Time-of-Flight Prototype Work

Sasha showed plots from tests at FSU on the TOF prototype done by him and Chuck Bryant, their undergraduate student. They were using a XP2020 12-stage PMT's, a CAEN constant-fraction discriminator and an F1 TDC. They tried two different trigger counters, one 4 cm wide, the other 1 cm wide. With the narrow trigger counter they were able to achieve a resolution of about 150 ps on the time difference from the two ends of the counter.
