报道了在罗马“Tor Vergata”大学实验室采用微波化学气相沉积技术在高压高温单晶衬底上制备的同外延金刚石薄膜的生长条件和检测性能。当用5.5 MeV的Am241 α-粒子照射该器件时，能量分辨率低至1.1%。本文还报道了电荷收集效率和能量分辨率随外加电压的变化规律。在两条曲线中观察到一个明显的饱和平台。用14.8 MeV中子辐照的初步结果显示，C12(n,α0)Be9反应峰分离良好。
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 Am241 α-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 C12(n,α0)Be9 reaction peak.
