Plasma supply to the extraction region, which is of essential importance in high-current in sources, is investigated experimentally and theoretically. The theory uses the model that the mechanism of plasma supply is a one-dimensional plasma diffusion, and indicates that the mean free path of ions λ_I and the electron temperature T_e should be large for the effective supply; as an example, √^<λ_I<T_e>≩7 cm・eV^<1/2>. The experiments show qualitative agreement with the theory with regard to the effect of the mean free path of ions on the plasma supply, and indicate that a decrease in plasma density is brought about by beam extraction when the supply is insufficient. The diffusion model used is a simple one, but is thought to be useful for the understanding of ion source performance.
