Modeling Plasma via Electron Impact Ionization
Variable and potential plasma applications in aerospace engineering are exemplified by ion thrusters, flow control by plasma actuator, enhanced ignition and combustion stability. The operational environments span a range from the rarefied to continuum gasdynamic regimes; however, the ionization process in practical applications is mostly by electron impact. The fundamental ionization mechanisms...
متن کاملClassical simulations including electron correlations for sequential double ionization.
With a classical ensemble model that includes electron correlations during the whole ionization process, we investigate strong-field sequential double ionization of Ar by elliptically polarized pulses at the quantitative level. The experimentally observed intensity-dependent three-band or four-band structures in the ion momentum distributions are well reproduced with this classical model. More ...
متن کاملElectron-impact ionization of Mg
A pulsed crossed beam technique is used to measure ionization cross-sections of metallic atoms. Relative values of cross-sections of single, double and triple ionization of magnesium have been successfully measured with good accuracy over the 0-700 eV range. Absolute values of cross-sections have been obtained by normalization to a theoretical value at high electron energy. Results are compared...
متن کاملAbsolute Electron Impact Ionization Cross
Normalized values of cross sections for the production of ions by electron impact on N20 and NO have been obtained by utilizing the relative flow technique. The accurately known values of cross sections for the production of singly charged ions of rare gases from the parent atoms have been used for the normalization. Cross sections for the generation of fragment ions have been measured for the ...
متن کاملElectron impact ionization of H_2+
The electron impact ionization cross section of H2 is calculated using a distortedwave approximation. The calculated cross section is compared to the experimental results of Peart and Dolder. The simplicity of the system allows an assessment of the accuracy of the distorted-wave approximation without complications from inaccuracies in the target state, initial continuum state, or final continuu...
