Time-of-Flight Status
Sasha reports that he has continued to work with the Phillips 715 constant fraction discriminator. He is using a 10 cm cable for the delay. Currently he is having problems with cross-talk; signals in one channel produce signals in a neighboring channel. This is giving spurious peaks in his timing spectra. These tests have been done with a pulser. Nonetheless he is getting about 150 ps timing resolution from the TOF prototype with this discriminator.
Beni suggested trying a 4 ns delay cable.
