E6 Preparations:

• Introduction - KR

 
• The E6 run will start at noon CDT (10:00 a.m. PDT) Friday November 16 and end 72 hours later on Monday the 19th. Daniel Sigg and Szabi Marka will be the run coordinators at Hanford and Livingston, respectively.
• This meeting is meant in part to review where we stand on E6 preparations and to find out if there are any special requests from the investigation teams.
• Running will be in 24-hour mode at Hanford and Livingston with two operators and two scientists on shift.
• Today is the deadline for getting new or revised DMT monitors to John for incorporation into the standard lineup for E6 (see below).
• Szabi has set up the E6 web site, modelled closely on that of E5.

 
• Interferometer running configurations - S. Whitcomb

 
• There will be some environmental disruptions at the start (Friday afternoon) and end (Monday morning) of E6 at both sites, because of building construction at LHO and nearby logging at LLO. There is likely to be significant environmental noise at LLO during the day Saturday also. It's expected that the prime data taking period there will be sundown Saturday until sunrise Monday.
• Nominally, both the LHO 2K and LLO 4k will be locking in full recycled configuration. The LHO 4K may be in single-arm or power recycled Michelson cavity mode, single-arm more likely. The LHO 2K has been a little cranky in recent weeks, but it's hoped that the problem(s) will be fixed by next week.
• Data taking at LLO must compete for time with intensive, ongoing commissioning activities. It's hoped that roughly half the good available observing time will be devoted to data taking, the rest to invasive measurements. Coordination of data taking vs commissioning with data taking at LHO will require regular meetings before and during the run (see below).

 
• Run planning - D. Sigg, S. Marka

 
• Running plans at LHO are similar to those for E5, except for a major change in data recording arrangements:
• Frames will now be 16 seconds long instead of 1 second.
• Only small reduced data sets will be written to disk on fortress. The usual large standard "reduced" data will not be written because it's expected that the on-site LDAS archive will be accessible to online analysis during and after the run. In addition, the DAQ disk buffer will allow a look-back time of about three days.
• Running plans at LLO will be very similar to those for E5. A "reduced" data set will be written to decatur, as before. Szabi will post a proposed set of LLO RDS channels for investigators to look over.
• Inter-site telecons will be held regularly at 8:00 a.m. and 8:00 p.m. CST, starting Thursday evening the 15th. It is hoped that tentative decisions on special running periods, including splitting time with commissioning at LLO, will be made at the Thursday evening meeting.

 
• Scientific monitoring shifts - KR

 
• The current list of scientific monitoring shifts is now complete.
• As for E3-E5, shifts will be synchronized at the two sites, with day shifts starting at 6 a.m. at LHO and 8 a.m. at LLO.

 
• Investigations:
  
  
• Organization - There is a confirmed leader for all thirteen E6 investigations, but some efforts are thin. More volunteers are most welcome. Two additional comments:

 
• No leader has been found yet for the lock loss study at LHO.
• In this first round, the signal injection team will plan to inject only inspiral waveforms to test the full data pipeline. A more ambitious effort involving other waveforms and with more participation from upper limits groups should ideally be carried out before E7.
  
  
• Special data channel requests and channel status:

 
• The signal injection team will need a special RDS that includes the signal test point channel. Peter will set something up in advance.
• Fred remarked that the LLO reference cavity temperature channel needed in tidal modelling studies did not seem to give sensible data in E5. He will contact Joe Kovalik about the problem.
• Rana mentioned that the new OSEM sensor channels on the large optics controllers at LLO are not yet physically connected. The new DC-coupled coil currents are connected, however.
• Mike reported that the calibration team will also have a special RDS running during swept sines.
  
  
• Special running requests:

 
• The calibration teams at LHO and LLO will try to carry out swept-sine measurements before the run begins, most likely Thursday night. The uncertainty is greatest at LLO because of the ongoing commissioning conflicts. Szabi and Rana will try to work out a schedule with Rai in the week preceding the run. It is expected that several hours of quiet time will be needed to carry out an initial swept sine.
• The signal injection team hopes to need only a few minutes of simultaneous locked-IFO states at the sites given sufficient preparation.

 
• DMT Monitors - J. Zweizig:

 
• John has recently received new or revised code for the following DMT monitors to be run during E6:
  
  
• Glitch monitor from Masahiro Ito (with modifications due to Natalia Zotov)
• Magnetic field transient monitor from Rauha Rahkola based on Masahiro's glitchmon
• Band-limited rms monitor from Ed Daw
• Lock loss and servo monitors from Dave Chin 
  
  
• John has also updated the data accessor infrastructure to make use of frame tables of contents, an improvement which has brought the typical workstation cpu usage fraction per monitor down to about 6% (25% per CPU).
  
  
• All of the DMT monitors to be used during E6 will be started up and left running several days before the run to give time for shaking out problems.
