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

By employing multi-frame laser interferometry, shadow, and schlieren imaging, we trace the
formation of a nanosecond spark discharge in millimeter-sized air gaps formed by a point …

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 …

Self-organization refers to the spontaneous generation of spatially or temporally organized
patterns in an otherwise disordered system. Self-organization is ubiquitous in plasma …

Radially symmetric patterns are observed in pin-to-plane DC plasma systems where a liquid
solution is used as a planar resistive anode. The size and structure of these patterns …

Using laser Thomson scattering (LTS) and 2D optical imaging, a fireball-like discharge is
detected during the positive pulse period of bipolar voltage waveforms, for a circular planar …

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 stable fireball is produced in front of a positively biased metal disc inside a filamentary dc
discharge argon plasma. The measurement of the axial potential profile from the bulk …

Experimental investigations of a hollow cathode discharge through the controlled variation
of anode potential inside a hollow cylindrical cavity, in the absence and presence of the …

Recent one-dimensional simulations of planar sheaths with strong electron emission have
shown that trapping of charge-exchange ions causes transitions from space-charge limited …
