Abstract The Loss Cone Imager (LCI) instrument package on the US Air Force׳ s
Demonstration and Science eXperiment (DSX) mission is expected to provide in-situ …

Abstract The Energetic Particle Detector (EPD) Investigation is one of five particles and fields
investigations on the Magnetospheric Multiscale (MMS) mission. This mission consists of …

We analyze the response of relativistic electrons to the 276 moderate and intense
geomagnetic storms spanning the 11 years from 1989 through 2000. We find that …

We present observations of the radiation belts from the Helium Oxygen Proton Electron and
Magnetic Electron Ion Spectrometer particle detectors on the Van Allen Probes satellites that …

Many theoretical models have been developed to explain the rapid acceleration to
relativistic energies of electrons that form the Earth's radiation belts. However, after decades …

The origin and dynamics of the Van Allen radiation belts is one of the longest-standing
questions of the space age, and one that is increasingly important for space applications as …

The Solar, Anomalous and Magnetospheric Particle Explorer (SAMPEX) satellite frequently
observes relativistic (> 1 MeV) electron precipitation in the radiation belts at L shells of 4–6 …

Bursty precipitation of relativistic electrons has been implicated as a major loss process
during magnetic storms. One type of precipitation, microbursts, appears to contain enough …

Experimental techniques and instrumentation for space plasma imaging in fluxes of
energetic neutral atoms (ENAs) are reviewed. ENAs are born in charge exchange collisions …

We investigate how relativistic electrons are lost from the Earth's magnetosphere in order to
better understand the dynamic variability of the radiation belts. We identify 52 events where …
