    keyword=Plane 1 Left TDCs Not Working - Bad Discriminator?

    Since returning from the down and starting production runs there are now problems in the HAND Plane 1 Left TDC Channels 8, 9, 10, 11, and 15 (counting from 0). These are from the same ribbon cable (Plane 1, Channels 0-15) that I moved to the second (bottom) output on the same discriminator during the down Tuesday afternoon (see HALog entry 274787). With the problem that I attempted to fix this afternoon and with the EDTM signal showing through but nothing else, I'm wondering if perhaps there might be something wrong with the discriminator (CAMAC Top Crate, Slot 5 looking at N1-1L through N1-16L)?
