Alfveacuten continuum deformation by kinetic geodesic effect in rotating tokamak plasmas
(AMER INST PHYSICS, 2010)
Using a quasitoroidal set of coordinates with coaxial circular magnetic surfaces, Vlasov equation is solved for collisionless plasmas in drift approach and a perpendicular dielectric tensor is found for large aspect ratio ...
Ion beam measurements in a small plasma focus operating in hydrogen/gas mixtures
(IEEE, 1998)
Dense transient plasmas of high energy density, can be easily produced in a plasma focus device, on a cost effective basis. High energy ion beam emission is one, among several others, of the very interesting transient ...
Recurrence quantification analysis of turbulent fluctuations in the plasma edge of Tokamak Chauffage Alfveacuten Breacutesilien tokamak
(AMER INST PHYSICS, 2010)
Recurrences are close returns of a given state in a time series, and can be used to identify different dynamical regimes and other related phenomena, being particularly suited for analyzing experimental data. In this work, ...
Reduction of chaotic particle transport driven by drift waves in sheared flows
(AMER INST PHYSICS, 2008)
Investigations of chaotic particle transport by drift waves propagating in the edge plasma of tokamaks with poloidal zonal flow are described. For large aspect ratio tokamaks, the influence of radial electric field profiles ...
Time-Varying Inductance of the Plasma Sheet in the PF1000 Plasma-Focus Device
(Institute Of Electrical And Electronics Engineers, 2016-05)
The time-varying inductance Lp(t) of the system formed by the coaxial electrodes and the current sheet (CS) in plasma focus (PF) discharges was calculated for the first time by Mather and Bottoms [1] on a 13-kJ PF device ...
Experimental investigations of hotspots in a low energy plasma focus operating in hydrogen-argon mixtures
(IEEE, 1998)
We present experimental results on the investigation of hotspot formation in PFP-I, a small 3.8 kJ plasma focus device operating in hydrogen-argon mixtures, at pressures from below 0.2 torr upward. A combination of ...
Four-electrodes DBD plasma jet device with additional floating electrode
(Springer, 2020-01-24)
A Dielectric Barrier Discharge (DBD) plasma jet in a four electrodes configuration was investigated in order to improve the discharge parameters, such as discharge power and rotational and vibrational temperatures of ...
Design optimization of an air atmospheric pressure plasma-jet device intended for medical use
(Wiley VCH Verlag, 2018-03)
The current and potential applications of atmospheric pressure plasmas in medicine generate an increasing need to develop safe and reliable plasma devices for patient treatment. This paper shows how the estimation of safety ...
