Abstract:

Results obtained from a theoretical and experimental study of the transport of charged particles through gases and plasmas are summarized. Experimental current-voltage characteristics of a cylindrical hot cathode gas diode filled with various gases have been compared with theoretical curves obtained when using experimental electron drift velocity data in the calculations. Good agreement was obtained. An experimental tube for studying the influence of space-charge neutralization by positive ions on current-voltage characteristics has been constructed. Application of macroscopic transport equations to the theory of electrophoresis results in a new formulation of this phenomenon. The same method was applied to the theory of cataphoresis. A theoretical study of radial gas density variations in direct current discharge tubes was started. Author
