Cluster Size 11 Too many single pixel clusters. The resolution can not be as good as what was claimed. Thresholds are not the same for different telescope planes. Threshold needs to be further reduced. Gain, threshold calibrations are not available yet. Number of Pixels in a Cluster Diamond DUT

Charge Distribution 12 Gain calibration need more work. Gain for diamond seems wrong. This just give you an idea on how they work. Charge (Ke) Diamond DUT

Form Raw Tracks 15 Number of Raw tracksNumber of Hits Per Track Track window is quite lose for two reasons: Detectors are not aligned yet. Want to include interaction tracks.

Summary  Different radiation hard sensors are tested: sCVD diamond, MCZ, 3D.  We are more interested in the diamond detector. Properties extracted from this test beam will be important inputs to our upgrade simulation.  Get familiar with the CAPTAN system, get offline analysis package ready. We may have our own detector tested with the system in near future. 16

PSI Signal and Addressing 17 For each hit pixel, the readout chip produces a signal at six levels. The first five encode the pixel address. The 6 th represents the analog signal from the pixel. The first two encode the double column address. The next three encode the pixel address in that double column. Most significant bit for the double column address (C0) Least significant bit for the double column address (C0) Least significant bit for the pixel address in the double column (A0) Most significant bit for pixel address in the double column (A2) A1 Analog signal from the pixel (data) One pixel hit
