Ferrite-Free, Oil-Switched, Four-Stage High-Gradient Module for Compact Pulsed Power Applications

Summary form only given. We describe the design and present initial experimental results of a novel, high-gradient, compact pulsed power module. Our application focus is linear accelerators but our technology is easily applicable to a wide range of pulse-power applications. Our design incorporates and combines for the first time a number of our recently developed, enabling technologies including: a novel, bipolar pulse-forming line allowing module stacking without ferrites, very compact and fast oil-filled switches, novel high-dielectric constant insulator/energy storage material, and a novel method for reducing edge enhancements in the pulse forming structure. The combination of these technologies enables us to design a very compact stackable module that will deliver high-gradient (5-10 MV/m) voltage at 5-10kA to arbitrary-loads.
