TLDR
In this paper, the results of a rocket borne electric field experiment flown near local midnight from Andenes, Norway have been transformed to an Earth-fixed coordinate system and compared with plasma temperature and density measurements, energetic particle fluxes, and perpendicular electric field variations, to strengthen the earlier conclusion that ∼10 mV/m electric fields existed parallel to the magnetic field line during the flight.About:

Auroral arc classification scheme based on the observed arc-associated electric field pattern
TL;DR: In this article, a classification of different arc types based on the relative influence on the electric field pattern from the two current continuity mechanisms, polarization electric fields and Birkeland currents, is presented.

Origin and effects of electric fields during isolated magnetospheric substorms
TL;DR: In this article, balloon-measured electric field data for five-hour periods during each of 19 substorms near local midnight have been analyzed and averaged and applied to an improved model of the magnetospheric substorm in which the origin of the electric fields, the flow of cold plasma and magnetic-field lines, and many observed particle phenomena are more naturally explained.

Kinetic theory of the Alfvén wave acceleration of auroral electrons
Robert L. Lysak,Yan Song +1 more
TL;DR: In this paper, a nonlocal theory based on a simplified model of the ionospheric Alfven resonator (IAR) is presented, which indicates that wave acceleration of electrons should occur at and above the altitude where the quasi-static potential drops form.

Numerical simulation of global formation of auroral arcs
Akira Miura,Tetsuya Sato +1 more
TL;DR: In this paper, a global simulation of auroral arcs is performed, based on the feedback theory of Sato, for a three-dimensionalally coupled ionosphere-magnetosphere system which includes two pairs of large-scale Birkeland currents, large scale polar cap electric fields, and a day-night asymmetry of the electron density distribution.

Analyses of techniques for measuring DC and AC electric fields in the magnetosphere
TL;DR: In this article, the amplitudes and directions of DC electric fields and the directions, power spectra, and dispersion relations of AC electric fields in the magnetosphere are discussed with emphasis on their applicability in various regimes of the magnetospheric plasma.

A mechanism for energizing electrons in the magnetosphere
TL;DR: In this article, an electrodynamic heating mechanism is proposed to account for the precipitation of kilovolt energy electrons during an auroral disturbance, given the existence of an electric field transverse to the geomagnetic field caused by space charges in the magnetosphere, currents will flow along the magnetic field connecting the space charges to the conducting ionosphere.

Effects of Field-Aligned Currents on the Structure of the Ionosphere
TL;DR: The influence of electric currents along the magnetic field lines on the high-latitude F-layer ionosphere is investigated theoretically in this paper, where it is shown that a current of either sign leads to a reduction of the total electron content and the maximum density, if the charge carriers have to be produced in the ionosphere.

Investigation of the operation of a d.c. electric field detector
TL;DR: In this article, double-lungmuir probe detector systems have been successfully used on three rockets in the past two years to measure quasi-static and a.c. electric fields in the auroral zone ionosphere.
