Parallel Acceleration of Suprathermal Electrons Caused by Whistler‐Mode Hiss Waves

A pr 2 00 4 Stochastic Acceleration of Electrons and Protons . I . Acceleration by Parallel Propagating Waves

Stochastic acceleration of electrons and protons by waves propagating parallel to the large scale magnetic fields of magnetized plasmas is studied with emphasis on the feasibility of accelerating particles from a thermal background to relativistic energies and with the aim of determining the relative acceleration of the two species in one source. In general, the stochastic acceleration by these...

Dispersion relation for electron waves propagating in an isotropic plasma containing Maxwellian and suprathermal electrons

The paper discusses the dispersion relation for longitudinal electron waves propagating in a collisionless, homogeneous isotropic plasma, which contains both Maxwellian and suprathermal electrons. I t is found that the dispersion curve, known to have two separate branches for zero suprathermal energy spread, depends sensitively on this quantity. As the energy half-width of the suprathermal popu...

Rapid Acceleration of Electrons in the Magnetosphere by Fast-mode Mhd Waves

During major magnetic storms enhanced fluxes of relativistic electrons in the inner magnetosphere have been observed to correlate with ULF waves. The enhancements can take place over a period of several hours. In order to account for such a rapid generation of relativistic electrons, we examine the mechanism of transit-time acceleration of electrons by low-frequency fast-mode MHD waves, here th...

Nonlinear Production of Suprathermal Tails in Auroral Electrons

Differential energy spectra of electrons observed in an auroral breakup show evidence that an incident electron beam of energy E = 6-13 keV, width of 2-5 keV, and variable intensity was stabilized over a period of at least several minutes by the oscillating two-stream instability in the manner previously described by Papadopoulos and Coffey. The critical observed feature predicted by these auth...
