Spatio-temporal dynamics of electrons and helium metastables in uniform dielectric barrier discharges formed in He/N₂
AEPT
A uniform atmospheric pressure dielectric barrier discharge is operated in helium with an admixture (0.45%) of nitrogen. The discharge is ignited in the gas gap between a driven and a grounded electrode and propagates along the dielectric surface...
Nonlocal dynamics of secondary electrons in capacitively coupled radio frequency discharges
AEPT
This work utilizes 1d3v Particle-in-Cell/Monte Carlo Collisions (PIC/MCC) simulations of a symmetric discharge in the low-pressure regime with the inclusion of realistic electron-surface interactions for silicon dioxide. A diagnostic framework is...
PIC/MCC simulation for a ns-pulsed glow discharge in nitrogen at sub-atmospheric pressure and analysis of its quasi-steady state physics
EP5
The present study investigates the physics of a nanosecond-pulsed microplasma operated at a pressure of 200 mbar with the help of a particle-in-cell simulation with Monte Carlo treatment of collision (PIC/MCC) and (semi-)analytical models. The...
A new 2D fluid-MC hybrid approach for simulating nonequilibrium atmospheric pressure plasmas: density distribution of atomic oxygen in radio-frequency plasma jets in He/O2 mixtures
AEPT
A spatially two dimensional fluid-MC hybrid (fluid-kinetic) simulation method is developed and applied to the COST reference microplasma jet operated in helium with an oxygen admixture of 0.5\%, excited by a single frequency voltage waveform with...
Validation of in-situ diagnostics for the detection of OH and H2O2 in liquids treated by a humid atmospheric pressure plasma jet
PIP
A humid atmospheric pressure plasma jet was used to treat an aqueous liquid. The transport of hydrogen peroxide and hydroxyl from the plasma to the liquid was analyzed. Two in-situ liquid diagnostics for each species were compared and validated....
Vibrational kinetics in repetitively pulsed atmospheric pressure nitrogen discharges: average-power-dependent switching behaviour
BPT
Characterisation of the vibrational kinetics in nitrogen-based plasmas at atmospheric pressure is crucial for understanding the wider plasma chemistry, which is important for a variety of biomedical, agricultural and chemical processing...

Effects of a radial variation of surface coefficients on plasma uniformity in capacitive RF discharges
AEPT
With the increasing demands towards large area plasma etching and deposition, the radial uniformity of capacitively coupled plasmas (CCPs) becomes one of the key factors that determine process performance in industrial applications. However,...

Zero-dimensional and pseudo-one-dimensional models of atmospheric-pressure plasma jets in binary and ternary mixtures of oxygen and nitrogen with helium background
TET
A zero-dimensional (volume-averaged) and a pseudo-one-dimensional plug-flow (spatially resolved) model are developed to investigate atmospheric-pressure plasma jets operated with He, He/O2, He/N2 and He/N2/O2 mixtures. The models are coupled with...

Computational study of simultaneous positive and negative streamer propagation in a twin surface dielectric barrier discharge via 2D PIC simulations
AEPT
The propagation mechanisms of plasma streamers have been observed and investigated in a surface dielectric barrier discharge (SDBD) using 2D particle in cell simulations. The investigations are carried out under a simulated air mixture, 80% N2...
