GlueX Start Counter Meeting, October 17, 2013
Minutes

    Present:
      * FIU: Werner Boeglin, Eric Pooser
      * JLab: Eugene Chudakov, Jarrod Fitzpatrick, Mark Ito (chair), Tim
        Whitlatch, Beni Zihlmann

Construction News

      * Tim told us that the aluminum mandrill for construction of the
        foam/carbon-fiber support has been made.
      * We discussed the geometry of the support structure. FIU needs to
        finalize design of the construction fixture and there were some
        questions about the dimensions of the inner foam, carbon fiber
        reinforcement, and the aluminum support ring (all components used
        in the actual detector support). Tim will look into getting the
        latest set of drawings to FIU so that we can continue the
        discussion.
      * The POs to Eljen and McNeal for the scintillator and machining
        respectively ran into a snag in the FIU procurement process. They
        should go out next week.
      * The test stand is 99% complete. There are a few parts left to put
        together.
      * Eric has been browsing the McMaster catalog for parts for the
        assembly jig.
      * Werner has been thinking about the exact materials for bands
        holding the counters on the inner foam as well as the related part
        of the construction procedure; he wants to minimize forces on the
        scintillator.

Electronics

      * Eric report that Fernando will send down all of the cables FIU will
        need to test read-out.
      * We discussed to utility of doing a complete test of the detector
        with the final electronics chain for all channels. Although that
        has been the nominal plan, it may not be the most efficient use of
        manpower. Beni and Mark will discuss what would be needed and
        report the the group.

Installation

    We decided to maintain April 2014 as a target date for installation of
    the start counter.
