W0039_G11 50 um n-in-p<br />Depletion at -20 V<br />Breakdown at -120 V<br />Threshold at 700 e<br />Equalisations at -20, -40, -60, and -100 Volts<br /> <br />10. Small angle scan<br />Bias Voltage: -100 V<br />One spill per angle<br />Angles -21, -13 -8, -5, -3, -2, -1, 0, 1, 2, 3, 5, 8, 13, and 21

15. Threshold scan for timing resolution<br />20 spills per step (~5 minutes per step)<br />Bias voltage: -100 V<br />Angles: 0 and 89 degrees. (perpendicular to get all charge in a single pixel and grazing to probe drift distance)<br />Thresholds: 1000, 900, 800, 700, and lower if possible: 650, 600, 550, 500

20. Bias scan for timing resolution<br />20 spills per step (~5 minutes per step)<br />Angles: 0 and 89 degrees. (perpendicular to get all charge in a single pixel and grazing to probe drift distance)<br />Bias voltages: 5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, and 100 V

25. Threshold scan for spatial resolution<br />10 spills per step (~2.5 minutes)<br />Bias voltage: 25 V (?)<br />Angle: 45 degrees<br />Thresholds: 1000, 900, 800, 700, and lower if possible: 650, 600, 550, 500

30. Angle scan for spatial resolution<br />10 spills per step (~2.5 minutes)<br />Bias voltage: 25 V (?)<br />Angles: 20, 25, 30, 35, 38, 40, 42, 44, 46, 48, 50, 52, 55, 60, and 65 degrees

40. Check for timing uniformity of DUT pixel matrix<br />For 20, 60, 100V bias?<br />lowest thl possible (700?)<br />20 spills per position (~5 minutes per step)<br />Depending on beam spot size, scan complete DUT (e.g. 1 around each corner and 1 in middle for big spot size)

50. Grazing angle

60. Tp calibration (sunday)
