1. JLAB discriminator board prototype was tested by Sergey P., latest test was with triangle pulse, all results obtained with rectangular pulse were confirmed, although threshold slope changed slightly: 0.235 (triangle) and 0.263(rectangular), Ben will check it, it must be exactly 0.25. Passive splitters were used. Temperature test still to be done. Board will go to Ben for more tests and changes as we discussed September 30. When ready, will order 5 boards. If Sergey Kuleshov's people will be involved in testing and production, we'd recommend to produce test board to run tests automatically. We will discuss it by email and personally when people from that group will be here next year.
