GlueX TOF Meeting, November 12, 2010
Minutes

      * FSU: Sasha Ostrovidov
      * JLab: Eugene Chudakov, Paul Eugenio, Mark Ito (chair), Simon
        Taylor, Beni Zihlmann


Announcements

    Mark reminded us of the plan to break up the PID meeting into three
    separate meetings: TOF, start counter, and target. See [21]his email
    for details.

Prototype Status

      * Paul is working on setting up the new lab space for TOF
        construction. He found some extra money to purchase
        infrastructure-like items, including a lathe and a buffer wheel for
        polishing.
      * Sasha has been moving to a set-up to use the "Giles" method using
        the new trigger processor.
      * There was a problem with the F1 TDC where the TDC was reporting
        that the "resolution is not locked". This was fixed by configuring
        the TDC to not honor trigger signals on the front panel during
        initialization. In the future triggers can be held off upstream of
        the TDC.
      * Paul has requested a full VME crate from the Fast Electronics
        group. Crates should be arriving at JLab in December.
      * Eugene would like to get a phototube from FSU so that it can be
        looked at in one of the set-ups at JLab.


Mechanical Design

    There is a designer that FSU Physics pays for that is now available for
    work on the TOF. Paul has received mechanical drawings from IU on the
    FCAL geomentry. Paul would like to arrange a meeting soon with
    engineering folks at JLab, FSU and IU to get started on the TOF.

Calibration System

    We briefly discussed options for a calibration/pulser system for the
    TOF. There is not a definite plan right now. There have been
    [25]discussions in the past about the need for a laser system like that
    used for CLAS in Hall B. We might be able to piggy-back off the Athens
    system to be used for the calorimeters.

Trip to Columbia (U. South Carolina)

    We discussed again the idea of a visit to USC to see Ralf Gothe's
    set-up. Paul agreed that it was a good idea and that he could arrange a
    visit, with Sasha, privately with Ralf.

MOU status

    The construction MOU between FSU and JLab has been signed by all
    parties at FSU and is in the process of collecting signatures at JLab.
