Single photon gain/noise for old and new settings (Zongde)

ASIC3


ASIC2


Cross-talk correction for single photon under mask column-wise (Zongde)


Dark pixel common mode correction


Dark pixel but with low flux photon leakage


Pedestal and offsets at transition point for new settings for both temperatures (Bhavna/Philip) 



TID lab Charge injection tests (Alex&Xavier)

Charge injection with variable number of columns, while monitoring a control pixel (non-injected), in auto gain. Injected columns are: 14 - 374, 86 - 374, 158 - 374, 230 - 374 and 302 - 374. The cross-talk magnitude increases with the amount of charge injected:


Same as above but in HDR (high dynamic range) auto gain:
CompTH_ePixM = 24
Precharge_DAC_ePixM = 50
RefinN = 7
RefinP = 7

The apparent step-function point at around 400 pulser value corresponds to gain switching point in injected pixels. Now the question is what causes this jump in non-injected pixels
