08.10.2011  06:33:28  event=180105  ***WARNING*** Error detected in APV 0, subevent 2. Event discarded, reset sent.
 

Permanent APV errors at several (all p-side, some n-side) APV chips after 180105 events, which could not be recovered by software resets. After restart of run, all APVs where alive again, hence hardware reset and I2C reconfiguration after 5 or 10 consecutive APV errors should be added to TUXDAQ software.

After APV errors occured, the cummulative bias current decrised from 78µA to 54µA. This effect can occures whenever the digital part of the APV is switched between idle and full operation. It seems that this is a thermal effect, caused by  the slightly higher power consumption of the digital part of the chips.

The beam is directly focused onto APV chip #2 of n-side, so that it hits the area underneath chip and cooling pipe.
On p-side this location is attached to chip #4, which currently can not be read out, hence we only get data for the n-side.
