RICH LVL-1 status

RICH LVL-1 status. Dead channel (60% of total channel in Run-2) Large offset on the bias voltage 70% of dead channel has offset(>200mV) Variation of bias voltage of the trigger output Dead line on the back plane or connector (5%) Broken amp on the LVL-1 board (15%)

Calibrations of the ladders ?

Calibrations of the ladders ?. Before and after being assembled on a ladder, the modules are tested and characterized in terms of noise, dead channel s and pedestal offset. No systematic channel by channel calibration (for gain for example) is needed. Low voltage settings
