TL;DR: In this paper, a 2MV Marx generator installed in a completely co-axial form is developed, which reduces the internal inductance down to about 150 nH and makes it possible to produce high intensity electron beams of mare than 20 kA when applied to a field emission type electron gun.
Abstract: A 2MV Marx generator installed in a completely co-axial form is developed. The structure reduces the internal inductance down to about 150 nH hence makes it possible to produce high intensity electron beams of mare than 20 kA when applied to a field emission type electron gun. The rise time of the output voltage pulse is less than 5 nsec.

01 Mar 1974TL;DR: In this paper, the Marx-Bank circuit was used for a flashlamp pumped laser system with a laser medium requiring optical pumping pulses of short duration, fast risetime, and high peak power which uniquely incorporates a low inductance, coaxially configured Marx-bank circuit.
Abstract: A flashlamp pumped laser system having a laser medium requiring optical pumping pulses of short duration, fast risetime, and high peak power which uniquely incorporates a low inductance, coaxially configured Marx-Bank circuit (a multi-stage circuit, each stage having a spark gap and a storage capacitor, with the capacitors being charged in parallel and discharged in series through the spark gaps) characterized by relatively small and inexpensive components and lower dc voltage ratings than those normally in use, whereby pulses of short duration, and high voltage and high input energy can be obtained for driving the flashlamp and whereby problems of insulation and high dc voltage breakdown can be minimized.

TL;DR: In this article, the trigger performance of Marx circuits was investigated and the essential features of an improved circuit were discussed, such as parallel spark gaps PF and firing capacitors CZ in a multi-stage impulse generator.
Abstract: This paper concerns the trigger performance of Marx circuits and shows the essential features of an improved circuit. It is studied how the introduction of parallel spark gaps PF and firing capacitors CZ in a multi-stage impulse generator can improve the trigger performance. Other advantages of the new circuit will also be discussed.

TL;DR: In this article, the laser-tube stray capacity and the time dependent spark resistances of the pulsing system influence the operation of a N2-laser, and an analysis with experimental and analog-computer methods yields an optimum value of the stray capacity.
Abstract: The laser-tube stray capacity and the time dependent spark resistances of the pulsing system influence the operation of a N2-laser. Their analysis with experimental and analog-computer methods yields an optimum value of the stray capacity. In the case of a 40 kV pulse from a 2-gap Marx generator with a 0.4 J energy input we obtain 120 kW laser output with 2.5 ns halfwidth at an optimum stray capacity of 120 pF. A substantially reduced threshold value and increased laser output were observed with a fast single-gap transmission line pulser of the “Nanolite” type.

TL;DR: The design and working principle of a flash x‐ray system and an example for the application of the system in microsecond pulse radiolysis is presented.
Abstract: Design and working principle of a flash x‐ray system is described. A two‐stage Marx generator is used, the charging voltage is 150 kV, the stored energy 1125 J. Anode and cathode are arranged coaxially. The anode consists of a tungsten coated aluminium tube of 20 mm i.d. into which the substances to be irradiated are placed. Measurements of electrical and radiation parameters are described. The x‐ray dose per pulse is 400 rad, the half‐width of the pulse is 0.2 μsec and the mean quantum energy 44 keV. An example for the application of the system in microsecond pulse radiolysis is presented.
