Space-charge-based electrostatic plasma confinement involving relaxed plasma species (open access)

Space-charge-based electrostatic plasma confinement involving relaxed plasma species

In this article, a numerical study is reported on the equilibrium properties of a surface-emitted or edge-confined non-drifting plasma. A self-consistent finite-differences evaluation of the electrostatic potential is carried out for a non-neutral plasma that follows a Boltzmann density distribution.

Low-temperature UV photoluminescence of ion beam synthesized Si nanoclusters embedded in Si (open access)

Low-temperature UV photoluminescence of ion beam synthesized Si nanoclusters embedded in Si

This article explores Ultraviolet (UV) photoluminescence (PL) data taken on a double Au implanted Si matrix and studied over a wide temperature range of 28-220K. The results of this study at lower temperatures indicate the emission to be coming from Si nanoclusters (NCs) embedded in the matrix.

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.
