Settings:

• Vdd (on hybrid) = 4.00 V.
• Vcc (on hybrid) = 3.50 V.
• Edge detection circuitry disabled.
• Compression mode Level (X1X).
• Bias Current = 220 uA.
• Shaper Current = 31.2 uA.
• Vbias = 100 V.
• Temp (on cooling block) = 28 °C

Comments:

• We have observed that the timing for maximum effciency (Strobe Delay Setting) depends on the input charge (plot). We have used a different Strobe Delay Setting for each input charge:

  Input Charge (fC)	1.0	1.5	2.0	3.0	4.0
  Strobe Delay Setting	10	14	17	20	22

• We have reported the input noise value at 2fC, but since the input noise depends on the input charge different values could have been showed.

• We have observed a big increase in the detector current on last 10 days. Current has increased from 2uA to 20 uA for Vbias=100V. It could be a consequence of module manipulation, that could explain the bad behaviour of E13.
