Abstract:
This article describes a new type of radio-frequency metal ion source, which can be operated with gases, liquids and solids. The operating temperature of the ion source may reach 1000℃. Therefore we can extract ion beams of a considerable number of the elements including metal. At present, the ion beams of Al+, Mg+, Fe+, Cr+, Zn+, In+, Ag+, Cd+, Sn+, Sm+, Hg+, S+, P+, As+, Se+, Te+, etc. have been extracted. The total beam current ranges from several hundred microamperes to the order of milliamperes. The useful fraction of ion in total beam is 70—90%. The life of the source ranges from 40 to more than 100 hours.The basic structure and operating characteristics of the source are mainly discussed in this paper.
