GlueX TOF Meeting, September 13, 2012
Minutes

    Present:
      * FSU: Paul Eugenio, Sasha Ostrovidov, Randall Smith, Ian Winger
      * JLab: Eugene Chudakov, Mark Ito (chair), Tim Whitlatch

Announcements

      * The construction contract between FSU and JLab has been signed by
        both parties.

Review of Last Meeting

    We went over the [23]minutes from the August 30th meeting.

    FSU reported last time that the bent plates sent from JLab did not look
    as good as expected. Tim thought we should try them in the mini-TOF
    anyway and see if they cause a problem.

Mechanical Design

    Ian showed a drawing of a [24]fixture for gluing light guides to
    scintillator. The plan is to add a temporary counterweight to each
    light guide so that the combination of light guide and weight will sit
    on top of a scintillator bar without additional clamping or support.
    Gravity will then supply the clamp for gluing. He showed a sample
    weight. The overall fixture can be rotated 180 degrees to glue light
    guides to the "other" side.

Mini-TOF Construction

    Current activities include:
      * polishing light guides
      * more UVT was material ordered and received
      * making the longer light guides for the central counters
           + design in hand, but never made before now

TDC Implementation

    At some point we need to identify manpower to make sure that the
    ancillary boards needed to incorporate the CAEN TDC's into the data
    acquisition are produced and their use understood. Only prototypes
    exist at present. Hall B will be using them, so we are not alone in
    having this need.

Calibration and Alignment

    Sasha will produce a note on the current plans. It should be ready by
    the Collaboration Meeting. He is running some Monte Carlo simulations
    to test the ideas.

Technical Design Report

    Paul is making progress.

Contract and EVMS Status

    We will need to make pick points for the EVMS plan before the end of
    the month. Mark will consult with Beni and circulate a draft.

    We plan to have a meeting next week to discuss details of invoicing and
    payment.
