The improved isotope separator comprises a vacuum vessel, a plasma generator located substantially in the center of the vacuum vessel, an electrode bounded by a hyperboloid of one sheet and a pair of electrodes bounded by a hyperboloid of two sheets, said electrodes being located within the vacuum vessel in such a way as to surround the plasma generator, a power source for supplying said electrodes with a fixed voltage and a pulsating voltage, and magnetic field generating means located outside the vacuum vessel. The apparatus is implemented by a method for isotope separation that achieves high separation factor per stage (process), that enables the process throughput to be increased with ease and which yet is applicable to the isotopic separation of many elements.

The present invention pertains to a Fresnel lens type complex reflecting system in which a set of parabolic mirrors are utilized to function as a convex lens. This is accomplished through incident light rays impinging on concave surfaces of the parabolic mirrors. In this way, the focal point of the complex reflecting system will be on an opposite side of the complex reflecting system as the direction of incident light. Another feature of the present invention is an orientation of a set of parabolic mirrors which function to operate as a concave lens. This is accomplished through incident light rays impinging on convex surfaces of the parabolic mirrors.
