摘要：

The growth conditions and the detection properties of a homoepitaxial diamond film, deposited in Roma "Tor Vergata" University Laboratories by microwave chemical vapor deposition on a high-pressure high-temperature single-crystal substrate are reported. An energy resolution as low as 1.1% was achieved when irradiating the device with 5.5 MeV Am-241 alpha-particles. The dependence of the charge collection efficiency and the energy resolution on the applied voltage are reported as well. A clear saturation plateau was observed in both curves. Preliminary results with 14.8 MeV neutron irradiation are reported, showing a well separated C-12(n,alpha(0))Be-9 reaction peak. (c) 2005 American Institute of Physics.
