  4.  Jack Segal
     *   INFN GEM Detectors - Frame Assembly
        *   Frame sent to have cable mounting plates welded on, returned to Test Lab.
        *   Change in plans to use (2) INFN chamber layers, ongoing discussion with designer regarding mounting and shims for the (2) UVa layers. (The UVa "UV" layer)
