Abstract (en)

[origin: WO0057452A2] 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.
