  6. Bonn_3, 0°, configuration B 300V 200V 400V 600V 700V 2.10.2002 PixelWeek, CERN

  7. Bonn_3, 30°, configuration B 200V 300V 600V 400V 2.10.2002 PixelWeek, CERN

  8. Average charge collected • The average charge collected by Bonn_3 is in all cases 2 Ke less. 2.10.2002 PixelWeek, CERN

  9. Conclusion • The average charge collected with increasing bias as expected • The average charge is smaller for angle of 30°, but there was done one measurement with 400V and 10°, giving for this bias the best value (17Ke) • Why is there a hole in the middle of longer dimension? 2.10.2002 PixelWeek, CERN
