Striation in Gas Discharge,
Abstract
The study of striation indicates that it forms at such pressures, at which there are at least ten collisions of the electron with gas molecules between heads of adjacent striae. At lower pressures, striae diffuse, and the column in all gases becomes uniform. With the exception of the range at such low pressures, the uniform column is comparatively rare and is observed primarily during discharge in sodium, cesium, cadmium, and mercury-vapors. The most common form of column is the layered; moreover, the presence of striae is usually masked by their rapid motion along the discharge. Striae are observed over a broad range of current density (in this work, to j = 300 A/cm3), pressures and diameters of the glow discharge tube. A series of various tests demonstrates that pulsing and stationary striae have a common nature and are fundamentally similar. For instance, pulsing striae may be arrested, and stationary - set in motion.
