keyword=HAND HV Change, TDC Ribbon Check, ADC Filter added
The following was done during the access:
The TDC ribbon cable coming from the discriminator in the bottom crate, slot 02 (for channels N2-3L through N2-18L) was unplugged and plugged back in. This seems to have fixed the missing TDC histogram (see below).
An ADC filter was added to the ADC ribbon cable for channels N1-17R through N2-2R.
HV was changed by the following:
Channel N4-2L (bbps1:2001, slot L9.1) is now set to -1450V (it used to be -1425V)
Channel N4-3L (bbps1:2001, slot L9.2) is now set to -1500V (it used to be -1475V)
This was done to see some more structure that was missing from these channels.
