Research Abstract

Growth condition of CVD diamond single crystals were optimized. Radiation detectors were fabricated form the grown CVD diamonds; then induced charge collection distribution measurement for the detectors were carried out by use of alpha particles. Charge collection efficiency of 100 % and 97 %, μτ values of 1×10-4 and 9.6×10-6 cm2/V for holes and electrons were achieved by one of the best detectors. In addition, energy resolution of 3.5 % at a peak caused by the 12C(n, alpha)9Be reactions were obtained in response function measurement for 14 MeV neutrons. Fast time resolution of 350 ps was also achieved for 8 GeV electron beams.
