The Alpha Magnetic Spectrometer (AMS-02) is a state of the art cosmic ray magnetic detector operating on the International Space Station (ISS) since May 2011, performing a continuous, direct measurement of cosmic ray flux and composition in the rigidity range, \(R=pc/Ze\), \(O(1 \text {GV})-O(1 \text {TV})\). The large statistics collected during 9 years of operation, more than \(1.5\ 10^{11}\) particles, together with the excellent particle identification provided by the instruments, allow for the precise study of the spectra of all cosmic ray species (\(p, He, Li, Be, B, C, N, O \dots \) and \(e^-\)), and begins the exploration of the rare antimatter components (\(\bar{p}, e^+, \bar{D}, \bar{^3He},\bar{^4He} \dots \)), which can be used as probes to search for new physics phenomena. We review the results obtained from the data collected so far, the perspectives of the ongoing analyses and of the forthcoming 10 years of data taking on the ISS.

国际空间站上使用AMS-02进行的高精度宇宙射线物理学

阿尔法磁谱仪(AMS-02)是在国际空间站(ISS)的技术宇宙射线磁检测器的操作的状态,因为2011年5月,在刚性范围进行宇宙射线通量和组合物的一个连续的,直接的测量,\ (R = pc / Ze \)\(O(1 \ text {GV})-O(1 \ text {TV})\)。在运行9年中收集到的大量统计数据超过\(1.5 \ 10 ^ {11} \)个粒子,再加上仪器提供的出色粒子识别功能,可以精确研究所有宇宙射线物种的光谱(\(p,He,Li,Be,B,C,N,O \ dots \)\(e ^-\)),并开始探索稀有的反物质成分(\(\ bar {p},e ^ +,\ bar {D},\ bar {^ 3He},\ bar {^ 4He} \ dots \)),可以用作搜索新物理现象的探针。我们回顾了从迄今为止收集的数据,正在进行的分析以及即将进行的ISS十年数据收集的角度得出的结果。
