Operation of rf ovens in ECR ion sources
Review of Scientific Instruments, 2004 A 34-mm-diam rf oven system previously developed on bench [Cavenago, Kulevoy, and Petrenko, Rev. Sci. Instrum. 73, 552 (2002)] was inserted and tested into the electron cyclotron resonance (ECR) ion source Alice, producing beams from natural copper and silver samples; charge range was typically i=10–14 for copper and i=10–19 for silver, which compares ...
