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:
- Repeat previous measurements with a constant fraction discriminator
- 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:
- fine-mesh pmt
- SiPM sample
- scintillator in various sizes
- full-scale light guide
Action Items
- Tim will find a copy of Chuck's drawing of the target area to show us.
- Elliott will ship a flash ADC to FSU for their test set-up.
- FIU will study different geometries for the start counter.
- Sasha will look at the bugs in his single-pi HDGeant study which uses the time-of-flight.
