Elton

      * magnet OSP is getting signed off, retrieved from Eugene's queue
      * Patrizia Rossi, operating from long distance but she is willing to
        sign
      * Tim: magnet at room temperature until
          1. OSP sign off
          2. vacuum valve switch panel fixed
          3. Creel items dealt with
          4. ODH postings changed and all-staff memo sent
      * Elliott: controls ready to go
      * two weeks to get to nitrogen temperature according to Jonathan
        Creel
      * plans for January: go to 4 K, will take three or four weeks
      * power-up review on Jan. 9
      * Yi: PXI system is ready, communications with EPICS up
           + ran communications over weekend, ran stably
           + fast data to EPICS server worked well
           + PXI and PLC connection good

John

      * FCAL frame arrived Fri. morning
           + unloaded and assembled and put on platform today
      * Elton: no-cost extension to contract with IU to do design and
        fabrication of dark room, finally got signed
      * will bring John Frye [?] here in mid-January
           + he designed darkroom
      * start stacking before end of Jan.
      * Elton: hiring process
           + scientist I position advertised
           + 40 applications
           + hoping to hire two, scheduled for but not completely approved
           + will interview 6 people
           + committee met on Fri. sans Glenn
                o made list of non-JLab candidates, interviews starting
                  middle of Jan.
                o will meet at beginning of Jan. to discuss internal
                  candidates

Tim

      * tagger magnet will be delivered in January

Ivan

      * last week issue with gluing tiles
           + increase temp of glue, to 40 C
           + gives strong glue joint
           + Note: material is BC-600
           + tiles are well polished
           + WLS attach from side
           + easily peeled off with old temperature
      * received the fixture for gluing
      * calibrated new PMTs for Franz Klein and Dan Sober, was finished
        Friday

Sasha

      * we have base and tube from Hamamatsu for fixed array, checking rate
        performance
           + already calibrated gain at different voltages
           + 1300 V normal operating voltage, see single p. e. peak
           + also tested at 900 V
           + will use Vladimir Popov's amplifier and divider
      * contract with Richard: dispute resolution issue resolved
      * Catholic proposal has been sent
      * trigger commissioning:
           + got stuff from Vardan, can initialize boards via run control
           + will move this to read-out list
      * discussed interface with database with [?]

Simon

      * working on geometry for simulations
           + many changes to CDC implemented
           + BCAL with read-out box needed work
           + FDC too
      * working on extension to rare eta decay proposal
           + η -> e^+e^-γ
      * looking at PID with FCAL
           + identify hadronic showers using dE/dx

Hovanes

      * PXI to EPICS work: write data to ROOT file
      * helping Beni with prototype of HV GUI for CDC and FDC

Dmitry

      * plan is to switch to CCDB in January, some work done on mirror
        MySQL server
           + preparing web interface, this week new tag will be applied
      * researching EVE event display
           + geometry loaded
           + playing with displaying track information

Mark

      * data challenge running complete
      * FIU RFP issued

Javier

      * question on disposition of the solenoid after testing
      * question on mapping plan

Yi

      * helping Carl Zorn with rad-hardness tests

Elliott

      * in January or early spring furniture and computers will be bought
        for counting house

John

      * getting ready to stack the FCAL
