HIGH FREQUENCY WAVE HEATED PLASMA MASS FILTER

摘要

PROBLEM TO BE SOLVED: To provide a device for effectively generating and maintaining a multi-species plasma in a chamber, and for separating ions in plasma, easy to use and implement.

SOLUTION: A material separator includes a chamber and an electrode to create a radially oriented electric field in the chamber. Coils are provided to generate a magnetic field in the chamber. The separator further propagates a high-frequency electromagnetic wave into the chamber to convert the material into a multi-species plasma. With the crossed electric and magnetic fields, low mass ions in the multi-species plasma are placed on small orbit trajectories and exit through the end of the chamber while high mass ions are placed on large orbit trajectories for capture at the wall of the chamber.
