Hall B Discriminator
Ben described recent work on a discriminator developed for Hall B. Fernando says it fits Hall D needs perfectly, and is much cheaper and better than the CAEN V895 discriminators we were planning to use.
- 16-channel dual-threshold, non-updating, 0 -> -1V.
- Includes many scalers.
- Standard VME mount.
- Very similar to CAEN V895 but about one half the cost.
- 200 needed for CLAS12, about 200 for Hall D.
- Very low cross-talk and noise.
- Will have 5 for Hall B and 2 for Hall D fairly soon for testing.
- See Ben's talk above for many details.
