【Abstract】 This paper describes a newly designed side extraction PIG ion source which possesses magnetic mirror field produced by a permanent magnet. The advantages of the source are: uncomplicated structure, light and handy, and low power dissipation. It also has the characters of larger densities of extracted beams and higher proportions of atomic and multiple charged ions. Under the condition of 50-150W arc power, 1,0 mA extracted beams were obtained for H, BF, and Ar, in which the proportions of H, N and B are 90%, 70%, 50% respectively. B, N, Ar are also observed.更多还原
