High Energy Radiation Near the Earth

Abstract

It is well to have a term which specifically denotes the solar high-energy particles, in contradistinction to the galactic cosmic rays and the low-energy particles which come from the sun and which are responsible for the aurora, magnetic storms and so forth. A term for solar high-energy particles, which is currently being used by such people as Neher, Gold, Kellogg and Winckler, is the SHEP. As SHEPs consist mainly of protons, this terminology might also stand for “solar high-energy proton.” To be specific, however, we usually speak of SHEP-protons, SHEP-alphas, etc.
