摘要

空间下一代磁谱仪AMS-100设计几何接受度为100m2sr100\,\mathrm{m}^2\,\mathrm{sr},并计划在日地拉格朗日点2运行至少十年。与现有实验相比,它将把观测宇宙线特别是宇宙反物质中新现象的灵敏度至少提高1000倍。磁体设计基于高温超导带材,可建造一个内部均匀磁场为1特斯拉的薄螺线管。内部体积配备硅径迹探测器,最大可探测刚度达100 TV,以及深70个辐射长度(相当于4个核相互作用长度)的量能器系统,将宇宙线原子核的能量探测范围扩展至PeV尺度,即超越宇宙线膝区。AMS-100连续覆盖大部分天空,将在量能器系统中探测高能伽马射线,并通过薄螺线管中的对产生、由硅径迹探测器以优异角分辨率重建。
