Project description
We will investigate the origin of relativistic solar particles. The Alpha Magnetic Spectrometer (AMS) makes possible the precise direct measurement of these particles in space for the first time. The very large collecting power of AMS and operational energy range extending to very high energies with excellent ion identification capabilities makes AMS an exceptional instrument. Many observations indicate that the hypothesis explaining the origin of solar particle events by simply dividing them in two classes corresponding to solar flares and interplanetary shock waves is not a sufficient explanation. The sources of relativistic particles may differ from those of the lower energy ones. To investigate the acceleration mechanisms of relativistic solar particles, AMS observations are combined with those of the SOHO/ERNE instrument of the University of Turku, with observations of the world-wide neutron monitor network and with measurements of electromagnetic radiation at various wavelengths.
