Previous meeting: Friday, April 12, 2013 11:00am EST


  1. How many people will come in October from each group?
  2. Plans and goals
    1. Review the goal for this first run: test several quartz/lightguide/PMT prototypes with emphasis on pulse height spectra and sensitivity to backgrounds in the light guides
    2. Manitoba and UMass prototypes (number of prototypes and concepts)
    3. Anything else besides the above?
  3. Preparations at Mainz
    1. Basic components: test table, trigger scintillators, DAQ system, analysis scripts….
    2. Envision a modular setup which is self-aligned but will facilitate quick swap-in/out of various prototypes. Get input on this. Frank, Sebastian and I will flesh this out during the week.
    3. Formulation of a run plan to accomplish both MOLLER and P2 goals during this week
  4. time of next Monday's phone meeting


Attending: Seamus, Rupesh, Juliette, Paul, Dustin, Michael, Frank, KK, Dominic, Katherine, Sebastian

  1. How many people will be coming in October?
    1. UMass - Seamus, Jon Wexler (KK will be there the previous; help with prep)
    2. U of M - Peiqing, Michael, Juliette near end (MENU conference - would be useful)?
    3. Syracuse - Paul (teaching)?
    4. Idaho State - Dustin can go for the whole time
    5. Mainz - Dominic, Katerine, Sebastian?
    6. W&M - Valerie?

  2. Plans and goals
    1. Review the goals - test pulse heights on prototypes
      1. different positions, angles on quartz
      2. different positions, angles on light guides
      3. cross-talk tests
    2. Prototypes
      1. U of M
        1. at least 3 pieces of quartz (up to 6, with 3 higher priorities)
        2. at least 2 different types of tubes
        3. different light guide materials (reflectivities)/lengths
        4. PMT, quartz mount on each assembly so we can switch it out
      2. UMass
        1. several spare pieces of PREX dimension quartz (cut perp. and 45 degrees)
        2. light guides very important
    3. New item - Ordering materials
      1. PMTs and quartz
      2. Michael is talking to companies for both

  3. Preparations at Mainz
    1. Basic components
      1. Table
      2. trigger scintillators - wide variety are available (fingers, wide)
      3. DAQ system - Caen ADCs, need to bring?
        1. U of M - waveform digitizer and pulse height ADCS V1720 (crate controller?)
        2. UMass C1205
        3. Frank had listed DAQ components - don't need to bring them - KK will check
      4. Analysis scripts
        1. Dominic and Katherine will be there
        2. Seamus and Rupesh should come early to become familiar
    2. New item - beam quality
      1. motion, charge, energy control
      2. between 200 and 800 MeV
      3. going through air -> How much? Where is the vacuum window? What is window made of?
    3. Modular setup (next week)
    4. Run plan (next week)

  4. Meet again - same time next week
