When X-rays and gamma rays irradiate a vacuum Compton detector (VCD), photoelectrons and Compton electrons are generated on the cavity surface, resulting in a strong internal electromagnetic pulse (IEMP) in the cavity. To quantify the characteristics of the IEMP interference on VCD response, an electromagnetic interference-coupling model for a VCD was established with computer simulation technology particle studio (CST PS). The accuracy of the model was verified under pulsed gamma conditions. The characteristics of electromagnetic interference were studied by simulation and experimental methods under a 50 ps pulsewidth electron accelerator. The results are in good agreement in time and frequency. The effects of absorbing materials to strengthen anti-electromagnetic interference of the VCD were simulated using the model. The possible sources of interference signals were discussed as well. The coupling model presented in this article provides an efficient and accurate tool for the anti-electromagnetic interference design of VCDs under pulsed X-rays, gamma ray, and electron radiation.
当 X 射线和伽马射线照射真空康普顿探测器(VCD)时,腔体表面会产生光电子和康普顿电子,从而在腔体中产生强烈的内部电磁脉冲(IEMP)。为了量化内电磁脉冲对 VCD 响应的干扰特性,利用计算机模拟技术粒子工作室(CST PS)建立了 VCD 的电磁干扰耦合模型。在脉冲伽马条件下验证了模型的准确性。在 50 ps 脉宽的电子加速器下,通过模拟和实验方法研究了电磁干扰的特性。结果在时间和频率上都非常吻合。利用模型模拟了吸收材料对加强 VCD 抗电磁干扰的影响。同时还讨论了干扰信号的可能来源。本文介绍的耦合模型为脉冲 X 射线、伽马射线和电子辐射下的 VCD 抗电磁干扰设计提供了一个有效而精确的工具。

This work presents the impact of heavy ion irradiation on vertical-diffused metal-oxide-semiconductor field-effect transistors (VDMOSFETs), particularly focusing on the ionization and displacement damage pivotal for the operation of devices in space environments. We conducted experiments using irradiation with chlorine, silicon, fluorine, and oxygen ions. Our analysis involves calculating the linear energy transfer (LET) and nonionizing energy loss (NIEL) for various ion incidences, followed by determining the ionizing absorbed dose ( $D _{mathrm {i}}$
