Description
The Alpha Magnetic Spectrometer, AMS, is a general purpose high energy particle physics detector. It was installed on the International Space Station, ISS, on 19 May 2011 to conduct a unique long duration mission of fundamental physics research in space.
In this contribution, precision measurements by AMS of the primary cosmic ray positron flux, electron flux and antiproton flux are presented. These measurements increase the precision of the previous observations and significantly extend their energy range. Based on these measurement, new observations of the properties of the flux ratios of charged elementary particles in cosmic rays are presented. Together, they provide important information on the origins of cosmic-ray charged elementary particles.
