Abstract
The commercial purification of He3 as well as that of other stable rare-gas isotopes has generally been performed in thermal-diffusion columns since the inception of the USAEC stable-isotopes separation program [1]. While thermal diffusion is a relatively straightforward method of isotope separation, it is inefficient in that it requires large quantities of electrical power. A single thermal-diffusion column may be 8 m long, and several columns must be cascaded in order to produce the desired separation.
