GlueX TOF Meeting, March 13, 2014
Minutes

    Present:
      * FSU: Sasha Ostrovidov, Aristeidis Tsaris
      * JLab: Chuck Hutton, Mark Ito (chair)

Installation Update

    Two more mods were made to the install configuration.
     1. Holes in the clamping channels were made larger to accommodate
        slight repositioning of the connecting studs.
     2. We have reduced the number of studs used in the clamping; some of
        the outer studs will not be installed.

    Chuck reported that as of last Friday the second layer of counters were
    laid out on the saw horses. Work on the support rails (attached to the
    forward support structure) is largely done; the rails are in place.
    There was a slight adjustment to the bearing attachment to the rails; a
    hole was slotted to accommodate the slightly wider TOF frame.

    The next thing to do is to install the steel phototube shields on the
    frame.

    Tim Whitlatch thinks that installation should be done by the end of the
    month.

Construction Documentation

    Now that we are approaching the end of construction and installation,
    we need to think about having the Lab capture construction procedures
    and assembly databases as the final step of the contract. Chuck has all
    the procedures; he will check with Paul Eugenio that what he has is
    indeed complete and up-to-date. Sasha will send the SQLite database to
    Mark with the software to read it.

Software Geometry

    Beni Zihlmann checked in changes to the HDDS specification and
    reconstruction code to account for the half-width counters. Simon
    Taylor helped also; he fixed a bug that was discovered with the
    half-length counters.
