GlueX Start Counter Meeting, November 18, 2010
Minutes

      * FIU: Werner Boeglin
      * JLab: Lei Guo, Mark Ito (chair), Simon Taylor

Announcements

    This was the first dedicated Start Counter Meeting, as [17]announced
    earlier. Nominally we will meet every other Thursday at 3:30 pm.

Prototype Status

    Werner and Lei reported on several items.
      * Werner is leaning toward read-out with SiPM's, especially in light
        of the decision to go ahead and use them on the BCAL.
           + We need to check that the radiation dose upstream of the
             target but close to the beam line is operationally acceptable.
           + Werner has one at FIU to look at.
      * New scintillator material has arrived at FIU.
           + Light output of the new counters will be evaluated with the
             SiPM.
      * Bending studies are proceeding. The plan is to measure light output
        before and after bending on an older 5 mm counter.
      * Student manpower
           + Eric Pooser: graduate student, working on prototype hardware
             studies
           + New undergrad hired, learning polishing, light output
             measurement procedure
      * Lei is talking to the company that is making the light guides for
        the central TOF of CLAS12. They are in the acrylic furniture making
        business. They were originally contacted by Vitale Baturin. It
        looks like they can do the polishing of the scintillator for us.
      * Lei is also trying to find some samples of ESR wrapping material,
        so far without success. He and Werner will contact Paul Eugenio on
        this.


MOU

    Werner feels that we are close to a stage where we should start working
    on the construction MOU between FIU and JLab, especially if we decide
    on the photo-detector. Mark will send him some samples of recent MOU.
