GlueX TOF Meeting, December 10, 2010
Minutes

      * FSU: Sasha Ostrovidov
      * JLab: Mark Ito (chair), Sascha Somov, Simon Taylor, Beni Zihlmann


Review of Minutes from Last Meeting

    We looked over the [19]minutes from last time.

    The construction MOU between FSU and JLab and been signed by all
    parties at FSU and JLab now. Next step is the construction contract.

Prototype Status

    Sasha O. reported:
      * The TDC noise issue has been solved. The CFD in the next slot was
        causing the noise. When moved to a different location in crate the
        noise abated.
      * The VME64 crate he cannot hold more than 2 JLab modules. The desire
        is to run with three: TI, discriminator and F1TDC. Any two of these
        is OK but with all three, the 12 V supply starts to sag. Solution
        was to put the discriminator in another VME crate along with the
        CAEN CFD. A second interface was found, a CAEN VME-USB bridge. Some
        of the driver software needed to be modified for this new
        arrangement.
      * There was a problem gluing up the long TOF paddles. The original
        plan was to glue them in a vertical orientation so that gravity
        holds the joint while it cures, but the new lab space has
        insufficiently high ceilings.
           + Beni suggesting trying to use UV curing glue; it cures very
             quickly. The Detector Group at JLab has experience with this
             glue. Carl Zorn is a possible resource.


Next Meeting

    This was the last meeting of 2010. The next meeting will be Friday,
    January 7.
