Abstract The Electron, Proton, and Alpha Monitor (EPAM) is designed to make
measurements of ions and electrons over a broad range of energy and intensity. Through …

This paper reviews three important effects on energetic particles of corotating interaction
regions (CIRs) in the solar wind that are formed at the leading edges of high-speed solar …

Acceleration of interstellar pickup H+ and He+ as well as of solar wind protons and alpha
particles has been observed on Ulysses during the passage of a corotating interaction …

An observational analysis of an atypical energetic particle event near 5 au measured by the
Ulysses spacecraft is presented. A previous study has attributed the unusual enhancement …

SEPServer is a three-year collaborative project funded by the seventh framework
programme (FP7-SPACE) of the European Union. The objective of the project is to provide …

Abstract The Solar Wind and Suprathermal Ion Composition Experiment (SMS) on WIND is
designed to determine uniquely the elemental, isotopic, and ionic-charge composition of the …

The Ulysses spacecraft has been the first to orbit the Sun over its poles and to explore the
heliosphere at these high heliolatitudes. It has now completed two fast latitude scans, one at …

Ulysses observations at 2.5 AU of 38–315 keV electrons and 61–4752 keV ions during
February‐April 1991 suggest in several ways that, during periods of sustained high solar …

Time-series analysis of the fluxes of interplanetary charged particles measured by the
Ulysses and Voyager spacecraft reveals many periodic components. From 1 to 140 µHz, the …

Recent studies of particle acceleration in the heliosphere have revealed a new mechanism
that can locally energize particles up to several MeV nucleon–1. Stream–stream …
