GlueX Start Counter Meeting, January 10, 2013
Minutes

    Present:
      * FIU: Werner Boeglin, Puneet Khetarpal, Eric Pooser
      * JLab: Eugene Chudakov, Chuck Hutton, Mark Ito (chair), Sascha
        Somov, Beni Zihlmann

Review minutes from previous meeting

    Chuck told us that the 3-D model was made, but drawings haven't been
    produced yet. That can be done now.

Counter Construction

      * Eric has an email in to Chuck Hurlbut at Eljen. Chuck has talked to
        the guy at Eljen who will run our project. Eric has also contacted
        Robert McNeal about plan to have Eljen do the bending.
      * The next step is to send a prototype counter through whole process.
      * Werner has a new work-study student to work on testing. Eric is
        training him.
      * Eric is also working on the design of the assembly jig.

SiPM Read-Out Status

      * FIU got the ST-2 board back from Fernando Barbosa. It has not been
        tested yet.
      * The next thing to do is the gain measurement do that Fernando can
        finalize the electronic design. The goal is to have a pulse-height
        for minimum ionizing signals that is completely contained in the
        FADC range. This assures that the time-walk correction can be
        applied for the smaller signals where the correction is critical.
      * Sascha reports that 600 SiPMs have been received (for various
        projects, not just the start counter).
      * Want to get a three-counter read-out board as soon as possible for
        the test set-up.

Contract

      * Werner has looked over the example documents for procedures and
        quality assurance from the TOF constract.
      * We will likely broach the deadline for a proposal appearing from
        FSU. Mark will ask Jarrod Fitzpatrick about how to handle this if
        should come to that.
