CORRUGATED STYLE ANODE ELEMENT FOR ION PUMPS

摘要

An ion pump anode eliminates the intercellular spaces while maintaining an efficient cell shape in which the plasma sheath follows the contour of the cell wall. The cells are preferably quasi-cylindrical and can be manufactured by folding one or more metal strip into a corrugation and welding the strip to create separate cells. By eliminating the intercellular region, which supports a high plasma density, the formation of dendrites under such a region is prevented and instabilities caused by those dendrites are eliminated.
