Minimalistic board that allows you to quickly and easily utilize a silicon photomultiplier (SiPM) within your other projects. Supports a range of input voltages, has a digital (TTL) pulse output for the registered counts and a direct output for the SiPM pulses for easy expansion.

With its small size of only 10 x 2.5 cm this board features everything you need to get running with a simple scintillation counter. The SiPM power supply is built for any SiPM using 28 - 34 Volts. The output signal is fed into a comparator that outputs TTL pulses for every detected gamma-ray.
 
The Mini SiD is a stripped down and much smaller version of the Open Gamma Detector. It can be used with any input voltage from 3.2 - 5.5 Volts. The outputs include a raw pulse pin and a single TTL out that can be used for time-over-threshold applications!

By connecting the TTL "INT" pin to an interrupt pin of a microcontroller, you instantly have yourself a simple, but very powerful scintillation counter. A scintillation counter is a much more powerful alternative to a geiger counter and using a SiPM you don't even need a high voltage. It's as easy as that! Of course, you can always use the raw pulses from the "SIG" pin and connect it to a MCA to do some gamma spectroscopy.

Example project: Scintillation Counter

A great project utilizing the Mini SiD is building a scintillation counter, which can be much more powerful than a geiger counter while being safer to use, because of the relatively low voltages.

One great example build has been done by RD-Gamma, who built one such device using a russian scintillator and a Broadcom AFBR SiPM.
