system has not been responsive for most of the week.  Since this is the first time since the conversion from IFIS it is VERY important that everyone takes the time to really look these figures over.  Only the Task Managers can tell if these expenditures/encumbrances are against the correct account and we need to get all corrections started as quickly as possible as it may take a LONG time to get the errors corrected.  Cindy will be preparing a report for distribution and review as soon as the process of downloading all of the data can be completed.  We will need people's cooperation reviewing the data.

[Masha Barnes]

• (MB) Added getLwTOC() function to lwAPI to display content of specified LIGO_LW element in the document.
• (MB) putLwData() for lwAPI: ability to store raw data in external files for specified elements:
• got it to work;
• tested.
• (MB) Working on getLwData function for lwAPI to handle externally stored data in the elements.
• (MB) Had a meeting with Phil on generating frame ilwd files of different size for time testing.

• (JKB) Wrote Quarterly Report section for LDAS software group.
• (JKB) Held two Group Meetings to maintain the level of  awareness as to where our current transition software problems fall and how to resolve them. Learned that the C++ object sockets are currently not working and this is getting high priority. I have been working closely with Nathan to track this down and fix it. Spent a good deal of time working with rest of group on each individuals particular difficulties, training in some sense on the use of Unix development/debugging tools.

The state of the Makefile are probably of second highest priority. At this point we have pretty much fixed all the GNU GCC 2.9.5.1 issues.
• (JKB) Helped Masha track down a problem using standalone executables that link in the TCL API libraries but don't run in TCL. Described a way to use DDD with the tclsh shell. (
• JKB) Worked with the Univ. of Florida group to get them up to speed using the elastic cylinder resonance frequency and effective mass code.
• (JKB) Downloaded new C and FORTRAN compilers from Compaq for the Alpha processor but due to some auto mount issues on sadan, have not been able to install and test them yet.

• (PSE) Wrote an index file for the developer docs for LDAS to provide a single entry point for all Tcl and C++ code in all the API's.
• (PSE) Wrote documentation for the getData user command and an index page for the user command docs.
• (PSE) Began to investigate resource requirement issues of the frame and lw API's.  Each of these API's might require a large pool of physical memory to be able to run smoothly for extended periods of time.

• (XH) updated the the database web pages.
• (XH) worked on other database documentations.
• (XH) fixed some bugs related to database.

• (BK) Cloned the CDS Channel Configuration application for Livingston. Created a second database and loaded the basic channels substituting an "L" for the "H" in the channel names.  Copied all the forms and pointed them at the new database.

• (BS) Ilog system:
• User database maintenance at LLO.
• (BS) VRVS Video-Conferencing System:
• Reported to Albert on comparisons of the VRVS system with other video-conferencing systems such as CU-SeeMe, MeetingPoint, and NetMeeting.  The system which best suits LIGO needs apears to be VRVS, though the other systems also have their points.
• (BS) LDAS Code Documentation:
• Researching the Perceps tool for C++ documentation for the LDAS group.  Looking into how it has been used in the group already in order to make guidelines for auto-documentation of new C++ code written by members of the group who have not yet been using Perceps.

• (NY) Continued development of prototype data conditioning classes, including the wrapper for the power spectrum functionality, which now conforms to the specification laid out in the LIGO Data Analysis System - Numerical Algorithms Library Specification and Style Guide document.
• (NY) Found two minor problems in the compilation of the ospace libraries that might account for segmentation faults occuring in calls to the genericAPI.  Recompiled ospace for Sun and Linux platforms, recompiled genericAPI for Sun, working on Linux.
• (NY) Identified a possible casting problem in the implementation of the general lib, in the destructor of the class LdasBinary, and will look into workarounds once everything is compiling and testable.
• (NY) Began modifying tcl scripts for testing purposes in my linux and sun environments

Larry Wallace

We have received the quotes for the SUN units and the PC's. Those orders should be started today. Cable orders should be out this week also. The NTI switch box has arrived at Livingston. Tom E. is checking items out the facilitate the running of the cables at the Observatory.

General Computing

MIT:
Working on getting new PC's. Also acquiring the Exceed pkg. from Hummingbird.

Livingston:
Larry worked through some FTP issues with Alan S.. The transfer was completed but Alan will need to get some of the logistics worked out with Tom so the transfers can go a little easier.

Hanford:
(Christine P. Submitted purchase requests for more user PCs and a laptop to be used as the System Administrator's troubleshooting/testing tool.  Attended the General Computing meeting.  Albert was able to get connection to the LHO modem pool from Caltech, still have not been able to reproduce that from LHO. Larry has also been able to get on the modem pool from Caltech. Gary Sanders has agreed to help test it when he is here on 9/16. Part of the debugging problem has been that the only computers at LHO with modems are Rick Savage's and Fred Raab's laptops and Richard McCarthy's PC.  Testing can only be done when one of these computers is available for testing.

Monday night and again Wednesday night a hacker with an Italian ip address broke into the subnet.  The assault was halted early, it looks like nothing was left on our system.  Most of the rest of the week has been spent cleaning up and trying to put in measures to prevent any future break-ins.

If you have not changed your password on rainier, the LHO server, please do so.  As a result of the hacker and trying to get everyone to change their passwords, we discovered a problem with Secure Shell 2.0. Apparently ssh 2.0 is not compatible with the nispasswd command.  We think it may be the way ssh encrypts the password.  We found that the old ssh 1.3 does work with the nispasswd.

CIT:
Barbara K. set up web pages for the Celebration. Helped with queries on the Celebration database.  Made several minor changes to the tables and form.  Made miscellaneous web site changes -- added links to LIGO II site and to LIGO II documents on LSC page, removed links to Old Document Index.

Samantha B. is working on updating code written by Sean and is having some difficulty because of the lack of documentation of the code. Set up a new computer for Cindy and Akiteru Takamori. Helped Liz with a few computer issues. Discovered how to print a blank page in print job originating from PC's, now working on getting the banners to work correctly. Worked on Dale's PC in Wilson house. Worked on Linda's PC which is still having problems. Working on more Y2K issues. Trying to wrap up testing on the PC applications.

Suresh installed various application softwares such as Framemaker5.5, Applix, Mathematica, Matlab etc with renewed licenses in new file server (replacement for sirius). We still need to install few more softwares. Tests of these installed packages with a client workstation taking place side by side. Test results are satisfactory.

Start working on the final stages of taking the FORE 200 switch off-line but we have put that on hold until the 40M has finished their data run. Resolved a number of network and program issues on the 40M GC and data computers. Most of the problems were resolved with resetting some configuration defaults. However, one machine had been hacked into and the system needed a little more work.

Resolved a number of printing issues. Just as a note when setting up a PC be sure to use a drive with the PS (postscript) option. Many of the printers will take advantage of the extra features this option provides.

When using Norton Utilities. Run the program and fix any issues that it may find. Then remove the program from the system. The monitoring tools the program setup has been causing problems on a number of computers.

Working a number of procurement issues and maintenance contract renewals. Going over the financial items. Working on getting things cleared up on the new system. Continuing support during the transition to the new Oracle accounting system. The number of issues brought to our group has diminished but we still get a couple of items each day.

Started working on and testing the Sharewhiteboard and other programs from SUN. So far things are looking pretty good. After testing is finished with all of the sites we will start checking on how it will work with the video conferencing project Albert is working on.

Worked a number of issues to help get documents out for the DCC group. Spent some time trying to discover why Gary S. is having problems with the modem pool and why we are not able to duplicate the problem. Gary has also spent some time working this issue.

Added a few more users.
