Download or read book Pulsed Microwave Breakdown in Gases with a Low Degree of Preionization written by E. F. Dawson and published by . This book was released on 1972 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper presents the results of experimetns on microwave breakdown at an open end waveguide antenna in Air, Argon, Nitrogen, Carbon Dioxide and Methane at pressures of 0.3 and 30 Torr. The antenna was operated at 9.375 GHz under pulsed conditions at varying pulse rates. Very low degrees of preionization were obtained by adjusting to very slow pulse rates. The power needed to maintain the discharge was measured and from that the electric field strength was calculated. This presented as a function of pressure for each gas at pulse rates ranging from 10 to 500 pulses per second. At low pulse rates, significantly higher power levels are needed to maintain the discharge. An interesting feature is the double minima observed at low pulse rates in the data for breakdown field strength as a function of pressure for Carbon Dioxide and Methane. The data was also used to calculate ionization frequency as a function of effective electric field for all give gases. Where possible, this data is compared with data reported by other investigators.

Download or read book Microwave Breakdown Calculations that Include the Effects of Preionization in Neon and Neon argon Mixtures written by Mark R. Foster and published by . This book was released on 1973 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program has been written to calculate the electric field required to initiate microwave breakdown in a partially ionized gas. The breakdown field is found by calculating ionization rates and diffusion loss rates and then solving for the value of the electric field at which these rates balance. In the preionization case, a modified diffusion coefficient is required to account for charge-separation effects. The program reported here uses the method of MacDonald for calculating ionization and diffusion loss rates and extends that method to the preionization case by using a multiplicative factor to model the transition to ambipolar diffusion. Results are graphed for neon and neon-argon mixtures using various values of the characteristic diffusion length and signal frequency over a range of gas pressures.
Download or read book Microwave Theory and the Breakdown of Gases by Ruby Laser Radiation written by Richard G. Tomlinson and published by . This book was released on 1963 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave breakdown theory is extrapolated to the 6943 Angstroms, ruby laser wavelength. The need for breakdown criterion other than that for the critical plasma frequency, sometimes used in microwave breakdown, is shown. A suitable criterion is developed from the solution of the electron density continuity equation, including recombination loss. A solution for the breakdown electric field strength, or power density, for the pulsed ruby laser in air as a function of pressure is obtained. The effect of varying pulse duration, initial electron density, and characteristic diffusion length is shown. A minimum power density of 10 to the 12th power watts/sq. cm is predicted for breakdown of air by ruby laser radiation. The extent of accuracy of the results of extrapolating microwave breakdown theory to optical laser breakdown is discussed; and there is speculation on the possibility of additional effects peculiar to laser breakdown.
