Alpha 磁谱仪 (AMS) 是一种粒子物理探测器，设计用于测量高达 TV 区域的带电宇宙射线光谱，具有高达数百 GeV 的高能光子探测能力。 AMS 是一种超导光谱仪，具有广泛的接受度、较长的使用寿命（磁铁至少三年）和最先进的粒子识别技术。 AMS 将以高统计量研究宇宙射线的成分，并为反物质核的存在和暗物质的性质提供最灵敏的搜索。该探测器由大型超导磁体内部的八层硅跟踪器构成，提供约 0.8 Tm2 的弯曲功率和约 0.4 m2 sr 的接受能力。跃迁辐射探测器和三维电磁量热仪可进行电子、正电子和光子识别，而飞行时间闪烁系统和环形图像切伦科夫探测器则执行独立的速度测量。这种复杂的设备将识别和测量直至铁的原子核。我们将描述探测器的整体结构和性能，该探测器将于 2006 年完成。该探测器将于 2008 年安装在 ISS（国际空间站）上
The Alpha Magnetic Spectrometer (AMS) is a particle physics detector designed to measure charged cosmic ray spectra up to the TV region, with high-energy photon detection capability up to few hundred GeV. AMS is a superconducting spectrometer with large acceptance, long duration (at least three years for the magnet) and state of the art particle identification techniques. AMS will investigate the composition of cosmic rays with high statistics and provide the most sensitive search for the existence of antimatter nuclei and for the nature of dark matter. The detector is being constructed with an eight-layer Silicon Tracker inside a large superconducting magnet, providing a ~0.8 Tm2 bending power and an acceptance of ~0.4 m2 sr. A Transition Radiation Detector and a three-dimensional Electromagnetic Calorimeter allow for electron, positron and photon identification, while a Time of Flight scintillating system and a Ring Image Cerenkov detector perform independent velocity measurements. This complex apparatus will identify and measure nuclei up to Iron. We will describe the overall detector construction and performance, which is due to be completed by 2006. The detector will be installed on ISS (International Space Station) in 2008
