Compact solid-state detectors based on CVD single-crystal diamonds (SCD), configured in a p-type/intrinsic/Schottky-metal layered structure, are proposed for the detection of high-energy ions at the 15-MV tandem accelerator of the Southern National Laboratory of INFN in Catania. The spectroscopic response of two thin-film SCD detectors has been studied by varying the angle of incidence of a 27-77 MeV <sup>12</sup>C-scattered ion beam and a simple theoretical model is reported for the fit of the experimental curves of the collected energy vs. the angle of incidence. A rough estimation of the detector sensitive thickness and of the charge collection efficiency has thus been obtained.

Abstract
Compact solid-state detectors based on CVD single-crystal diamonds (SCD), configured in a p-type/intrinsic/Schottky-metal layered structure, are proposed for the detection of high-energy ions at the 15-MV tandem accelerator of the Southern National Laboratory of INFN in Catania. The spectroscopic response of two thin-film SCD detectors has been studied by varying the angle of incidence of a 27-77 MeV 12C-scattered ion beam and a simple theoretical model is reported for the fit of the experimental curves of the collected energy vs. the angle of incidence. A rough estimation of the detector sensitive thickness and of the charge collection efficiency has thus been obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
