Planning for TB'16

Thoughts about sensors for future tests

ANALYSIS

  1. High number of clusters on the telescope was observed when no clusters were detected on DUT and CMSPixRef. This can be related to the high DAQ rate which was observed during the beam time. Such events should be excluded or maybe used for telescope alignment.
  2. Clustering efficiency, i.e. the ratio between the number of events when clusters were detected on telescope as well as on the DUT and CMSPIxRef. with respect to all events from the considered data sample, is ~2%/199 out of 10000 events/ (run000012.dat, run000013.ped, run000224.raw, sample@-1000V, 0 deg. inclination, no annealing, -30 deg. C) - too low! E.g. the efficiency for the June's data was up to 30%. This can be related to used TDC cuts (from 25 to 45 ns - these cuts were set as default in the steering-tamplate, so wasn't any reason to use them).
