A 2.4-GHz wireless alpha-ray sensor for remote monitoring and spectroscopy

Wireless alpha-ray device has been designed, realized and tested in operation. The first prototype is a battery-supplied system with a compact package and wireless communication capability. One of the more attractive features is its ability to operate in a star network (single point-to-multipoint). The sensor records the arrival time of the alpha particles and the spectrum of the produced charge; it transmits this information in regular time intervals or upon request to the base station. The overall system has a compact package suitable for remote alpha-ray spectroscopy.
