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. |
