Emission of Electron Bernstein Waves

Electron collection by a negatively charged sphere in a collisionless magnetoplasma

Easy-to-evaluate approximate formulas are presented for the repelled-species current collected by a spherical body in a collisionless, magnetized plasma, valid over the full range of ratio of Larmor radius to sphere radius. The form is an appropriate average of the lower and upper bounds obtained by prior analytic arguments. This formulation enables rapid evaluation of the floating potential in...

Charging of Dust Particles in Collisionless Plasma Sheath with Non-maxwellian Electron Energy Distribution Function

The key parameter driving behavior of dust particles in plasma is their electric charge [1]. Present-day theories as well as experiments are not fully successful in determining its value [2]. Moreover, the theoretical uncertainties are increased in the plasma sheath – a think plasma layer at a wall or electrode. The standard models of dust charging in the plasma sheath usually suppose Maxwellia...

Psfc/ja-02-17 Electron Bernstein Waves in Spherical Tori

This paper summarizes the theoretical and numerical results we have obtained for the excitation and propagation of electron Bernstein waves in spherical tokamak plasmas. INTRODUCTION In the electron cyclotron range of frequencies the high-β NSTX and MAST plasmas are overdense to the traditional extraordinary X mode and/or the ordinary O mode. For low harmonics of the electron cyclotron frequenc...
