Since 1998,many experiments for metallic ion production have been done on LECR2(Lanzhou ECR ion source NO.2),LECR3(Lanzhou ECR ion source NO.3)and SECRAL(Superconductiong ECB ion source Advanced design in Lanzhou)at Institute of Modern Physics.The very heavy metallic ion beams such as those of uranium were also produced by the plasma sputtering method,and supplied for HIRFL(Heavy Ion Research Facility in Lanzhou)accelerators successfully.During the test,11.SeμAU~(28+),9eμAU~(24+) were obtained.Some ion beams of the metal having lower melting temperature such as Ni and Mg ion beams were produced by oven method on LECR3 too.The consumption rate was controlled to be lower for ~(26)Mg ion beams production,and the minimum consumption was about 0.3mg per hour.In this paper,the main experimental results are given.Some discussions are made for some experimental phenomena and results,and some conclusions are drawn.
Since 1998, many experiments for metallic ion production have been done on LECR2 (Lanzhou ECR ion source NO.2), LECR3 (Lanzhou ECR ion source NO.3) and SECRAL (Superconduction ECB ion source Advanced design in Lanzhou) at Institute of Modern Physics. The very heavy metallic ion beams such as those of uranium were also produced by the plasma sputtering method, and supplied for HIRFL (Heavy Ion Research Facility in Lanzhou) accelerators successfully. Drawing the test, 11. Seu AU ~ (28+), 9eμAU ~ (24+) were obtained. Metal ion beams of the metal having lower melting temperature such as Ni and Mg ion beams were produced by oven method on LECR3. The rate of consumption was controlled to be lower for ~ (26) Mg ion beams production, and the minimum consumption was about 0.3mg per hour.In this paper, the main experimental results are given .ome discussions are made for some experimental phenomena and results, and some conclusions are drawn.
