GlueX Start Counter Meeting, July 10, 2014
Minutes

    Present:
      * FIU: Werner Boeglin, Anthony Llodra, Eric Pooser, Carlos Yero
      * JLab: Eugene Chudakov, Mark Ito (chair), Nick Sandoval, Beni
        Zihlmann

Electronics Installation at FIU

    Nick is traveling down to FIU this Sunday and will be coming back on
    Friday. Initially he will uncrate the electronics, set-up the
    electronics and cable them up. that should be done by about Tuesday
    afternoon. In the remaining time he will serve as consultant to the FIU
    group as they get tests going.

    Nick is bringing down a laptop with a LabView application to control
    the MPOD. The idea is to tranfer the program to the computer in the FIU
    Lab for use after Nick returns.

Light Tighting Scheme

    Eric stressed that we need to address this issue soon. Mark will
    contact Chuck and form a plan for getting a design.

Detector Construction Status

    Eric gave a presentation on the status of scintillator polishing and
    testing. Please see [19]his slides for details.

    They have a new procedure using a combination of 0.3 micron [20]alumina
    suspension from Allied and 0.05 micron suspension. The counters are
    polished for about an hour with each suspension. Again, after
    polishing, the counters give time resolution consistent with the best
    prototypes. FIU is still refining the polishing procedure. They will
    finalize it soon and strt production polishing.

    The support structure arrived. A test fit of three wrapped counters was
    done and alighnment looked good. The pneumatic foot for the assembly
    jig held the counters well and the ring mechanism works for holding
    installed counters.

Readiness Review

    Some days ago Mark and Werner discussed the date of the review. We
    decided on July 22.

Progress Reporting

    Eric is about to send a formal progress report on the construction
    contract. These will be issued monthly.

Invoicing

    FIU sent its first invoice to JLab. The invoice lacked an itemized list
    of items being charged for. Jarrod Fitzpatrick of JLab Procurement is
    in contact with his counterparts in the FIU Division of Research on
    this.
