A plasma loss to sidewall model for 1D PIC/MCC simulation for plasma transport estimation

Abstract A plasma loss to sidewall model is used for one-dimensional (1D) particle-in-cell (PIC) with Monte Carlo collision (MCC) simulation calculate transport through a transverse magnetic field in negative ion source chamber. The presented 1D includes radial treatment when calculating the axial direction. It does not cost computation effort as much 2D or 3D and can be estimate process quickly. conventional kinetic calculates particle motion only ‘ x ’-direction. y ’ z direction included, leading unusual distribution. Especially applying field, of electrons along line are ignored. Thus completely constrained by resulting abnormal density accumulation. estimation method uses Bohm velocity calculated from parameters obtain flux sidewall. And rate obtained combined chamber geometry. This integrated into self-developed PIC–MCC program examine its effect. Several verification cases performed separately PIC, MCC, module, results exhibit good reliability. Simulations then carried out study across under similar conditions actual experiments. Simulation agree experiment, which indicates that useful dealing
