Abstract

The structure of plasma sheath formed in front of an absorbing material wall for different temperatures of the in-streaming particles has been studied. For given electron and ion distributions of the sheath entrance we use the Kinetic Trajectory Simulation model to obtain the solution to a non-neutral, collisionless plasma sheath. Starting from an initial guess, the potential profile is iterated and our numerical method provides the final time-independent, self-consistent state. It is observed that the sheath structure is highly influenced by varying the temperature.

Key words: Plasma; Quasineutrality; Debyashielding; Sheath; Presheath; Bohm criterion
