Equipment
The SiPM-2000 is a single-board MCA that includes a precision SiPM voltage supply.
It is powered through USB and uses and embedded FPGA plus a 32-bit ARM M0+ processor and SoC for acquiring histograms, computing count rates and alarms, even providing list mode operation and performing pulse shape discrimination. It can be a complete portal monitor appliance which alarms on radioactive materials passing by in a vehicle.
