论文摘要
单晶合成钻石传感器已被广泛用于辐射剂量法和束诊断。亮度边界的电子峰孔山脉山脉山脉的可预见的辐射环境需要彻底研究钻石对大辐射爆发的反应，尤其是对强烈的高能电子脉冲。在本文中，提出了一种两步的数值模拟方法（Sentaurus〜+〜ltspice）来探索该主题。通过TCAD-Sentaurus模拟钻石检测器的时间响应，而使用LTSpice考虑了电子电路的传输效果。在诱导信号的幅度和形状上，在探测器暴露于高能亚picsecond电子脉冲中，数值模拟的结果与初步实验数据之间观察到了良好的一致性。这种模拟组合是一种新型的方法，用于设计和优化粒子物理实验中的辐射和光束损失监测的钻石探测器。
Single-crystal synthetic diamond sensors have been widely used in radiation dosimetry and beam diagnostics. The foreseen harsh radiation environment in electron-positron colliders at the luminosity frontier requires a thorough investigation of diamond's response to large radiation burst, in particular, to intense high-energy electron pulses. In this article, a two-step numerical simulation approach (Sentaurus~+~LTspice) is proposed to explore this topic. Time response of the diamond detector is simulated via TCAD-Sentaurus while the transmission effect of the electronic circuit is taken into account using LTspice. Good agreement is observed between results of the numerical simulation and preliminary experimental data from detector's exposure to high-energy sub-picosecond electron pulses, on both the amplitude and the shape of the induced signals. This simulation combination is a novel approach to designing and optimising diamond detectors for radiation and beam loss monitoring in particle physics experiments.
