Local Acceleration of Auroral Electrons

  • D. A. Bryant
Part of the Astrophysics and Space Science Library book series (ASSL, volume 57)


Electron precipitation in the vicinity of auroral arcs is discussed. The energy spectra and degree of field alignment are interpreted in terms of an acceleration model in which the energy gain is distributed randomly about the mean value. Some suggestions are made for definitive future measurements.
