The coincidence detector allows you to connect two GM-10 or GM-45 detectors and detect muons from cosmic rays.
How It WorksCosmic rays produce showers of radiation when they enter the atmosphere from outer space. These showers produce thousands of particles of radiation, so that two detectors, close to each other (or on top of each other) will both detect radiation at the same time. This process is called coincidence detection. (Normally, this would otherwise never happen under normal background radiation levels)
The coincidence detector looks at the output from each detector. When they both indicate detection of radiation at the exact same time, this is sent to the software an as event. This is called a coincidence detection.
It requires 12 volts DC from a supplied AC transformer power supply (overseas (non USA/Canada)
orders do not include the adapter, you must supply your own).
The Coincidence Box is $99.99.
