Spectrocam
Compact 64-channel SiPM Photodetector Module
Description
SpectroCam is a 64-channel system designed to readout silicon photo-multipliers (SiPM) for scientific instrumentation application. Spectrocam is a stack up of two boards. The front-end board is housing the 64-channel detector (Hamamatsu S13361-6050AE x4 or S14 series, can be adapted to other SiPM) on top side and readout ASICs (Citiroc1A x2) followed by a 15-bit ADC on the bottom side. The backend board embeds a FPGA (Cyclone V) for controlling the ASICs and HV voltage module provided in the kit. Spectrocam comes with open source firmware (Quartus) and open source software in C#. A CAEN high-voltage module is provided in the kit.
Provided software allows system calibration, ASIC programming and data acquisition with graphic user interface providing direct spectrum and flood map.
