Numerical study of secondary electron emission in a coaxial radio-frequency driven plasma jet at atmospheric pressure

Torben Hemke, Jan Trieschmann, Alexander Wollny +2

In this work we investigate a numerical model of a coaxial RF-driven plasma jet operated at atmospheric pressure. Due to the cylindrical symmetry an adequate 2-D representation of…

Spatially resolved simulation of a radio frequency driven micro atmospheric pressure plasma jet and its effluent

Torben Hemke, Alexander Wollny, Markus Gebhardt +2

Radio frequency driven plasma jets are frequently employed as efficient plasma sources for surface modification and other processes at atmospheric pressure. The radio-frequency dri…

Self-pulsing of a micro thin cathode discharge

Alexander Wollny, Markus Gebhardt, Torben Hemke +2

Microplasmas operated at atmospheric pressure show a number of peculiar dynamic phenomena. One of these phenomena is self-pulsing, which is characterized by intrinsic pulsing behav…

Fine-sorting One-dimensional Particle-In-Cell Algorithm with Monte-Carlo Collisions on a Graphics Processing Unit

Philipp Mertmann, Denis Eremin, Thomas Mussenbrock +2

Particle-in-cell (PIC) simulations with Monte-Carlo collisions are used in plasma science to explore a variety of kinetic effects. One major problem is the long run-time of such si…

Ionization wave propagation on a micro cavity plasma array

Alexander Wollny, Torben Hemke, Markus Gebhardt +7

Microcavity plasma arrays of inverse pyramidal cavities have been fabricated in p-Si wafers. Each cavity acts as a microscopic dielectric barrier discharge. Operated at atmospheric…
