SiPM measurement setup

NINO board

Adapter board

Very first measurement:time difference betweenSiPM signal and Laser Sync(no optimization, T ambient)CAEN V1290 TDC 100 ps LSBσ = 364 ps

Laser collimator

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)

Internal module basic ideas

Internal module advanced ideas

Dual layer 5 mm LYSOdetector for better DOImeasurements (512 ch)

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) withminimal wiring (serial communication).

MRI compatibility: studies must be performed to identify materials and methods formagnetic compatibility and RF shielding.

Pitch of 1.5 or 2.0 mmcould be also archeivablefor better geometricalresolution

2011 Genova tasks

Design and implement a discrete system for handling SiPM matrices:1) SiPM support board for various SiPM vendors and types2) 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
