PMT-2000

Contains an MCA and plugs directly on to a photo-multiplier tube (PMT)

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 even be a complete portal monitor appliance which alarms on radioactive materials passing by in a vehicle.
