The latest low energy results from the Alpha Magnetic Spectrometer (AMS) on the International Space Station
The Alpha Magnetic Spectrometer (AMS), on the International Space Station since May 2011, has acquired the largest number of particles ever measured in space by a single experiment, performing the most precise measurement of galactic cosmic rays (GCR) to-date. A series of 4 very complicated EVAs extended the lifetime of the instrument and allow the taking of data for the entire lifetime of the space station. The detailed time variation of multiple particle species of GCR fluxes, measured during solar cycle 24, will be presented together with results on short-term solar activity, including Forbush decreases (FDs) and solar energetic particles (SEPs). These results provide an invaluable resource for understanding the space radiation environment for future manned missions to the Moon and Mars, and for improving space weather forecasting capabilities.
