A NEW ION SOURCE FOR ELECTROMAGNETIC ISOTOPE SEPARATORS
A versatile, high-resolution, electron-impact ion source for electromagnetic isotope separators is described. In contrast to conventional ion sources, the performance is excellent over a very wide range of operating conditions. The source efficiency is high and the extracted ion beams appear to be virtualiy hash'' free. A resolving power of over 13,000 and isotopic enhancement factors of from 10,000 to 30,000 were obtained at outputs of over one milliampere with a variety of elements. Such enrichments are from ten to several hundred times better than those obtained under similar conditions with other sources. The behavior of the source with a number of stable elements and with plutonium is described in detail. The use of carbon as an alternative source filament material is described. (auth)
