A cascade with a total length of 18 m consisting of six glass columns with a hot wire down the middle was constructed to produce 90% Ne/sup 22/. The average thermaldiffusion separation coefficient was 0.03; the temperature of the refrigerant was 280 deg K; the working pressure was 750 mm Hg; the diameter of the hot wire was 0.03 cm; the initial concentration of Ne/sup 22/ was 10 at.% and the required concentration was 90 at.%. The internal diameter of the six consecutive sections of the column was reduced gradually for each section from 2.9 to 1.1 cm in order to decrease the time required in attaining steady-state operation. It required 15 days to reach steady-state. The maximum concentration of Ne/sup 22/ was 99.97 at.%, while the over-all separation factor for the cascade was approximately 6 x 10/sup 4/. Withdrawal of 90% Ne/sup 22/ can be made at the rate of 200 cm/sup 3// day with a concentration of 4 to 5 at. % Ne/ sup 22/ in the rejected portion (at an initial concentration of Ne/sup 22/ of approximately 9.9 at. %).
