keyword=BB Dead TDC channel in dE planeYesterday we had turned on the Bigbite during the calibration runs,
and noticed that there is a problem with Right TDC channel #9. We
see no hits in that channel. We suspect that this must be a
hardware problem somewhere after the amplifiers, because we are
still able to see ADC spectra. Most probably I made a mistake, when
I was moving the TDC output signals on FAN-OUT modules from non-capacited
outputs to capacited outputs. We have decided to do this change because
at that time we were able to see 60Hz background noise in those signals.
