Stephen E Sampayan, George J Caporaso, Hugh C Kirbie: Enhanced dielectric-wall linear accelerator. The United States of America represented by the Department of Energy, William C Daubenspeck, William R Moser, Paul A Gottlieb, September 22, 1998: US05811944 (86 worldwide citation)

A dielectric-wall linear accelerator is enhanced by a high-voltage, fast e-time switch that includes a pair of electrodes between which are laminated alternating layers of isolated conductors and insulators. A high voltage is placed between the electrodes sufficient to stress the voltage breakdown o ...

Stephen E Sampayan, Monroe L King, Robert A Moore: Ion source. Eaton Corporation, F M Sajovec, July 26, 1988: US04760262 (11 worldwide citation)

An ion source (10) of the side-extraction hot cathode type in which the inherent drift of electrons toward the positive side of the cathode is minimized by the addition of auxiliary electrodes (31, 32) which surround the cathode (14) at the ends of the anode (12). The electrodes are electrically iso ...
