GlueX Start Counter Meeting, February 9, 2012

Minutes

    Present:
      * FIU: Werner Boeglin, Lei Guo, Puneet Khetarpal, Eric Pooser
      * JLab: Eugene Chudakov, Chuck Hutton, Mark Ito (chair), Tim
        Whitlatch, Beni Zihlmann

SiPM configuration

      * We reviewed the [22]Conference call with Hamamatsu representatives
        and the solution we have decided to pursue: 4 SMD-type 3×3 mm
        devices in a row.
      * We reviewed the recently received [23]quote from Hamamatsu for the
        relevant devices. (See Mark for the username and password).
      * We looked at the latest drawings from Chuck, [24]3-D close-up
        version and [25]line-drawing version and discussed various
        mechanical considerations for the read-out design.

Prototype Report

      * Werner has placed an order with [26]McNeal to make a sample
        counter.

Simulation Report

    Puneet showed results recent results from [27]new studies that model
    light collection in the counters. He uses Geant4. He described:
     1. Geometry and set-up
     2. Material properties used
     3. Optical surface options explored

    Results are not inconsistent with what has been observed on the bench.
    See his wiki page for details.
