Component Design, Development, and Testing of an Inductive Voltage Adder (IVA) System for Jupiter.

摘要

Jupiter is a proposed 15-20 MJ laboratory x-ray source. It would store ~ 100 MJ in the Marx generators and deliver ~ 500 TW to drive high power z-pinch implosions. The pulsed power requirements for Jupiter were evaluated by a national review panel1 which concluded that the modular IV A technology as used in HERMES III2 is capable of meeting these requirements. Modularity of construction permits design verification with less than a full size system and offers the flexibility to meet changing requirements. A program to validate this approach at the required power levels has begun with the construction and testing of components that will comprise a full scale IV A generator module. The IV A module will provide a nominal 10 MV, 1.8 MA, 100 ns FWHM output pulse and will consist of four submodules. Each submodule is composed of a Marx generator, two Intermediate Energy Storage Capacitors (ISCs) four Pulse Forming Lines (PFLs), one Voltage Adder Cavity (VAC), plus other associated switches and hardware. A conceptual design for this IV A module has been completed. Initial designs for the ISC, PFL, and their gas switches are also complete and hardware has been procured. Testing of these components is underway at Sandia National Laboratories. Discussions of these designs and results of tests are presented in this paper.
