A sheath model in an oblique magnetic field is build, which has one-dimension coordinate space and three-dimension speed space. The effects of magnetic field on the structure of RF sheath and parameter characteristics are discussed. The numerical simulation result shows that magnetic field has great effects on the sheath structure, especially in the region near the edge of sheath. Also, the magnetic...
A pulsed voltage of magnetically insulated diode and intense pulsed ion beam (IPIB) models have been built according to the experimental results. A model of secondary electrons yield while IPIB irradiated metal target has also been established. The temporal law of secondary electrons induced by IPIB irradiated titanium target according to the energy deposition at surface layer has been calculated...
The effect of erosion structure of the wall surface on near wall conductivity was studied in this paper. The electron dynamics process in the plasma was described by the test particle method where electrons were randomly injected into the wall. Monte Carlo method was used to calculate the model. The simulation results showed that the axial current density increased in the case of erosion. Furthermore,...
The characteristic of dust plasma sheath in an oblique magnetic field was studied using the fluid method. In a magnetic field of various magnitude and directions, the charged dust density distribution has been discussed. It is shown that magnetic field does have effect on the dust characteristic. The action of electrostatic, gravitational force and Lorentz force make the dust grains do a helical movement...
The structure of the plasma sheath in an oblique magnetic field with the fluid method was investigated. In various magnitude and directions of the magnetic field, the electron and ion density distribution, ion flow velocity, electron potential and Bohm's criterion have been calculated. It is shown that magnetic field has obvious effect on the plasma sheath. Under the action of electrostatic and Lorentz...
