  1. SiPM measurement setup Laser collimator Adapter board NINO board Very first measurement: time difference betweenSiPM signal and Laser Sync(no optimization, T ambient) CAEN V1290 TDC 100 ps LSB σ = 364 ps

  2. Internal module basic ideas SiPM Array 25 x 50 mm128 3 x 3 mm2 pixels 128 channels ASIC(chip on board with cover) Pixellated 10 mm LYSOdetector read by 2 sidesfor DOI measurement (256 channels)

  3. Internal module advanced ideas Dual layer 5 mm LYSOdetector for better DOImeasurements (512 ch) Pitch of 1.5 or 2.0 mmcould be also archeivablefor better geometricalresolution PROBLEMS TO BE ADDRESSED ASIC: minimal implementation will have preamp-discriminators. In this scenario veryhigh density cabling will be necessary for off-detector signal processing. Our goal will be to design a final ASIC with all funcionalities (ADC + TDC) with minimal wiring (serial communication). MRI compatibility: studies must be performed to identify materials and methods formagnetic compatibility and RF shielding.

  4. 2011 Genova tasks Design and implement a discrete system for handling SiPM matrices: 1) SiPM support board for various SiPM vendors and types 2) Preamp-discriminator board (aka NINO board) 3) TDC + trigger logic + communication board All 3 boards will be stacked together using standardized connectors: Easyness for different trials: preamp board can be implemented with variousASIC version, permititng good testability Composizione gruppo genovese: Paolo Musico: 50 % Piero Calvini: 30 % Pasquale Ottonello: 30 % Giovanni Rottigni: 30 % Richiesta al Servizio di Elettronica per 3 mesi relativo allo sviluppo del sistema“discreto”.
