FACTORS AFFECTING THE GROWTH OF BOUNDARY LAYERS IN PLASMA ACCELERATORS.
Abstract
The aim of the research was to investigate some aspects of the interaction between a seeded plasma and the electrode or non-electrode walls of plasma accelerators or generators. The problem was complicated over that of conventional plasma flow because a seeded gas was involved, and consequently the physics of surface - gas interaction required some investigation. The program included experimental investigations of the properties of seeded plasmas, stability of the plasma flow, ionization rates and ionization mechanism, as well as boundary-layer type analysis. The work was divided into three different parts: (1) boundary layer analysis and gas phase and surface phenomena affecting the electrical properties of potassium-seeded argon, (2) ionization rates and ionization mechanisms in the noble gases, (3) stability of the plasma flow under the action of electrical and magnetic fields.
