W0011_I05 285 um p column pixels<br />Depletion at ~20 V<br />Breakdown at &gt;65 V<br />Threshold at 700 e or lower if possible<br />Equalisations at 65 V<br /> <br />10. Small angle scan<br />Bias Voltage: 25 V<br />Threshold: 1000e<br />One spill per angle<br />Angles -12, -10, -8, -5, -4, -3, -2, -1, 0, 1, 2, 3, 5, and 8

20. Bias scan for timing resolution<br />20 spills per step (~5 minutes per step)<br />lowest thl possible (800)<br />Angle: 0 degrees<br />Bias voltages: 2.5, 5, 10, 15, 20, 30, 40, 50, and 60 V

30. Angle scan for spatial resolution<br />10 spills per step (~2.5 minutes)<br />Bias voltage: 25 V (?)<br /><span style="background-color: transparent;">Threshold 800e<br />Angles: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 degrees</span>

40. Check for timing uniformity of DUT pixel matrix<br />For 60V bias<br />lowest thl possible (800?)<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 (middle same as point 20))

41. Check for timing uniformity of DUT pixel matrix<br />For 60V bias<br />lowest thl possible<br />same as 40, but now 1 continues measurement while moving the DUT

50. Angle scan at grazing angles<br />Bias: 60 V<br />5 spills per step<br />Real angles: 85(already done), 86, 87.5, 91.7, 92.5 (So actual angles in the VI should say 85-1.766, 86-1.766 etc.)

55. Grazing angle check<br />Bias: 60 V<br />1 spill<br />Real angle: 88.3

60. Bias scan for timing resolution<br />20 spills per step (~5 minutes per step)<br />Real angle: 88.3 degrees. (so actual angle in VI should say 88.3 - 1.766)<br />Bias voltages: 5, 10, 15, 20, 30, 40, 50, and 60 V

Redo 20.

70. 2D Scan for timing<br />5 spills per step<br />Threshold: 800 e<br />Angles: 5, 10 and 15<br />Bias voltages: 15, 30,and 60V 

71. 2D Scan for timing<br />5 spills per step<br />Threshold: 800 e<br />Angles: 5, 10, 15, and 20<br />Bias voltages: 15, 20, 30, 40, 50, and 60V

Maybe for later and to be finalised:

15. Threshold scan for timing resolution<br />20 spills per step (~5 minutes per step)<br />Bias voltage: 65 V<br />Angle: 0 degrees<br />Thresholds: 2000, 1750, 1500, 1250, 1000, 900, 800, 700, and lower if possible: 600, 500

50. Threshold scan for timing resolution<br />20 spills per step (~5 minutes per step)<br />Bias voltage: 65 V<br />Angle: 89 degrees<br />Thresholds: 1600, 1400, 1200, 1000, 900, 800, 700, and lower if possible: 650, 600, 550, 500
