Apparatus for Isotope Separation by Thermal Diffusion

Abstract
A compact, all‐metal, multi‐stage thermal diffusion apparatus for the separation of isotopes in quantity in non‐corrosive gases at any pressure up to 175 lb/in.2 is described. For a particular gas the proper pressure may be well‐enough calculated in advance as that giving maximum separation factor in the last column only. Operating with neon at 3 atmos. pressure, and using 12 meters of column consuming 4.9 kw for 260 hours, 7 liters of gas with a Ne22 content of 93.4 percent were produced.
