  1. Sensor procurement status Mathieu Benoit

  2. Outline • Analysis of 150um-on-100um n-in-p assemblies • Status of submission to Advacam

  3. 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 fine • An 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
