E9 Preparations (Friday Jan 24 18:00 PST (20:00 CST) to Monday Jan 27 04:00 PST (06:00 CST)

• IFO status (F. Raab)
  H1 and L1 are doing well with spectra minima in the mid 10^-22 Hz^-1/2. Good progress has been made on wave front sensing (4 out of 5 loop pairs of DOF's closed on H1, 3 / 5 on L1). There is hope that all five loop pairs will be closed soon. H1 hardware will be frozen at the end of the day, but work can continue in the control room.
  H2 lags behind (roughly factor of 10 worse in sensitivity @ 100 Hz), but there has been some recent insight into its troubles. An input mirror appears to be missing an anti-reflection coating that would explain high losses in that IFO. Beam clipping and backscattering of light are creating other problems.
  H1 and L1 are locking well, with H2 less reliable. Nonetheless, three locking IFO's are expected for E9.
  KR asked about control room projectors and speakers for DMT alarms. LLO has a new projector in place for displaying DMT figures of merit. LHO will not have a new projector in time for E9. A speaker (and sound card, if needed) for the LHO control room will be obtained in time for E9. A pc will be set aside for display of RayleighMon time/frequency output. Patrick remarked that both interferometers can be displayed on one screen.
  
  
• Scimon shifts are all filled, with ample backup for last-minute cancellations.
  
  
• Scimon shift procedure worksheets were updated in the M2 mini-run in December. Not all updates were completed. Volunteers have been reminded to finish those before E9.
  
  
• Investigation teams (Joint E9/S2) are reminded that E9 serves as a dress rehearsal for S2. Teams should verify software and/or hardware tools works, giving sensible results. A brief E9 report should be given at the February 7 detchar telecon (1 week before S2).
  The calibration team will do full-up calibrations on Friday evening, with daily autocalibrations afterward. The injection team will carry out a modest subset of its planned S2 signal injections afterward the same evening. Mike offered to help with that work at LHO.
  Sergey raised the issue that tracking calibration and other lines has put the main LineMon monitors in danger of  exceeding the required to process each time stride (actually a problem related to the memory buffer). John promised to try increasing the size of the partition on the LineMon machine to make more margin.
  KR was disturbed to realize that time strides can be lost from DMT monitors without our knowing it and urged some thought on how to alarm on that event in the future
  
  
• Additional meetings:
  
  • Telecon Thursday Jan 23 at 15:00 PST (17:00 CST)
  • Inter-site telecons: Each day (Fri/Sat/Sun) at 17:00 PST (19:00 CST)
  • Intra-site shift handoffs every eight hours
  
  
• E9 contact info for DMT authors

• New or developing monitors:

• SenseMonitor (P. Sutton)
  A new, more sophisticated calibration drift correction has been implemented in SenseMonitor, following the prescription Gaby put together last fall for the S1 data, using alpha and beta parameters. The new version of the program seems to work and now uses a config file for setting parameters, which will allow it to be restarted more simply than in the past. The alpha and beta values are trended with the intentions that online search DSO's will be able to make use of them (with one hour latency). Patrick Brady and others are working to make sure those trends can in fact be used in the LDAS environment. John mentioned a bug in the DMT infrastructure that caused a dropout every hour on the hour if a DMT monitor were not synchronizing its output to the hour.
  
  
• ShapeMon (KR for S. Marka)
  ShapeMon looks for coarse changes in spectrum to identify channel hopping. The monitor has an associated epics display that Dave Barker has found useful in tracking down DAQ problems. The monitor is not yet running under the process manager because of a technical EPICS interface issue at LLO, but the monitor will be running privately during E9 at both sites, if necessary.

• SuspensionMon (R. Rahkola)
  The monitor is still under development. Brian Stubbs will be at Hanford over the weekend and hopes to have basic functionality working before E9.

• SpectrumArchiver (T. Olson)
  Tim has posted a preliminary proposed list of proposed channels to archive on an hourly basis, using the S1 RDS channel list as a starting point. Daniel suggest revising the list to be all channels with a sampling rate greater than 100 Hz, about 1000 channels / IFO. Dave Barker is setting aside some disk area on FB3 for spectrum storage. Some discussion ensued on storage space vs resolution bandwidth. It was decided to store with 0.1 Hz resolution up to 1 kHz and with 1 Hz resolution above 1 kHz.  A modified DTT version with easier retrieval of archived spectra is nearly ready for testing. Tim hopes to try it out in E9. His monitor will also eventually provide a daily pdf summary for the elog, but that is unlikely to be ready for E9.

• DMT bug status (snapshot from January 16 of open bugs )
  A list of reported bugs was gone through. Some have been fixed and await independent testing; others are being worked on; still others (low priority) will be worked on once conditions have stablilized in S2. The only potentially critical bug involved a failure mode in the data pusher, which John is confident has been fixed.

• Fred announced that Terry Santini has replaced Jill Berry at Hanford. Visitors should contact Terry instead of Jill in the future.
  
  
• Next detchar telecon: February 7, 2003
