Energy and angular distribution of auroral particles resulting from time-varying acceleration
Abstract
A model is presented with a static electric field parallel to the magnetic field lines, and time-varying acceleration responsible for the auroral precipitation. The energy spectra and angular distribution of the auroral particles which predicted using this model are discussed and compared to observations of field aligned electrons made from the sounding rocket launched from Kiruna, Sweden, on 22 November 1971 at 135 km altitude during the expansion phase of an auroral substorm.
