keyword=HAND N1-13L EDTM Signal/TDC ProblemsLooking at one of the cosmics runs from today I noticed that N1-13L was
not showing an EDTM signal like all of the other TDC channels (Figure 1
below). I went down in to the Hall and unplugged and re-plugged the
cables and using the second output on the discriminator (CAMAC Top Crate,
Slot 5) while triggering on the EDTM signal I was able to see the signal
coming from the discriminator. I took a cosmics run (#21371) but the
signal was still not showing up on the histograms. I then took the ribbon
cable out of the top output on the discriminator and put it into the
secondary (bottom) output and took cosmics run #21372. This seems to have
fixed the problem (Figure 2 below).
