Spatially Periodic Electromagnetic Force Field For Plasma Confinement and Control (open access)

Spatially Periodic Electromagnetic Force Field For Plasma Confinement and Control

In this article, a theoretical understanding is developed of the single-particle reflection properties of a force field, considering the incident charged particles to have a non-drifting, isotropic velocity distribution. Classical trajectory Monte Carlo simulations and analytical modeling are employed. The initiation of an experimental effort to study force fields is described.
