Introduction - KR

• The E8 web page has been set up. In addition to items discussed below, it has the usual links to DMT machines, a list of proposed reduced data set (RDS) channels from Isabel, and the operator shift schedule from Ski.

 
• Isabel has been planning for some time to carry out a test of  real-time RDS generation using LDAS during E8, but Stuart has raised a technical issue with the plan that needs to be addressed before the run. Alan Wiseman will organize a telecon to hash this out this week.

 
• E8 schedule: (all times PDT, all events in LHO control room, except final telecon)

• Friday June 7 @ 11:00 a.m. - Review of hardware status
• Friday June 7 @ 2:00 p.m.  - DMT training session (see below)
• Saturday June 8 @ 8:00 a.m. - Start of E8
• Monday June 10 @ 11:00 a.m. - Review of where we stand / tutorials on new features
• Monday June 10 @ 11:59 p.m. - End of E8
• Friday June 14 @ 8:00 a.m. - Next detector characterization telecon (E8 wrapup, S1 preparation)

Interferometer Status - F. Raab

• The Hanford 4K IFO is still recovering from a variety of software changes. Livetime is not good at the moment, but it's hoped that things will be better by the end of the week.

 
• The Hanford 2K IFO is running well, with displacement sensitivity of about 2 * 10^-17 m/sqrt(Hz) @ several hundred Hz and about 3 * 10^-16 m/sqrt(Hz) @ 100 Hz. The bursting in the MICH_CTRL channel (control signal for differential Michelson cavity DOF) seen in E7 and caused by servo loop instability has been fixed, in part by the implementation of the common mode feedback from the arms to establish a strong gain hierarchy and in part by tweaking of servo loop shaping.

 

DMT Plans for E8:

• KR showed a list of E8 participants (aside from LHO operators) and the scimon shift list, which have had only minor changes since the lists posted in early May.

 
• A DMT training session will be held Friday afternoon at 2:00 PDT according to the following schedule:

 
• Introduction to DMT infrastructure - J. Zweizig (S. Marka, D. Sigg may contribute too)
  
  
• Brief tutorials/demos from DMT authors on site:
  
  
• Dave Chin - LockLoss, ServoMon
• Masahiro Ito - glitchMon, magGlitch, (absGlitch, eqMon?)
• Sergey Klimenko - LineMonitor
• Szabi Marka - Irig-B, TimeMon
• Adrian Ottewill - CorrMon, (Linemon?)
• Steve Penn - Xbic
• Daniel Sigg - MultiVolt
• Patrick Sutton - RayleighMonitor, SenseMonitor
• Natalia Zotov - PeakTroughMon
• John Zweizig - BitTest, HistCompr, PSLmon, Slice

 
(Ordering is simply alphabetic by author; volunteers wishing to go earlier than shown should speak up.) DMT authors are strongly urged to provide hardcopy documentation by Friday afternoon to serve as a control room reference.
 
 
• John reported that DMT pre-release version 2.0.2 (development version) will become production version on Friday, although it's expected that many monitor programs will evolve over the weekend. After things settle down following the run, John will put together a version 2.1 for use in S1. There are a couple of monitors submitted by Patrick (see below) that are not yet in 2.0.2, but will be by the end of the week. The new alarm manager is working, and a script utility has been written that allows easy testing of monitors that call the new alarm class. Szabi (who will return from vacation tomorrow) will be writing a graphical web display of alarm status from all the monitors. John will work with Dave Barker on an EPICS interface.

 
• Daniel reported the installation of seven new DMT-dedicated workstations (Sun Blade 1000 with 2 750-MHz CPU's and 2 GB RAM) at LHO (5) and LLO (2). These are meant to host production background monitors, while sand, stone and delaronde will become dedicated to monitor development / debugging and to interactive foreground monitors. The increase in CPU horsepower should allow monitors to examine more channels simultaneously and to look at more features / channel (e.g., track more lines). Initially, the new DMT machines will be visible only to the CDS network,which means one will have to hop to them from the outside (e.g., by way of sand). Eventually, the machines will have the LDAS data disks on site mounted, allowing offline jobs to be run.

 
• A "Physics Mode Button" will be installed this week at LHO to allow the operator to declare that an interferometer is taking good data. Dave Barker will make the button setting one bit in an interferometer state vector EPICS channel. Mike will make an MEDM display for the button. Peter will set up conlog to disable the button / bit when any of a selected set of control parameters changes. Dave Chin will define a new OSC condition that means "both arms locked and physics mode declared". John will use the new condition to define "clean lock" segment tables for the meta-database.

Status reports on DMT monitors:
 

• Line noise (multi-taper method) & inter-channel correlation monitors - B. Allen, A. Ottewill (no update)

 
• Line noise (quasi-monochromatic method) monitor - E. Daw, S. Klimenko, A. Sazonov (no update)
  
  
• Band-limited / seismic noise monitors - E. Daw
  Ed will be running his band-limited RMS monitor and his peak search monitor during E8 at LHO from the LLO control room. Because of limited inter-site bandwidth, he will rely mainly on the plain-text files produced by the monitors, but he will test their DMT viewer interface to LLO. He expects to focus on the peak monitor, using the AS_Q channel, since that monitor is much less mature than blrms.

 
• Bilinear cross-couplings & broad-band non-Gaussianity monitor - S. Penn

Steve now has a stand-alone GUI-driven version of his monitor and will be testing it during E8. He arrives at LHO tomorrow.
 
• Lock transition and servo instability monitors - D. Chin, K. Riles (Dave reporting)

Dave just arrived at LHO and has installed some recent fixes to the OSC package, LockLoss and ServoMon. This week he will put in calls to the new alarm class, define the "clean lock" osc condition (see above), improve the html summary page for ServoMon, and tweak the violin mode thresholds for ServoMon.
 
• Rayleigh behavior monitor (non-Gaussianity vs frequency) - S. Finn, G. Gonzalez, P. Sutton (Patrick reporting)

Patrick is working on an upgrade to the speed of the Rayleigh monitor's histogram display, incorporating some code from Daniel. He hopes to test it during E8. He arrives at LHO on Thursday.

Inspiral sensitivity monitor - S. Finn, K. Schlaufman, P. Sutton (Patrick reporting)

There have been incremental improvements to SenseMonitor since the last code submission to John, which will be tested during E8.
 

Power spectral transient monitor - S. Mohanty (no update)

• Transient identification & event catalog monitors - J. Sylvestre, R. Weiss (no update)

 
• Glitch monitor - M. Ito

Masahiro has completed 90% of his planned upgrades to glitchMon and hopes to have everything done this week.

• Magnetic field and seismic transient monitors - R. Frey, R. Rahkola (no update)
  Mike confirmed that Rauha (who can't make it to E8) has been training the LHO operators how to use his transient monitors.

 

A.O.B

• Next  teleconference: Friday June 14 at 11:00 a.m. EDT (8:00 PDT). This telecon will be held a week later than normal, in order to review what was learned in E8 and to discuss plans for S1. KR will post a preliminary S1 shift list before the telecon.
