摘要:

本文介绍了一种用于航天器的新型高分辨率粒子辐射监测器(HMRM)的设计和初步标定结果。HMRM设备包括封闭在钛屏蔽中的有源像素传感器的伸缩配置,估计总质量为52 g,体积为15 cm $^3$。该监测器旨在提供实时剂量测定和对通量高达10 $^8$ cm $^{-2}$ s $^{-1}$(全向)的高能带电粒子的识别。用如此小的仪器实现这一能力可以为空间辐射探测开辟新的前景。

英文摘要:

We present the design and preliminary calibration results of a novel highly miniaturised particle radiation monitor (HMRM) for spacecraft use. The HMRM device comprises a telescopic configuration of active pixel sensors enclosed in a titanium shield, with an estimated total mass of 52 g and volume of 15 cm$^3$. The monitor is intended to provide real-time dosimetry and identification of energetic charged particles in fluxes of up to 10$^8$ cm$^{-2}$ s$^{-1}$ (omnidirectional). Achieving this capability with such a small instrument could open new prospects for radiation detection in space.
