Microsecond-pulse insulation and intense ion beam generation in a magnetically insulated vacuum diode

Abstract: The insulation and ion generation characteristics of coaxial magnetically insulated diodes were tested using microsecond voltage pulses from a Marx generator with magnetic fields ranging up to 20 kG, voltages of 150–300 kV, and gap widths of 0.3–0.9 cm. Voltage standoff was observed for up to 4 μsec when using graphite or metallic electrodes. With plasma‐producing nylon filament anodes, high‐energy ion beam pulse lengths of up to 2 μsec and total charge generation densities of up to 7.5 μA sec/cm2 were obtained.

Magnetically insulated linac driven by a multistage Marx generator

Abstract: It is shown that a magnetically insulated linear accelerator driven by a multistage Marx generator can accelerate over short distances intense beams of heavy ions to multi-GeV energies. The attainable beam energies are sufficient for the ignition of thermonuclear microexplosions. The proposed accelerator could also ideally serve as a research tool for heavy ion induced nuclear reactions.

Efficient flashlamp-pumped UV dye laser driven by a Marx-bank generator

Abstract: An efficient flashlamp-pumped UV dye laser driven by a four-stage Marx-bank generator with fast rise time is reported. An output energy of 25.2 mJ (420 kW) for 81.5-J input energy is obtained in a p -terphenyl dye laser at 3426 A. Output energy and laser efficiency increase remarkably by increasing the number of stages in the Marx-bank driver without spoiling its fast rise time.
