Time-of-Flight Status

Sasha reports that they have hired a student, Chuck Brandon, to work full time on measurements from the prototype. Again the immediate goals are:

  1. Repeat previous measurements with a constant fraction discriminator
  2. Use scalers to measure efficiency

They are still gathering equipment for these tests.

Start Counter Status

All of the main ingredients for testing this summer have arrived at FIU:

  1. fine-mesh pmt
  2. SiPM sample
  3. scintillator in various sizes
  4. full-scale light guide

Action Items

  1. Tim will find a copy of Chuck's drawing of the target area to show us.
  2. Elliott will ship a flash ADC to FSU for their test set-up.
  3. FIU will study different geometries for the start counter.
  4. Sasha will look at the bugs in his single-pi HDGeant study which uses the time-of-flight.
