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

I–V traces of strongly emitting emissive probes are investigated in a multidiople filament
discharge. It is found that at sufficiently high neutral pressure and emitting current, the …

Plasma boundary layers are susceptible to electrostatic instabilities driven by ion flows in
presheaths and, when present, these instabilities can influence transport. In plasmas with a …

Abstract In E× B sources with different degrees of magnetization between electrons and
ions, collisionless Simon–Hoh instability is prone to be induced, which may result in long …

The Bohm sheath criterion was studied with laser-induced fluorescence (LIF) in three ion
species plasmas using two tunable diode lasers. It was found in the first LIF studies of three …

This study investigated the transition of the plasma shape from a ring-shaped bullet to a pin-
like streamer adjacent to the electrolyte surface in a kHz-driven helium atmospheric …

Recent studies have demonstrated that the two-ion-stream-instability occurs near the
plasma boundary and makes the ions reach the'modified Bohm velocity'at the sheath edge …

The blisters formation and destruction induced by the deuterium ions on a polycrystalline
tungsten were investigated with varying irradiation deuterium ion fluence from 3.04× 10 23 …

The Instability Enhanced Friction theory [Baalrud et al., Phys. Rev. Lett. 103, 205002 (2009)]
is extended to account for the influence of neutral pressure in predicting the flow speed of …
