Polycrystalline chemical vapour deposited (CVD) diamond film is an interesting material for neutron detection and dosimetry. However, the use of CVD diamond detectors is still limited by the low-level signal pulse produced because of the high energy required to produce an electron-hole pair in diamond (13.2 eV) and by the reduced charge collection efficiency owing to several types of traps for electrons and holes in CVD films. A new type of CVD diamond detector with high gain (HG) contacts was produced as part of the collaboration between the ENEA Fusion Division and the Faculty of Engineering of Rome 'Tor Vergata' University. In this paper the performance of the HG CVD diamond detector is presented and possible applications of CVD diamond detectors to neutron dosimetry are also discussed.
多晶化学气相沉积（CVD）金刚石薄膜是一种用于中子探测和剂量测定的有趣材料。然而，CVD金刚石探测器的使用仍受到限制，这是由于在金刚石中产生电子-空穴对所需的能量较高（13.2电子伏特）导致产生的低电平信号脉冲，以及由于CVD薄膜中存在几种电子和空穴陷阱而导致的电荷收集效率降低。作为意大利国家新技术、能源和可持续经济发展署（ENEA）聚变部门与罗马第二大学工程学院合作的一部分，制造了一种新型的具有高增益（HG）触点的CVD金刚石探测器。本文介绍了HG CVD金刚石探测器的性能，并讨论了CVD金刚石探测器在中子剂量测定中的可能应用。
