GlueX TOF Meeting, January 5, 2012

Minutes

    Present:
      * Switzerland: Beni Zihlmann
      * USA: Chuck Hutton, Mark Ito (chair), Elton Smith

PMT Purchase

    We discussed the options, some old, some new:
      * All 10-stage tubes, no amplifiers
      * Some 8-stage tubes on the high-rate counters with external
        amplifiers
      * All 10-stage tubes with external amplifiers for counters whose gain
        starts to sag

    We need more information on how the 8-stage tubes perform in the FSU
    test set-up.

Mechanical Design

    Chuck is still considering the TOF-door option as a way to ensure
    access to tubes that may have to be changed. In any case the current
    plan is to allow then entire array to be assembled on the floor
    horizontally and then craned into place.

    Chuck is still waiting for information on the latest light-guide design
    for the half-width counters.
