Characteristics of Co-Axial Marx Generator and Its Application to Electron Beam Fusion

Abstract: A co-axial Marx generator with a short rise time of pulse less than 4 nsec, and ~40 nsec flat top duration was successfully constructed. For the attainment of electron beam fusion, the requirements for the beam source are a rise time of less than 1 nsec, an impedance of less than 0.01 Ω and an inductance of less than several nH/MV. The co-axial Marx generator can be considered to be the most important tool for these purposes. We analyzed this rectangular output pulse of the co-axial Marx generator and applied it to electron beam fusion.

A high-power TEA N2 laser using a modified Marx generator

Abstract: A new design of TEA N2 laser for producing high-density excitation by combined use of a modified Marx generator and a pair of high-speed capacitors is described. Laser output of 1.5 MW (1.2 mJ, 0.8 ns) is obtained from a 12 cm long uniform discharge at a charging voltage of 25 kV.

A Study of the Double-Focusing Diode

Abstract: Applying a co-axial Marx generator with rectangular pulse across a constant load for the study of double-focusing-diodes, an impedance reduction and an increase in anode plasma density are observed. To achieve electron beam fusion, low-impedance diodes of impedance less than 1 Ω have been researched. The reduction of impedance accompanied by electron-beam double-focusing is important. It may be speculated that electron reflexing after focusing is required to lower the impedance and to increase the anode plasma density.

Microsecond-Pulsed Ion Beam from a Marx Generator

Abstract: We have maintained Langmuir-Child bipolar flow at a peak voltage of 650 kV in a vacuum diode for 1 ?s without gap closure or electrical breakdown of the diode insulator. An ion current of > 300 A (> 7.5 A/cm2) was extracted from the diode in a beam having a large component of divergence < 10-2 rad.
