Abstract The Advanced Composition Explorer was launched August 25, 1997 carrying six
high-resolution spectrometers that measure the elemental, isotopic, and ionic charge-state …

We report spacecraft measurements of the energy spectra of solar protons and other solar
energetic particle properties during the 16 Ground Level Events (GLEs) of Solar Cycle 23 …

We have evaluated the energetics of 38 solar eruptive events observed by a variety of
spacecraft instruments between 2002 February and 2006 December, as accurately as the …

Above a few tens of MeV per nucleon, large, gradual solar energetic particle (SEP) events
are highly variable in their spectral characteristics and elemental composition. The origin of …

We report on abundance measurements of 10 Be, 26 Al, 36 Cl, and 54 Mn in the Galactic
cosmic rays (GCRs) using the Cosmic-Ray Isotope Spectrometer (CRIS) instrument aboard …

Using coordinated observations from instruments on the Advanced Composition Explorer
(ACE), the Solar and Heliospheric Observatory (SOHO), and the Ramaty High Energy Solar …

The extraordinary period from late October through early November 2003 was marked by
more than 40 coronal mass ejections (CME), eight X‐class flares, and five large solar …

A new catalogue of 314 solar energetic particle (SEP) events extending over a large time
span from 1984 to 2013 has been compiled. The properties as well as the associations of …

Abstract The Cosmic-Ray Isotope Spectrometer is designed to cover the highest decade of
the Advanced Composition Explorer's energy interval, from∼ 50 to∼ 500 MeV nucl-1, with …

This open access book serves as a concise primer introducing the non-specialist reader to
the physics of solar energetic particles (SEP). It systematically reviews the evidence for the …
