对天然金刚石作为辐射探测器材料在宽温度范围内的性能进行了深入的研究。漂移速度和平均自由漂移时间已被确定在85 K和700 K之间的温度范围和电场高达60 KV/cm。在100 K - 400 K区间测量了产生电子-空穴对所需的平均能量和能量分辨率。本文还分析了金刚石探测器在较宽温度范围内的光谱特性。据发现，随着T接近500 K，极化现象开始，从而建立了检测器操作的温度上限。
A thorough investigation has been done about the behavior of natural diamond as a radiation detector material for a wide temperature range. Drift velocities and mean free drift time have been determined at temperatures ranging between 85 K and 700 K and with electric fields up to 60 KV/cm. Average energy required to create an electron-hole pair and energy resolution have been measured in the 100 K - 400 K interval. The spectroscopic features of diamond detectors have also been analyzed on a broad temperature interval. It was found that as T approaches 500 K polarization phenomena begin, thus establishing the upper temperature limit for the detector operation.
