Status of Time-of-Flight Work at FSU

Paul and Sasha reported on progress and plans.

  • They are assembling new trigger counters for the test set-up.
  • With the machine shop, Paul is working on a realistic light guide prototype. He showed us his working drawing. They will start by making one, then bend and test it.
  • Elliott will get a flash ADC to send to FSU. The P0 connector on their 64X crate is causes physical interference with the ADC and will have to be removed. (JLab people are dealing with the same issue on their 64X crates.)
  • FSU has purchased the CAEN constant fraction discriminator formerly on loan to them.

sasha plans measurements for time resolution, 600 ps, from leading edge discriminator, will try cfd

measure efficiency trigger, end left, end right use scalers

paul looking at undergraduate to help with measurments and software improvements

sascha questions different trigger types for tof detectors trigger electronics board monitoring will piggyback off calorimeter calibration system cosmic


chuck thinks there is room to start bending early

revisit schedule issue
