Minutes
Present:
- FSU: Sasha Ostrovidov
- JLab: Mark Ito (chair), Simon Taylor
Prototype Work
- The CAEN TDC arrived at FSU. It has a 25 ps least count. Sasha tested it with a pulser and got a resolution of 40 ps. A CAEN representative thinks that the TDC needs re-calibration. A procedure has been sent to Sasha; he will try it and see if performance improves.
- The problem reported last time with hits from channels with no signals connected was due to a faulty connector on the flat cable.
- The set-up (using the F1 TDC) is still infected with multiple-timing-peak disease.
Lightguides
- The FSU Physics machine shop can make light guides on their computer controlled milling machine. It should take about two hours per piece.
- The technique for bending has not been decided on. Some experiments have been done.
Contract
- The Advanced Procurement Plan being circulated for signatures.
