GlueX Start Counter Meeting, August 7, 2014
Minutes

    Present:
      * FIU: Werner Boeglin, Eric Pooser
      * JLab: Chuck Hutton, Mark Ito (chair), Tim Whitlatch

Approved for Construction

    The [22]readiness review was held last Monday, August 4. The start
    counter was [23]approved for construction. There is a [24]video of the
    review, which include a tour of the lab at FIU.

Schedule

    We discussed the construction and installation schedule, which is now
    very tight.

    Tim would like to have everything installed in the Hall by September
    26. That means that the start counter has to be delivered to the Lab by
    the first week of September. The FIU team thinks that this is do-able.

    Tomorrow, FIU will do a test assembly of the counters on the support
    structure. After that they will have a clearer picture of the
    construction schedule.

    At JLab, the target cart for the commissioning target has been made.
    Installation of the arm for supporting the start counter box is
    underway. Cables have not been strung in the Hall yet.

Light Tightening

    We went over the [25]drawings that Chuck sent around two weeks ago. A
    plastic ring, made of two separate semi-circles, covers the outside of
    the ST-1 boards. The inner edge of the ST-1s will be sealed against the
    support with either an O-ring or caulk. There was agreement that the
    scheme looks good. We will have to start manufacturing of the plastic
    ring by next week to have it ready for installation in early September.

Run Documentation Items

      * Mark put together draft [26]shift instructions last June.
      * We have to provide a start counter contribution to the
        [27]commissioning plan.
      * There will be a meeting next Wednesday to present plans for
        calibration during commissioning. Werner will prepare a slide for
        the start counter.
      * Eric sent in start counter contribution for the [28]TDR some time
        ago.
