    Yi Qiang, Sascha Somov, Elton Smith, Simon Taylor, Elliott Wolin, Beni

Eugene

      * Voluntary Separation Program: all should be aware of the offer
      * Lab-Directed R&D
           + right now the group is busy
           + in general DOE has no independent fund for R&D at JLab
           + money will be taken from operations
           + projects that run in Hall, can qualify
      * consolidate space--Elton: transportainer of stuff from the magnets?
        Elliott: Tom Carstens would know about it
      * Lehman review
           + will be one in November
           + address re-baselining of the project
           + unclear: big yearly review or not
           + want to keep contingency at 20% of remaining work
      * PAC
           + one proposal conditionally approved, one deferred
           + letters of intent: one got encouragement, pion polarizability
      * we are encouraged lab-wide to push procurements forward into this
        fiscal year, plan even for beginning of next fiscal year
      * some funds from DOPS left at end of this year, reasonable requests
        entertained
           + Elton: scintillators with phototubes

Beni

      * next week: meeting for gas system, will develop inventory list
      * DAQ system for Linux almost ready to run
      * after grounding of FDC package #3, move into EEL for testing
      * playing with fsgen to create e^+e^- pairs to study inverse DVCS

Hovanes

      * looking at things to buy
           + scaler modules
           + FPGA modules
           + serial console servers
      * barcode scanner not working well, ask for another one
      * portable NIM crate and portable VME crate would be nice to have

Elton

      * BCAL work mainly
      * Zisis and two students coming next week
      * ESB work: Tara Bogart working on monitoring, DAQ is running
      * light guides: first shipment scheduled for this week, but a week
        behind schedule
      * new boards should arrive pretty soon
      * student working with Jim Fochtman making box to test read-out
        modules

Bert

      * there will be an Emergency Management Self-Assessment next week
           + safety wardens and managers may be quizzed
           + anyone in area can be questioned by a reviewer
      * late this afternoon: put your dosimeter in the rack for change-out
           + Elton: rack near Hall D? David: Becky Mosbrucker says not for
             two years
      * F117, two weeks ago, concern in passageway about solvent smell
           + Medical Director asked for air sampling, done last Tuesday
           + waiting for results to come back

Yi

      * Ben Laurent[?] looking at SiPM production data taken by Bobby,
        re-tested some samples, samples consistent with Hamamatsu data,
        only one outlier out of about 1000 devices.
      * next ask Ben for cross-talk and after-pulsing measurements to
        optimize bias voltage
      * working on a simulation environment for HDRICH detector and
        simulation of J/$psi;
      * Elton: did inventory, lost 4 SiPM's, spare SiPM's might be needed
           + ordered 4k units, enough for 50 modules, will have 48
           + extras are scattered
           + Will Brooks: Hamamatsu will allow order at previous price,
             $565 each, $600 including testing

Sascha

      * met with Dan Sober and Franz Klein on strategy for fixed array
           + need to decide on counter size, light guides, and mounting
             structure
           + Dan running transport program, finds agreement with Sascha's
             simulation
           + tagging efficiency for amorphous radiation: Dan is studying
             it, sees degradation at endpoint energy, can move quadrupole
           + Dan will review counter sizes and positions for fixed array
           + PMT specifications: not much progress, Fernando Barbosa
             willing to help with electronics
           + Sasha will outline SOW for fabrication and testing of fixed
             array, will assemble at CUA
      * discussions with Richard: microscope and pair spect. will use 50
        micron SiPM
      * last week Hamamatsu returned call, will get quotes from them this
        week
           + will use 3x3 mm sensor for pair spectrometer
           + may add more sensors in the future, e. g., 100-micron devices
             for start counter
           + 900 to 1000 sensors
      * also asked for quote for low granularity pair spectrometer counter
        PMTs, will need 18 of them
      * Fernando has ideas on how to couple WLS and sensors for pair
        spectrometer
      * Ivan Tolstukhin will come at beginning of August
      * DAQ for BCAL: 32-bit vs. 64-bit issue being wrestled with
      * also working on simulation for eta rare decays

David

      * working with students on:
           + mini-BCAL
           + ROOTSpy
      * post-doc from UMass was here, got him going on pion polarization
        stuff
      * got an abstract in for Chiral Dynamics 2012 on pion polarization

Simon

      * working on diagnostic histograms for b1pi analysis
      * standardizing parametrization for tracks in final object, including
        the 5x5 covariance matrix
      * studying running with 1200 A vs. 1500 A magnet current
      * improving algorithm for determining vertex

Mark

      * discussions underway on the scope of the data challenge
      * start counter readout boards being populated: they look nice

Lubomir

      * dehumidifier at Blue Crab went out over weekend, some spare parts
        were exposed
      * 4th package installed a week ago, found one cathode off by 15
        degrees
           + split the package in half and re-assembled successfully
           + continue today with testing of 4th pafkage, finish by Thursday
      * beginning of next week: refurbish 2nd package
           + 2nd package back at blue crab now
      * testing of spare parts:
           + 1st wire frame did not work
           + 2nd OK
           + 3rd having problems, has HV caps that were not replaced,
             covered with Humiseal now
      * according to schedule, finish production end of year
           + extra tasks not originally anticipated: build some wire
             frames, refurbish packages 1 and 2

Elliott

      * working on Fastrack schedule for solenoid test
           + talked to everyone except Tom Carstens
           + Tom and Tim Whitlatch are discussing how to transfer Tom's MS
             Project schedule
           + critical path ends up going through cryo installation, though
             details are missing
           + manpower: Josh Ballard and Mark Stevens were over subscribed,
             juggling things so that they are OK
      * Dave Abbott working on raw data tape stuff, should be done by end
        of July
      * helping Josh with temperature, humidity read-out
