-
摘要: 叙述了用金属筒来增强ECR2离子源的高电荷态离子束流强度。铝筒的增强效果最为显著。与锆简相比,Ar(8+)离子的束流强度从245μA增至330μA,Ar(9+)离子从125μA增至150μA。Abstract: The enhancement of charge state ion beam intensities in ECR2 ion source with metal tube is introduced in the paper. The effect of aluminum tube is the most remarkable, it results in Ar8+ ions beam intensity rising from 245 μA to 330 μA, Ar9+ ions from 125 μA to 150 μA in comparison to Zr tube.
