Journal ArticleDOI
Cold-cathode discharges and breakdown in argon: surface and gas phase production of secondary electrons
A. V. Phelps,Z. Lj. Petrović +1 more
TL;DR: In this article, the authors present the data and models describing the secondary electrons that initiate the secondary and subsequent feedback avalanches required for the growth of current during breakdown and for the maintenance of low-current, cold-cathode discharges in argon.
Journal ArticleDOI
Anisotropic scattering of electrons by N2 and its effect on electron transport.
A. V. Phelps,Leanne Pitchford +1 more
TL;DR: The changes in the commonly measured transport and reaction coefficients resulting from the introduction of anisotropic elastic and inelastic scattering, while keeping the elastic momentum-transfer cross section constant, are less than 1%.
Journal ArticleDOI
Cross Sections and Swarm Coefficients for Nitrogen Ions and Neutrals in N2 and Argon Ions and Neutrals in Ar for Energies from 0.1 eV to 10 keV
TL;DR: In this paper, cross sections for elastic, excitation, and ionization collisions of N+, N+2, N, and N2 with N2 and for Ar+ and Ar with Ar for laboratory energies from 0.1 eV to 10 keV are presented.
Journal ArticleDOI
The application of scattering cross sections to ion flux models in discharge sheaths
TL;DR: In this paper, consistent sets of Ar++Ar and Ar+++Ar differential and integral cross sections for modeling ion scattering that take into account differential scattering data and the fact that symmetric charge transfer collisions are one aspect of elastic scattering collisions are presented.
Journal ArticleDOI
Predicted electron transport coefficients and operating characteristics of CO2–N2–He laser mixtures
TL;DR: In this article, the transport coefficients of electrons in gas mixtures for ratios CO2:N2:He of 1:1:8, 1:2:3, 1 :7:30, and 1:0.25:3 were derived.
