TL;DR: In this article, a series of experiments designed to measure the flashover strength of various azimuthally symmetric $45\ifmmode^\circ\else\text degree\fi{}$ vacuum-insulator configurations was conducted.

TL;DR: In this article, the design of a 6.5-MV linear transformer driver for flash-radiography experiments is presented, and several fault modes are identified, and circuit simulations are used to determine their effect on the output pulse and other components.

TL;DR: The radiographic integrated test stand (RITS) as discussed by the authors is an adder system designed specially to drive a 10-MV diode immersed in magnetic fields as high as 50 T. In this diode, an electron beam of tens of kiloamperes can be confined by the magnetic field to a diameter of about 1 mm, and when it strikes a high-Z anode, it can create a bremsstrahlung X-ray source intense enough to radiograph massive objects with high resolution.

TL;DR: Hermes III as discussed by the authors is a 22-MV, 730-kA, 40-ns pulsed power accelerator that drives an electron beam diode/converter to generate an intense pulse of bremsstrahlung radiation.

TL;DR: In this paper, a 16 MV, 50 ns flat-top voltage adder has been designed that is optimum to develop radiography diodes in which a <1 mm diameter cathode is immersed in a 60 T magnetic field and pulsed to /spl sim/16 MV.
