摘要
LECR2 (Lanzhou ECR ion source No. 2) had been run for HIRFL accelerator on-line service for more than 6 years. This source had delivered very high charge state ion beams like Xe27+ , Ar14+,etc. to HIRFL accelerators for many times and greatly enhanced the performances of HIRFL accelerator complex, and had also produced many kinds of intense metallic ion beams to make the acceleration of metallic ion beams pos-
