COMCUBE-S CubeSat Swarm 型Gamma射线暴极化测量：设计与性能仿真
摘要
COMCUBE-S（COMCUBE-S (Compton Telescope CubeSat Swarm)）是一项旨在理解Gamma射线暴（GRB）超相对论喷流辐射机制的计划任务。该任务由16U CubeSat组成，搭载最先进的康普顿极化仪和铋锗氧化物（BGO）光谱仪，用于对GRB prompt 辐射进行计时、光谱和极化测量。该任务目前处于欧洲空间 agency 准备进行轨道示范的可行性研究阶段（Phase A）。本文呈现用于优化微卫星星座的设计和操作概念，以及估计该任务在GRB探测率和极化方面的性能的仿真工作。我们使用MEGAlib软件模拟gamma射线仪器的响应函数，结合对低轨道背景粒子和辐射通量的详细模型进行仿真。我们还开发了合成GRB population模型以最佳估计探测率。这些仿真表明，COMCUBE-S每天将探测约2颗GRB，这显著高于过去和当前所有GRB任务的探测率。此外，模拟的极化性能显示，COMCUBE-S将能够唯一区分GRB prompt 辐射的竞争模型，从而为揭示GRB物理学的一些根本方面提供新视角。
