Investigation of “Thick Grid” Plasma Switches for Thermionic System Output Voltage

Plasma switches ( Cs and Cs-Ba tacitrons PS ) with thick grid have grid with thickness more than mesh aperture size. These grids have some advantages as compared with small-scale /1.2/ ones, for instance, much more electrical strength.

This paper contains the “thick-grid” investigation results; the grid controle efficiency, the plasma parameteres, probe researches of these parameteres at conductive state and their variety during the process of quenching. The results showed the “thick-grid” PS plasma differed from the “thin - grid” PS signyficantly at the stationary state as well as by quenching dynamic features.
