Spectroscopic Characterisation of an Atmospheric Pressure Glow Discharge*
Recently there has been considerable interest in atmospheric discharges operating in a glow discharge mode i.e. with a spatial and sheath structure similar to that of low pressure glow discharges [1,2,3]. Here spectroscopy has been used to characterise an atmospheric pressure glow discharge (APGD), operating with either dry air, argon or helium gas flowing through the inter-electrode space and ...
متن کاملSpatial profiles of N2 concentration in an atmospheric pressure nitrogen glow discharge
Spatial profiles of N2 concentration are measured in an atmospheric pressure nitrogen glow discharge by cavity ring-down spectroscopy. At discharge currents of ∼100 mA, we measure centreline ion concentrations on the order of 1012 cm−3, and radial profiles with radial-half-maximum of ∼1 mm. The measurements have sub-ppm concentration sensitivity, and sub-millimetre spatial resolution. Using a c...
متن کاملAttenuation of single-tone ultrasound by an atmospheric glow discharge plasma barrier
Propagation of 143 kHz ultrasound through an atmospheric pressure glow discharge in air was studied experimentally. The plasma was a continuous dc discharge formed by a multipin electrode system. Distributions of the gas temperature were also obtained in and around the plasma using laser-induced Rayleigh scattering technique. Results show significant attenuation of the ultrasound by the glow di...
متن کاملDynamics of an excitable glow-discharge plasma under external forcing.
Glow discharge plasma in the excitable regime shows rich dynamical behavior under external forcing. By perturbing the plasma with a subthreshold sawtooth periodic signal, we obtained small subthreshold oscillations that showed resonance with the perturbation frequency. The resonance phenomenon can be useful to estimate characteristic of an excitable system. However, for suprathreshold perturbat...
متن کاملSimulation and Model Reduction Methodsfor an RF Plasma Glow Discharge
In this paper, we report on numerical solutions and model reduction results for a plasma glow discharge model with a radio frequency ionization source. A pseudospectral implementation of a global spectral method was found to give accurate simulation results that correctly reflected the expected physical behavior of an argon plasma under the simulated operating conditions. Numerical residual ana...
