The new separation principle of neon-helium mixture is presented. Mixture is precooled in steps to helium temperatures (about 10K) under low pressure (1 ... 2 bar) and then the one is condensed on the special tube surface with high contact area. Neon is extracted from the mixture in the solid phase without liquid phase that allows to receive high purity gas (neon 99,997%). The pilot unit based on this principle is described. The unit production possibility is 1m per hour.
