WebAs we have shown recently, energetic particle flux enhancements may well originate locally and can be explained by particle acceleration in regions filled with small-scale magnetic islands with a typical width of ∼0.01 au or less, which is often observed near the heliospheric current sheet (HCS). WebThe Energetic Particle Laboratory (EPL) within the Heliospheric Physics Division at GSFC develops novel instruments for the detection of charged and neutral particles. EPL is …
WebWe suggest that the more-general term: "Heliospheric Energetic Particles", which is more descriptive, for which ACRs and other energetic particle species of heliospheric origin are subsets, might be more appropriate.

We discuss energetic neutrons as another possible remote signature, but we rule out γ-ray line and 0.511 MeV positron annihilation emission as observable signatures of heliospheric …
WebIntroduction The heliospheric particles, like pickup ions (PUIs) and energetic neutral atoms (ENAs), and heliospheric phenomena, like the resonant backscatter glow in the solar hydrogen (121.6nm) and helium (58.4nm) lines, result from interaction of the interstellar medium with the solar output inside the heliosphere.
