TL;DR: In this article, the breakdown characteristics of solid insulator with two different geometries (a taper insulator and a recessed insulator) are tested under high voltage pulses with different pulse width (90 ns and 140 ns) and the effects of the angle between the solid insulators and the metal electrode and the length of the pulse on the electric field and breakdown voltage have been investigated both by computation and experiments.
Abstract: Summary form only given. The breakdown characteristics of solid insulator with two different geometries (a taper insulator and a recessed insulator) are tested under high voltage pulses with two different pulse width (90 ns and 140 ns). The effects of the angle between the solid insulator and the metal electrode and the length of the pulse on the electric field and the breakdown voltage have been investigated both by computation and experiments. The ANSYS code was used to calculate the electric field between the two electrodes and the gas-insulator-electrode triple junctions. The voltage pulse used for testing is produced by a triggered Marx generator capable of 300 kV output with a rise time of 25 nsec and a pulse length of about 320 nsec. The Marx is made up of six capacitors and three gas insulated three-electrode spark gaps arranged in omega-type. In this arrangement, the gaps can trigger in a wide voltage range from 8 kV to 30 kV and the operation was more reliable. Two different length cables used as pulse form line (PFL) to produce different length of pulses. The measurements show good qualitative agreement with the results from computation.

TL;DR: In this article, the authors designed and constructed a facility to analyze the phenomena associated with high voltage surface flashover of insulators in the low earth orbit environment, which was used to test the validity of models which extend laboratory vacuum-based design principles to include the Earth's upper atmosphere environment.
Abstract: A facility has been designed and constructed to analyze the phenomena associated with high voltage surface flashover of insulators in the low earth orbit environment. The facility incorporates a 10/sup -4/ Torr background vacuum, a low energy plasma, and ultraviolet radiation to simulate the effects of insulator and electrode charging, which are believed to be the main causes of most exterior spacecraft surface flashover problems. Experiments are being conducted to test the validity of models which extend laboratory vacuum-based design principles to include the Earth's upper atmosphere environment. The design and performance of the various sub-systems, including a Marx generator, plasma source, diagnostics, and data acquisition, are discussed in this paper. In addition, the facility's capabilities are presented, with a summary of some of the results generated to date, and an outline of the topics to be investigated in the near future.

TL;DR: AMBIORIX as mentioned in this paper is a high pulsed power generator designed and built by the HPP team of Valduc CEA center in 1985, which is now located in CESTA, a center of CEA near Bordeaux (France).
Abstract: AMBIORIX is a high pulsed power generator designed and built by the HPP team of Valduc CEA center in 1985. This generator is now located in CESTA, a center of CEA near Bordeaux (France). AMBIORIX is formed with a Marx generator (maximum energy storage=300 kJ), water coaxial and triaxial lines. Output parameters are: 0,5 /spl Omega/ impedance; 1.2 MV diode voltage; 2.4 MA load current with a 40 nsec pulse duration. Three kinds of loads can be used: two bremsstrahlung diodes (V max=1.2 MV or V max=400 kV) and a ZPINCH diode. In this paper, the authors describe the generator and give major characteristics of various loads.

TL;DR: In this article, the utility model relates to a high-voltage pulse power supply, in particular to the highvoltage pulses power supply used for algae removal in water, which is mainly used for solving the technical problem that the pulse front edge is greatly influenced by a switch when an existing power supply device is used.
Abstract: The utility model relates to a high-voltage pulse power supply, in particular to a high-voltage pulse power supply used for algae removal in water. The high-voltage pulse power supply comprises an alternating current power supply, a rectification circuit, a Marx generator and a magnetic pulse compression circuit which are sequentially and electrically connected. The high-voltage pulse power supply is mainly used for solving the technical problem that the pulse front edge is greatly influenced by a switch when an existing power supply device is used; and the high-voltage pulse power supply has the advantages of low cost, controllable pulse energy, stability in operation, and the like.
