Abstract
A plasma isotope separation process and apparatus. The plasma must be generated and moved into an excitation region for the differential heating of a selected isotope. This motion is accomplished by a crossed magnetic and electric field whereby charged particles move normal to the direction of both fields. The plasma is generated by electrons liberated from hot filaments and the electric field is generated by a plurality of electrodes forming an anode for providing an electric field in a desired direction. An alternating electric voltage may additionally be imparted to the anode to generate an alternating electric field, thereby to differentially excite the isotope of the plasma.
