摘要(中)

反物質磁譜儀(Alpha Magnetic Spectrometer, AMS-02)是裝設在國際太空站(ISS)上的粒子探測器，自2011年運行至今;AMS-02用來精確量測宇宙射線流與其組成，以及搜索太空中反物質與暗物質的存在，其目的在於探討基本物理與宇宙起源之問題。
初級宇宙射線的分析為實驗中重要的一環。初級宇宙射線為總量最多的宇宙射線，如質子、氦、氧、碳等元素，其光譜揭示了宇宙射線的加速和傳播過程。
這份分析結果利用反物質磁譜儀精確測量宇宙中的碳元素通量，在絕對剛度區間1.9GV至2.6TV，並從2012年9月28日至2017年8月8日期間收集5年83萬筆數據。

摘要(英)

The Alpha Magnetic Spectrometer (AMS-02) is a particle detector which is operated on the International Space Station (ISS). It’s for precisely measuring the cosmic ray composition and flux, and searching for anti- matter and dark matter. AMS-02 aims at helping answer fundamental questions and the origin of universe.
The primary cosmic ray, which are protons and heavier nuclei, like He- lium, Oxygen, and Carbon, is among the most abundant nuclei in cosmic rays. Their spectra carry information about the cosmic ray propagation.
This analysis discussed a measurement of the carbon flux with the absolute rigidity range from 1.9 GV to 2.6 TV, which is based on the data collected by AMS on the ISS.
