Methodology
After wire-bonding, chip is powered, sensor biased at 40V
Chip threshold equalization is performed twice, mask pattern is written to disk
First equalisation lead to weird masked pixel pattern (
checkboard
)Second equalization works usually fineAn image of a Sr90 source is taken with Exposure time of 30s (every pixel should see some energy deposition)A simple algorithm count how many pixel see no or too little signal (<20% of neighbors) and compare to mask Slide4
