  15. SiPMs - Multipixel Geiger Mode Photodiodes 1156 fotodiod na ploše 1.1 x 1.1 mm2 J. Žáček Detektory

  16. SiPMs for calorimetry ITEP • Multipixel Geiger Mode Photodiodes • Gain 106, bias ~ 50 V, size 1 mm2 • Insensitive to magnetic fields 3x3 cm scintillator tile with WLS fibre Auto-calibrating but non-linear 1156 pixels with individual quenching resistor on common substrate J. Žáček Detektory

  17. Readout and calibration • Readout: follow integrated apporach for ECAL and HCAL • Synergies in ASIC development • Standardized system downstream • Calibration: use MIP scale • inter-calibration and long-term variations • Monitoring: auto-calibration • SiPM gain variations directly observable (~2%/K) • Also needed for non-linearity corrections J. Žáček Detektory

  18. Tile HCAL testbeam prototype • 1 cubic metre • 38 layers, 2cm steel plates • 8000 tiles with SiPMs • Electronics based on CALICE ECAL design, common back-end and DAQ Tile sizes optimized for cost reasons J. Žáček Detektory
