Biased electrodes are common components of plasma sources and diagnostics. The plasma–
electrode interaction is mediated by an intervening sheath structure that influences …

This paper describes the verification and validation (V&V) framework developed for the
stochastic Particle-in-Cell, Direct Simulation Monte Carlo code Aleph. An ideal framework for …

In this work, we examine sheath formation in the presence of bias potentials in the current
saturation regime for pulsed power fusion experiments. It is important to understand how the …

What effect does a dielectric material surrounding a small positively biased electrode have
on the ion flow and sheath structure near the electrode? Measurements of the ion velocity …

In this work, an improved understanding of electron sheath theory is provided using both
fluid and kinetic approaches while elaborating on their implications for plasma–surface …

Electrostatic flow-driven instabilities have been predicted in the presheath region of low-
temperature plasmas for both ion and electron rich sheaths. The ion-acoustic fluctuations …

Electron sheaths form near the surface of objects biased more positive than the plasma
potential, such as a Langmuir probe collecting electron saturation current. Generally, the …

Self-organized patterns of spots on a flat metallic anode in a cylindrical glow discharge tube
are simulated. A standard model of glow discharges is used, comprising conservation and …

A highly parallelizable fluid plasma simulation tool based upon the first-order drift-diffusion
equations is discussed. Atmospheric pressure plasmas have densities and gradients that …

When electrodes are biased above the plasma potential, electrons accelerated through the
associated electron sheath can dramatically increase the ionization rate of neutrals near the …
