A weak DC magnetic field is applied to an immersed helical resonator antenna in an RF plasma to study the effects of magnetic insulation on potential differences between plasma and antenna within the vacuum chamber. Past research suggests a link between minimizing antenna potential and mitigating self-sputtering effects within the chamber to minimize debris creation. Alteration of particle flux...

We review the basic approximations underlying magnetohydrodynamic (MHD) theory, with special emphasis on the closure approximations, i.e. the approximations used in any fluid approach to close the hierarchy of moment equations. We then present the main closure models that have been constructed for collisionless plasmas in the large-scale regime, and we describe our own mixed MHD-kinetic model, ...

This open access textbook teaches PhD students the physics of Earth's radiation belts from plasma theory to latest observations by Van Allen probe.

Fast time averaged equations are derived for the motion of particles and the generation of electromagnetic wake fields under the action of the ponderomotive potential of an ultraintense laser pulse propagating through a tenuous plasma. Based on these averaged equations, a new particle code is designed which calculates the particle trajectories on the plasma period time scale. The regime of tota...
