Abstract :
This paper reports about the influence of working temperature on the spectrometric and time dependent performances of single crystal diamond detectors (SCD) operating at temperature up to 200°C and irradiated with alpha particles. Two different types of SCD detectors were studied: a) SCD of commercial type; b) SCD produced at Rome “Tor Vergata” University and characterised by a layered structure. The first measurement of the response functions vs. temperature of the commercial SCD detector irradiated with 14 MeV neutrons and heated up to 140°C is also reported. The measurements pointed out the superior performances of diamond respect to other detectors (e.g. silicon) when operated at high temperature, however the present work also pointed out that a diamond detector assembled to operate at room temperature can suffer of mechanical and electrical stress. The results indicate that with a proper design diamond detectors can be suitable for operation at high temperature.
