Analysis of Auroral Electron Data.
Abstract
Auroral electron data obtained by rocket measurements as part of the ICECAP program are analyzed. The measurements were made by a spherical plate electrostatic analyzer along with scintillators. The differential energy spectra of electrons measured in each of the rocket flights were quite different. In one flight the spectra (measured from 4 to 30 keV) peaked at 16 keV (full width half maximum about 8 keV) as the rocket overflew the auroral arc (maximum energy deposition about 30 ergs/sq. cm. -sec-sr). As the rocket overflew the arc in the second flight, peak appeared in the spectra near 12 keV and shifted to beyond 30 keV in the region of maximum precipitation (>100 ergs/sq. cm -sec-sr). In this region the measured spectra were relatively flat with the differential intensity a factor of 3 higher at 30 keV than at 4 keV. The ion-electron production rate is calculated for each flight. The 3914A emission rate and the electron density are computed from the production rate and compared with the rocket measurements. (Author)
