Most photons detected by PIXIE (the X-ray imager aboard GGS/Polar and the first instrument to provide global X-ray images of Earth) have resulted from precipitation of auroral electrons. Here we trace magnetic field lines (from the high-latitude iono

The Polar Ionospheric X-ray Imaging Experiment (PIXIE) on the GGS/Polar satellite provides global energy-resolved (2-60 keV) X-ray images of Earth from an apogee altitude ∼ 5 x 10 4 km. In the present study we analyze PIXIE data from the magnetic s

An interpretation is given for the high fluxes of 0+ ions with energies to 12 kev observed during the magnetic storm of 17 December 1971. It is suggested that the ions were accelerated initially by the absorption, near the altitude of the 0+ resonanc

A light pulse generator is described which utilizes a flash lamp and a 5000 revolutions per second rotating mirror. A variety of light pulse shapes can be produced having widths from 1.16×10−9 seconds to 10−6 second.

The gradient of the geomagnetic field may appreciably affect the energy that can be exchanged in resonant interactions between charged particles and circularly polarized waves. The equations of motion of a charged particle resonating with a circularl

Evidence for the acceleration of trapped particles by magnetic fluctuations produced by ionospheric currents is derived from the observations of sharp-energy groups of high-energy electrons that, at least on one occasion, appeared suddenly at low L s

A new field-line resonance is proposed to explain some coherent modulations of trapped proton and electron fluxes with correlated magnetic-field variations that have been observed in the outer magnetosphere. The resonance is excited by the ▽B drift

The geomagnetic field, like other large-scale phenomena found in nature, is never absolutely quiescent or undistrubed. Field measurements versus time show a variety of disturbances having time durations lasting from a fraction of a second to as long

This section presents a brief review of the trapped radiation environment in the Earth's vicinity. Models of the proton and electron environments in epochs of solar maximum and solar minimum are described. Results of some updated data analysis are us
