LIGO Weekly Site Telecon (Lindquist)

• Procedure Manual:  still not done, hopefully (again) will be by next week for distribution to sites and campuses.
• Budgets:  travel costs are exceeding budgets. Areas overrun include the Director's Office, the Business Office, Hanford and Livingston Commissioning accounts, and MIT.  Examples of causes include support for science runs and LSC meetings where attendance is important for many people.
  
• Cost Transfers:  A number of cost transfers have been requested.  This is being resisted unless there is a significant mistake or significant potential cost savings.  A large number of cost transfers attract attention during audits and if it is necessary to go back over 90 days, the bureaucratic hurdles are daunting.  We can move the costs, but the preferred approach is to get it right the first time (we are providing tracking reports now and greater attention is being paid, hence the requests for transfers) and to adjust budgets if needed.  The procedure manual is expected to help.
• Teleconferencing:  Raindance has been selected as our new provider of teleconferencing services.  Calls will, as previously done, be charged against the Director's Office, the Business Office, and the Site Commissioning accounts.  Charges for extraordinary calls (e.g., international LSC working group meetings lasting eight hours on a Saturday) will be considered on an individual basis.

SUPPORT (Baldon, Lloyd, Tischler)

>Irene Baldon

• A great portion of my time has been tied-up with testing out a new P-Card Program which after at least an entire day attempting to make it work it still appears, at least to me, seriously needs reworking.
• Also at least two (2) full days of my time has been taken up with working with Raindance Reservationless Conferencing, selected as the new replacement for AT&T Teleconferencing, adapting it LIGO's needs, setting up cards and pins for frequent users, distributing these, and cancelling AT&T standing calls as users become comfortable with Raindance.  Raindance will be charging LIGO $0.24/minute/caller as opposed to AT&T charging LIGO $1.00/minute/caller.  As significant savings to LIGO.
• Processed the paper work eleven (11) new/revised trip.  There are eleven (11) trips in various stages of completion before ticketing can be done and/or paper work completed.  PLEASE NOTE:  That 2004 SURF travel has started and this year I'm currently working twenty-five (25) travel arrangements, including domestic and foreign.  I continue to work closely with Terry Gunter and LIGO/Hanford personnel in acquainting them with travel procedures, etc.
• Completed nine (9) Expense Reports and there are thirty-four (34) reports yet to be done.  I continue to contact travelers who have outstanding Expense Reports (more than one (1) month old) to ask for their cooperation in sending me their receipts so that these can be closed in a timely manner.  Presently is are seven (7) reports more than 30 days old.
• Reconciled ten (10) P-Card items which required numerous phone calls to hotels, car rentals, etc., in order to track down which traveler incurred which charge; and the pulling of each traveler's file to assure that charges are correct for each fee incurred.
• Continued to cover the Project Office, Barry Barish's and Donna Tomlinson's Office when called upon.  Worked on the preparation and distribution of the Travel/Vacation Itinerary for April 12, 2004.  Arranged twelve (12) new or revised AT&T teleconferences and two (2) new reservation on the LIGO Calendar.

• Processed the usual invoices for payment. Tracked and followed up on invoice problems.
• Processed the usual requisitions, change orders and payment requests.
• Continue to monitor contract and blanket order encumbrance and notify task managers when supplements are needed.
• Jim continued with data entry in the LIGO database and helping out in the DCC.

CDS

CDS Software

•  Updated all front end code to latest rev. as loaded at LHO.
•  Loaded new ASC code which supports new IO WFS configuration; hardware still needs to be installed.
•  Modified and loaded new HEPI code to match latest hardware I/O connections. Testing will start tomorrow.
•  Installed a third linux PC to match configuration at LHO; new PC runs lsc and asc epics software.

CDS Hardware

• Talking to Sazabi about the atomic clock.
• Flavio and Jay are working on a schedule to present to the commissioning team.

• The 3rd order cheby prototype is working and appears to perform as predicted by the simulation.
• Discussions on the type of filter that we need and the requirements for the final design continue amongst the commissioning team. We should have a better idea by next week.

• The offset that was observed on the whitened version of the PD monitor signal was due to the large bias currents of the AD827 amp. It was swapped for an OP270 and now the offsets are <1mV.
• Flavio and Peter K are looking into the 1-2MHz resonant feature in the current shunt response.

• Ben has an updated schematic that he sent to Vern for comments. Vern has a few additions. They will be incorporated and the design presented to the commissioning team for review.

• X end at LLO done last week and is being tested.
• We need to order the 50 pin cables needed for the Y end, etc.

• Rounding up equipment for tests.H

• Sent 4 new pier interface modules to LLO for installation.
• The drawing for the system schematics for the corner station is currently on hold.  I have 26 pages with the parts in place, but I need to find out what the racks will look like before I can label any of the cables, modules, and feedthroughs.

• 2 ea 166MHz PDs for the 40M are complete except for final tuning.
• Addtional pier interface modules in test.

40 Meter Interferometer (Weinstein)

• Osamu is preparing to lock the PRC with double-demodulation (DD) at the SP. A DD RFPD is in place, the DD will be done with a pair of IQ Demod boards, and the LO RF signals are in place (at 166+33 and 166-33 MHz). We need to do some wiring of the LSC rack to get the signals into the LSC system, and are now looking into the needed software changes, if any.
• Jay, Osamu, and Rob are going over the requirements for LSC hardware and software for the full dual-recycling lock acquisition, and Rolf knows that we're thinking about it.
• Rolf and Alex are thinking about implementing a general-purpose "math block" in the digital controls software, which we could use for dither-locking the PRC.
• Locking of the Fabry-Perot-Michelson (FPMI) is currently hampered by a (new) problem with the PSL (see below). It can be done, but there is apparently a problem making the transition between locking of XARM/YARM and CARM/DARM that is not understood and is under investigation.

• The PSL is starting to misbehave again, in a new way. The frequency reference cavity (FRC) error signal is oscillating in a funny way, suggesting saturation. Osamu suspects the FSS fast (PZT) loop. Under investigation.
• Steve & Osamu decreased the PSL NPRO #238 power output from 712mW to 504mW by adjusting the doide current potentiometer from 2A to 1.7A. DTEC fell from 1.7 v to 1.25 v (that was the point; the PSL trips off when DTEC exceeds 2 v), and the MOPA power fell from 12.1 W to 11.0 W. The PSL has been performing stably since then. We think we're out of the woods with regard to heating, but we still await an NPRO heat sink from the shop. That will hopefully arrive and be installed next week, at which time we will fully close the MOPA cover and hope that the heat (DTEC voltage) doesn't rise unacceptably.
• We intend to adjust the PSL slow loop temperature change in the EPICS state code.

• Fumiko has tried to implement an oplev servo filter based on what she found at the sites (modified with FOTON to be more appropriate for our 5" optics). She was unable to see a reduction in P/Y noise (as measured by the OSEMs). She will pursue this work systematically.
• Rob has finished laying out the POB beamline, and is hooking up the electro-optics: a ccd camera, an RFPD, and a QPD.
• We now have 12 QPDs installed and being read out: IPPOS, IPANG, IOPOS, IOANG, MCR, MCT, TRX, TRY, POX, POY, AP, SP. We need one more, POB, and an additional readout channel. Ben has delivered the QPD itself; we have to either instrument a new readout channel or borrow POY's.
• Shihori has aligned all the QPDs except for POB, and TRX and TRY. She will do those next.
• We now have 3 electro-optic shutters (EOS): at MCR, SP, AP. The MCR one has been working for many months. Shihori and Osamu got the SP one working, and Shihori measured the transmittance vs HV; a nice cosine curve. She will document it. There are problems with the one at the AP, which may be due to bugs in the controller. Under investigation.
• We now have 4 mechanical shutters under EPICS control (PSL, MCR, AP, SP) and 4 under manual control (MCT, POB, POX, POY). One shutter is not functioning and has been returned for repair/replacement.
• EPICS code to shutter the PSL during vacuum transitions will be implemented soon.
• Osamu, Steve, Rob and Shihori have cleaned up all the optical tables, removing all excess optical components for storage, and ensuring that all beamlines are fully instrumented and laid out as in the drawings.
• The PSL table is now grounded to the vacuum enclosure, as are all other optical tables.

• We now have Marconi signal generators for all required frequencies (29.5 MHz for MCR, and 33, 166, 133, and 199 for the main interferometer, all phase-locked to multiples of 33 MHz).
• Ben brought over LSC RF distribution boxes for the 133, and 199; not needed for 166, only one IQ demod board needs it. There are heliac cables for the 33 and 166 to the LSC rack, and Bob ran some temporary RG405 for the 133 and 199; more heliac cable is on order.
• At Osamu's request, Ben removed (and jumpered across) the output attentuators at the end of the RF AM stabilizers that go to the EOMs. Osamu measured the maximum modulation depth for 166 MHz to be 0.3; more than enough, and easily turned down to 0.1 with the EPICS slider. The 33 MHz is probably much deeper, but will also be turned down to 0.1.
• The 166 MHz and 133,199 MHz RFPDs show oscillation at 500 kHz. This is a known problem for RFPDs with low light level, with a known fix, and Ben will implement it.
• Ben cured the long-standing problem of the varying monitoring readout of a couple of Thorlabs photodiodes on the PSL (PMC transmitted DCPD and FSS transmitted DCPD), by tying the "Guard" pin to the signal "Lo" pin (discovered after reading the 96 page manual for the 3123 ADC). He will now investigate the PSL DAQ channels, some of which have been railed forever.
• Ben continues to work on the redesign of the RFPD board, with Vern Sandberg. They are working to incorporate a few new features that would be nice to have. Ben plan to give Dennis a schedule of development by the end of this week.
• Ben is updating the system wiring schematics for the 40m Auxiliary rack, in order to reflect the as-built condition.
• 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.
• Ben Olson continues to diagnose problems with the STACIS seismic isolators. Two of the 3 isolators in the south end are working well, the NE isolator is behaving badly. Under investigation. Steve will locate the STACIS servo extender board or order a new one.

• Steve is cleaning up the 40m lab, moving excess optics and equipment to cabinets in the east arm, and getting rid of surplus equipment such as old 40m racks full of obsolete electronics.
• Bob tied down the monitors in the control room for earthquake safety.
• Bob is plumbing up new "clean" oven C.
• Bob will decommission "dirty" oven D, will surplus it, and will recommission old oven C as a new "dirty" oven D.
• Bob is exploring building a new very large bake oven for AdvLIGO.
• Bob is building OSEM diodes for Janeen (AdvLIGO MC triple) and for the 40m.

Thermal Noise Interferometer (Libbrecht)

LASTI (Ottoway)

Data Analysis and Computing (Lazzarini)

• Continued testing the latest SAM-QFS patch using samtest with 9940A drives and T3 disks.  Some bad behaviors kept us from installing the patch on the ldas-archive system this week.  I am continuing to investigate.
• Continued deleting files in HPSS.
• Changed IP numbers of 3510s to make the ldas-archive private (admin) network consistent (FC switch, 3510s and T3s are now all on the same subnet).
• Worked on SAM problem where releaser log got near 2Gb and releasing quit working correctly resulting in /archive filling up.  Archived outstanding files to tape and ran samfsck, recovering disk space.
• Got Arlo Ruiz at Sun to ship 4 T3 disks to CIT (should be arriving today).

• Setting up Tripwire for ldas system. Configuring rules for tripwire.  Compiling TW for Solaris 9 machines.
• Rebuild array for datacache3.
• Installed memory for ldas-cit 880.
• Still working on tw_cli for datacache, I am not happy yet with the reporting to the system logs.

• Worked on V880 memory problem.
• Generating S1 L3 frames for Stochastic group.
• Finished loading S2 and S3 L1 frames into LDAS-CIT cluser for use by Condor jobs.
• Renewed the T3 maintenance contract with Sun for another year.
• Renewed the LHO, LLO, and CIT Copper GigE switch maintenance contract with Foundry for another year.

• Troubleshot and reinstalled firmware on dmt raid array after power outage.
• Built condor on cluster and ldas-grid.
• Rebuild NIS on cluster and ldas-grid.
• Configured and started LDR for transfer of new data sets.

• Crossmounted nodes'  disk to ldas-pcdev1.
• Configuring NIS+ client on ldas-pcdev1.
• 2 T3 disks crashed today in t3-13 and t3-3.

• Level 1, 2, and 3 createrds jobs are running at LHO and LLO every 100,000 seconds on 1000 s of raw frame data.  This is monitored daily from http://ldas-jobs.ligo-wa.caltech.edu/dsorun/cgi-bin/index.cgi to make sure our systems are working and ready to archive and reduce data between runs, for example in the event of an external trigger such as a gamma ray burst.  (Automated archiving and reductions of data associated with an external trigger, initiated by an operator, is still under construction.)  The LSC should note that raw frame data is not archived or reduced between runs except upon requests to LDAS. Please email Greg Mendell <gmendell@ligo-wa.caltech.edu> or Ben Johnson <johnson_b@ligo-wa.caltech.edu> if you need raw frame data archived or reduced at LHO. We will consult with LDAS and get back to you. At LHO the framebuilder disk cache currently holds 92 hrs (3.83 days) of raw frame data, so request need to be within that time frame before the data is deleted by the framebuilder.
  

• ldas-pcdev1 has been set up on LDAS and GC networks. Working with Christine Barker on setting up GC user accounts (NIS+, autofs etc.) for the machine.
• Installed host certificate and requested 'datarobot' certificate for ldas-grid. Initial tests on gsi-ssh into the box have been unsuccessful.

• Archived bandwidth usage can be seen at http://teche.ligo-la.caltech.edu/mrtg/archive/ under the dated folder for the week of interest.
• Actually making progress with LSU on the network issues we have been having.  I need to contact them next time it happens so that they can contact Bellsouth within 48 hours since that is how long their logs last.
• Having file system corruption on the Linux file server.  I am still working on this issue, and I am a bit nervous about the state that it is in.  We are working on a solution but the next 48 hours will be critical.
• Moved a lot of equipment into the two new racks including two new UPSs, 3 Solaris servers, 5 PC servers, etc.
• As usual, some firewall updates.
• Looking into some strange log entries from my firewall.  Haven't had time to determine the problem yet, but this will have to be looked into next week if the file server issues are taken care of by then.
• Replaced two failed hard drives on one of the RAIDs on Decatur.
• Ordered some software for Katrina and Rich Abbot to use for web development for HEPI stuff.
• Ordered several pieces of hardware to replace failed items, including our server KVM.  Warranty was expired on it and it will cost about $2k to replace.
• Discussed several billing items with LSU over the Internet bill.
• Looking into archiving/deleting several locked accounts at LLO.  They have been locked for about 18 months and no one has complained, so it is time to remove  them from the system.  Need to decide how I am going to archive these files.  I think I will start burning them to DVD and storing somewhere.
• Several miscellaneous user support issues.

• Network usage can be seen at http://www.ligo-wa.caltech.edu/~christin/mrtg/ 198.129.208.1_198.129.78.122.html
• New staff member orientation and setup of accounts and office space.
• Working with Mike Pedraza on PC audits and upgrades.  Thanks so much to Mike for all his help!  He has upgraded several computers to Win2k as well as securing and updating many other PCs.  He also reinstalled Win2k server and I now have a working Windows server!  Some changes that will take place because of his visit are that the Administrator user account will have the user name changed, the password changed and lengthened and the password will not be given to the users.  I will also have to start a regular program for updating every computer.
• Still finishing up the software install and license upgrades for the new application license server.
• Spoke with the PNNL/ESnet representative.  They are planning on changing our connection from OC3 to GigE and are currently looking at what hardware changes will be needed.  Presently they are researching media converters.
• Put the latest Solaris patches on all my Sun boxes in response to the hack at ITS at Caltech.
• Misc. user support.
  

• Working at LHO this week:
• I have been going through PC's and Laptops, checking network/registry settings and making some changes to enhance the network. Patching up security holes by stopping services that are not being used, but allow hackers to use these types of services as backdoors. Running windows updates installing critical/security updates and service packs. Going through event viewer looking for system & application errors. Correcting all errors that I find. Defragmenting hard disk. Removing adware & spyware.  Keeping Christine updated on all my findings. Making a few suggestions to Christine on ways to better secure the network, referring to the windows side of things.
• Reloaded two visitor workstation's. These were win98 installs that I wiped clean and loaded win 2000 pro. I also loaded all GC software and a few engineering packages that were loaded from the previous load.
• Loaded a NTSRV for Christine. This sever is going to be used for backup purposes.
• Attended Microsoft security meeting,(San Diego) that was very informative, in regards to security.

• Finished the tcl/expect script to program the ap2000's.
• Began replacing the rest of the ap1000 AP with ap2000's.
• Worked on some misc. user problems with wireless access.
• Set up a new account and gave the nickle tour to Mark Turner.
• Many more hours of work on e-mail and spam.

• CaJAGWR website: Videotaped the last talk, captured and compressed it for web posting. Posting updates to the website.
• LSC website: Working on the website for the upcoming June meeting.  Incorporating an ecommerce interface into the website. Posted updates to documents at the general LSC website.
• LIGO website: Updates to various pages and usual upkeep. Addressed a DCC issue. User support at Project Science.

• A number of items to address this week. The wireless access points are being swapped out with updated units. Just as a note, we need at least 72 hours notice before adding a MAC address. Adding a MAC address requires the units to be rebooted and takes some time to get all of the config files propagated to the different units. So, people arriving and expecting immediate wireless access without sending the needed information before hand, will be disappointed.  Also, as a reminder, do not use the e-mail aliases used for general broadcasts without permission from LIGO management. These aliases are for LIGO related business only. Any exceptions must be signed off on by someone in LIGO management.
• Spent time assisting Lisa with the e-mail spam filtering. This is another area of concern. When someone is notified of a questionable message, they need to respond ASAP. The message stays in the queue for only a few days before it is automatically discarded.  As can be seen from the e-mail statistics there is a lot to go through. The quicker the response the lesser the chance of a legitimate message being lost. I have received a number of messages from people noticing that the amount of spam has diminished. It will probably never be completely eliminated but with the present tools it should be somewhat manageable.
• Purchased a new lens for one of the Webcams. So far it is looking pretty good for use in one of the conference rooms. A few minor modifications are needed before I start testing in the SCR.
• Worked on a number of PC's. Most were reinstallations of s/w and upgrading the patches.
• Helped Irene with her connection to the new version of the P-Card s/w.  From the short period I spent getting things to work for Irene, I would say the pkg. is not ready for prime-time yet.
• Made a number of updates on the DNS, host server, account server and web servers. All were requests but we are working on changes to accommodate the patches needed on a number of machines.
• Added and removed a number of accounts. The accounts removed also had their files/data removed from the system. If needed they can be restored from backup tapes. This process will continue as we are getting ready for more SURF students and visitors.
• There are a number of matlab fonts that have to be installed in order for remote usage to work correctly. Albert has supplied the font listings and instructions for the unix side. The instructions for the exceed font problem were pretty explicit and do work in resolving the problem on the PC side of the house.
• Assisted Ed C. with a number of equipment items.
• Started work with Albert and Stuart on some LDAS/GC logistical issues, as it appears the support from GC for LDAS related issues is going to increase.
• No major procurement issues this week which is a nice surprise.
