The Study of Kinetic Energy of Ion and Sheath Thickness in Magnetized Plasma Sheath

Abstract

Abstract:In all plasma applications, sheath formed in front of a material wall is responsible for the flow of particles and energy towards the wall. The kinetic energy of ion and sheath thickness in magnetized plasma sheath region has been numerically investigated by using a kinetic trajectory simulation model for different magnetic field and its obliqueness. It has been revealed that, the kinetic energy of ions reaching the material wall can be controlled by the strength of applied magnetic field and its orientation. Kinetic energy of ion increases when we move towards the wall, whereas the kinetic energy of electrons decreases as expected, which becomes prominent as the strength and obliqueness of the field increase. It is found that by increasing the magnetic field strength, there is an increase in the ion energy and a decrease in the sheath thickness.
