标题： Physical Design and Monte Carlo Simulations of a Space Radiation Detector onboard the SJ-10 satellite

摘要： 搭载在SJ-10卫星上的辐射基因盒（RGB）是一种携带小鼠和果蝇细胞的装置，用于确定空间辐射环境的生物效应。 不同放射源的屏蔽通量被计算出来，并通过A-150组织等效塑料获得了伽马射线、电子、质子和α粒子在组织中的线性能量转移。 然后，设计了一种概念模型的空间辐射仪器，该仪器使用三个半导体子探测器来推导RGB的带电和非带电辐射环境。 在从蒙特卡罗方法推导出的算法中，三个子探测器中的能量沉积被分为十五个通道（bins）。 此外，通过蒙特卡罗模拟验证了该概念仪器的物理可行性。 显示英文摘要

摘要： A radiation gene box (RGB) onboard the SJ-10 satellite is a device carrying mice and drosophila cells to determine the biological effects of space radiation environment. The shielded fluxes of different radioactive sources were calculated and the linear energy transfers of gamma-rays, electrons, protons and alpha-particles in tissue were acquired using A-150 tissue-equivalent plastic. Then, a conceptual model of a space radiation instrument employing three semiconductor sub-detectors for deriving the charged and uncharged radiation environment of the RGB was designed. The energy depositions in the three sub-detectors were classified into fifteen channels (bins) in an algorithm derived from the Monte Carlo method. The physical feasibility of the conceptual instrument was also verified by Monte Carlo simulations.
