GlueX TOF Meeting, September 2, 2014
Minutes

    Present:
      * FSU: Hussein Al Ghoul, Sasha Ostrovidov
      * JLab: Mark Ito (chair), Beni Zihlmann

Collaboration Meeting

    We looked at the agenda for the upcoming [17]Collaboration Meeting. The
    PID session is at 2:00 pm, Friday, October 3. FSU is discussing plans
    on who will present what. Beni suggested that some time should be
    devoted to how beam time should be used during the commissioning run.

Review of August 26 Meeting

    We looked at the [18]minutes from the last meeting.
      * The issue with lack of TDC hit efficiency is still under study.
      * Sasha tried to take data this past weekend without success. He did
        get VNC going to the Counting House, but it was still slow.
      * Beni pointed us to [19]information about which nodes to use in the
        Counting House. There is a lot of useful information there for
        online data taking.
      * Aristeidis continues work on the event display. He is working on
        getting "TOF point" information from JANA rather than from his
        custom class. He is noticing that the JANA info has x and y
        coordinates, but never both as he would like.
      * Beni cautioned us that we need to check out ROOTSpy from the Hall D
        Subversion repository, not the the 12-GeV repository. The version
        on the latter will not work for Hall-D-related stuff right now.

Time Calibration

    Sasha has coded his algorithm for iteratively throwing away problematic
    tracks and in the the debugging process now.

Action Items

     1. Check-in alpha version of the TOF event display. (Aristeidis)
     2. Take more data. (Sasha)
     3. Debug time calibration program. (Sasha)
