TL;DR: In this paper, a compact high-voltage controllable Marx generator is presented, which comprises a charge power supply, a charge resistor, a sphere-gap trigger switch, a withstand voltage capacitor set, capacitors, spark switches, 2N resistors and steep gaps.
Abstract: The invention discloses a compact high-voltage controllable Marx generator which comprises a charge power supply, a charge resistor, a sphere-gap trigger switch, a withstand voltage capacitor set, (N-1) capacitors, (N-1) spark switches, 2N resistors and steep gaps, wherein the charge resistor, the sphere-gap trigger switch, the withstand voltage capacitor set, the capacitors, the spark switches and the resistors are all arranged in a sealed metal barrel; the sealed metal barrel is filled with mixed gas of liquid nitrogen and sulfur hexafluoride; the steep gaps are used for outputting steep leading edge high voltage pulses. The compact high-voltage controllable Marx generator is high in reliability, small in size, steep in pulse high voltage leading edge and low in construction cost.

TL;DR: The RAPIER B Amplifier electron beam system has been completed and produces 36kJ of 450 keV electrons in a 150 ns pulse to be used for pumping a KrF laser amplifier as mentioned in this paper.
Abstract: The RAPIER B Amplifier electron beam system has been completed and produces 36kJ of 450 keV electrons in a 150 ns pulse to be used for pumping a KrF laser amplifier. The operating characteristics of the system have been studied. The efficiency of conversion of energy stored in the Marx generator to electron beam output is 72 +- 3% including an 89% designed transfer efficiency. The system is triggered electrically with a 150 ns delay from the command trigger to machine output. The rms jitter for the six individual modules range from 1.6 to 3.9 ns and the average timing difference between the earliest and latest module output is 12 ns. Film dosimetry indicates no observable interaction between the magnetically isolated beams in the module diodes and fluorescence measurements do not indicate strong interaction in the gas filled laser cell. Current probe measurements show no significant change in beam size during the output pulse. Energy deposition profiles agree reasonably with Monte Carlo calculations up to pressures of 1.5 atm.

TL;DR: In this article, the Marx generator with stages based on artificial long lines with matched loads connected to them was used to obtain high-power microsecond electron beams with high energy using an electron beam source with an explosive emission cathode and a plasma anode.
Abstract: Experiments have been carried out to obtain high-power microsecond electron beams with high energy using an electron beam source with an explosive emission cathode and a plasma anode. The beam was formed and transported in a longitudinal magnetic field. The voltage source was the Marx generator with stages based on artificial long lines with matched loads connected to them. The possibility of realization of operation modes of the electron beam source with quasi-constant values of the accelerating voltage and current without highcurrent arc discharge formation in the interelectrode gap is demonstrated. Electron beams with circular and rectangular cross sections of ~100–200 cm2 with current up to 1–1.5 kA and duration of 5 μs were obtained at a quasi-constant accelerating voltage of 200 kV. The rotation of the beam around its axis was recorded. The possibility of electron beam extraction through a foil window into the atmosphere has been tested.

TL;DR: In this article, the authors have developed a reliable and easy to carry compact 4-stage Marx generator that can produce impulse voltage 4 times of input voltage with some minor losses, which is useful in small scale industries and academic institutions to demonstrate impulse voltages.
Abstract: This paper shows the development of a reliable and easy to carry compact 4 stages Marx Generator that can produce impulse voltage 4 times of input voltage with some minor losses. In addition, three different experimental circuits of DC supplies have been made. The highest output was 100 V DC for which input was taken as the main supply for the experimental and simulated Marx generator circuit. This generator is useful in small scale industries and academic institutions to demonstrate impulse voltages and also to perform testing on insulators and transformers of lower rating in laboratory. A total of 4 stages of both simulated, experimental Marx impulse generator circuit is designed and the impulse waves are recorded. The simulated recorded impulse waveform, is compared with the standard impulse wave. Both of circuits, the efficiency of each stage was calculated and the percentage of error in the front and tail time was also found out as well as the effects of the circuit parameters on the impulse waveform characteristics were also studied. The simulation was done with the help of Proteus 8 Professional. In this work, the comparison in terms of magnitude of the experimental and simulated 4 stages Marx generator circuit has been carried out.
