Nuclear environments as well as areas where security is paramount (i.e. airports, naval ports, etc.) need miniaturized sensitive detectors able to measure and recognize the kind and energy of radiation potentially dangerous for human health (alpha and beta particles, fast neutrons).
The CVD diamond-based spectrometers we develop, operate at room-temperature (commercial detectors need to be cooled to minimize electronic noise) and have a charge collection efficiency close to 100%, coherent with a very high sensitivity.
The energy resolution is <1%, that is a value able to allow determination of the impinging radiation energy and consequently of the radioisotope emitting it.
Irradiation tests with fast neutrons, in collaboration with CNR-IFP, demonstrated a high operating time and sensitivity both for single pixels and for detector matrixes.
ISM has a commercial and development agreement with CAEN Spa
