keyword=S2m Cabling, Patch Panel, ADC and TDC Maps
The cabling for S2m on the left HRS has been completed. Youcai and I
tested the signal and HV cables prior to re-installing the cables on the
detector stack. The ADC cables and path through the patch panel was
tested with a pulser. We found all the cables to be in good condition,
but we also found we could not get a signal through the tenth channel
of the Helga patch panel. We moved S2m R6 cable from this channel to an
available channel in the Betty patch panel B13.
The following provides the patch panel, ADC and TDC channel maps for S2m.
Note that the Helga patch panel is Ingrid on the lower platform beside
the fastbus crates:
