Specification of SiPM to be measured, before and after radiation

  • Photon detection efficiency (PDE) = QuantumEfficiency * Geometrical Factor
  • Dark count vs overvoltage
  • Crosstalk vs overvoltage

Additional characterization

  • Cooling (reduction in dark counts, factor 2 for every 8-10° C ?)
  • Annealing, up to which temperature ?
