The development and calibration of a measurement system designed for assessing the performance of the avalanche photodiodes (APDs) used in the Compton scattering polarimeter of the CUSP project is discussed in this work. The designed system is able to characterize the APD gain GAPD and energy resolution across a wide range of temperatures (from -20 °C to +60 °C) and bias voltages Vbias (from 260 V to 410 V). The primary goal was to experimentally determine the GAPD dependence on the and Vbias in order to establish a strategy for stabilizing GAPD by compensating for fluctuations, acting on Vbias. The results demonstrate the system capability to accurately characterize APD behavior and develop feedback mechanisms to ensure its stable operation. This work provides a robust framework for calibrating APDs for space environments. It is essential for the successful implementation of spaceborne polarimeters such as the Compton scattering polarimeter foreseen aboard the CUbeSat Solar Polarimeter (CUSP) mission under development to perform solar flare X-ray polarimetry.
本文讨论了一种测量系统的开发与校准，该系统旨在评估用于CUSP项目康普顿散射偏振计中的雪崩光电二极管（APD）的性能。所设计的系统能够在很宽的温度范围（从-20°C到+60°C）和偏置电压Vbias（从260V到410V）下对APD增益GAPD和能量分辨率进行表征。主要目标是通过实验确定GAPD对温度和Vbias的依赖性，以便制定一种策略，通过作用于Vbias来补偿温度波动，从而稳定GAPD。结果表明该系统有能力准确地表征APD行为，并开发反馈机制以确保其稳定运行。这项工作为校准用于空间环境的APD提供了一个强大的框架。对于正在开发的CUbeSat太阳偏振计（CUSP）任务中设想的诸如康普顿散射偏振计等星载偏振计成功实施太阳耀斑X射线偏振测量至关重要。
