Run Conditions

  • Laser and one PS electronic board

  • 3 SiPM's bias groups per run

Laser Amp = 11.55 + diffuser + NDF 2.0, Rate = 200 Hz

One fADC-250 board, slot 5

based on 3 boards:

1 LV - Wiener OMPV 8008 Slot 9
2 Bias - I-SEG EHSF 201 Slots 2,3 (A)
Runs condition and results

Single Pixel Spectrum

  • single pixel spectrum, SiPM 142

  • A23, A24, A25 bias group

SiPM's gain distribution

  • All SiPMs gain

  • Average gain by group

SiPM Noise

  • run 96: T=27.18^{{0}}C

Laser Amp = 11.55 + diffuser + NDF 2.0, Rate = 200 Hz

SiPM Amplitude = 35 mV
