Properties of hot-spots in Plasma Focus discharges operating in Hydrogen-gas mixtures
(IEEE, 2002)
We have investigated the properties of hotspots formed in low energy Plasma Focus discharges operating in Hydrogen-Argon mixtures, at 140 kA current level. The results show that best conditions for reproducible and localized ...
Sterilization by pure oxygen plasma and by oxygen-hydrogen peroxide plasma: An efficacy study
(ELSEVIER SCIENCE BV, 2008)
Plasma is an innovative sterilization method characterized by a low toxicity to operators and patients, and also by its operation at temperatures close to room temperatures. The use of different parameters for this method ...
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 ...
On the determination of plasma electron density from Stark broadened hydrogen Balmer series lines in Laser-Induced Breakdown Spectroscopy experiments
(Elsevier, 2013-06)
In this work, different theories for the determination of the electron density in Laser-Induced Breakdown Spectroscopy (LIBS) utilizing the emission lines belonging to the Hydrogen Balmer series have been investigated. ...
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 ...
Effect of the admixture of N2to low pressure, low temperature H2-CH4-CO2microwave plasmas used for large area deposition of nanocrystalline diamond films
(2020-11-04)
In a distributed antenna array reactor, microwave H2-CH4-CO2 plasmas with admixture of N2 used for the low-temperature deposition of nanocrystalline diamond (NCD) films are studied by in situ infrared laser absorption ...
Effects of gas composition during plasma modification of polyester fabrics
(ELSEVIER, 2006)
In order to increase the hydrophilicities and to improve dyeability, poly(ethylene terephathalate) (polyester) fabrics were treated in low pressure and temperature plasma. Different plasma atmosphere were used in this work, ...
