GlueX TOF Meeting, January 16, 2014
Minutes

    Present:
      * FSU: Paul Eugenio, Sasha Ostrovidov
      * JLab: Chuck Hutton, Mark Ito (chair), Beni Zihlmann

Installation

    Paul was at the Lab earlier in the week with Hussein (who is still in
    Newport News). A lot of progress was made in preparations for
    installation. There are a lot of adjustments/height-settings that have
    to be done and the details of the procedure are being worked out. Tom
    has been consulting on details as well. A few modules were laid out on
    the frame to test the fit of the various components.

    The number of the threaded standoffs made turned out to be much fewer
    than required. FSU is making the balance now and they should be ready
    by next week when Paul goes back to the Lab on Tuesday. Turns out there
    are already enough of the corresponding nuts on hand due to an extra
    order that came from McMaster.

Electronics

    Paul will return the CAEN TDC module borrowed from JLab to Fernando.
    The FSU module was sent back to CAEN for repair and has now been
    returned.

Testing Results

    Sasha has been working on test results from the short paddles. He has
    got things down to about 150 ps, including application of time-walk
    corrections. The standard modules gave 90 ps, but they are two-ended,
    unlike the short paddles.

Contract

    A contract extensions has been approved. Paul will look into getting a
    signature on it at the FSU end.
