TL;DR: In this paper, a new kind of solid-state Marx generator based on synchronous transformer type magnetic switches (TTMSs) is put forward, and the TTMSs with new winding structures are used to substitute all the spark gaps in the traditional Marx generator for the purposes of solidification and long life time.
Abstract: In this paper, a new kind of solid-state Marx generator based on synchronous transformer type magnetic switches (TTMS) is put forward, and the TTMSs with new winding structures are used to substitute all the spark gaps in the traditional Marx generator for the purposes of solidification and long life time. As the new type of TTMS with high step-up ratio and low saturated inductances is employed, the proposed Marx generator becomes a compact combination of pulse transformer, magnetic switch, and Marx capacitors. The stages of the Marx capacitors can be synchronously charged in parallel before the magnetic core saturates, and these Marx capacitors also can synchronously discharge in series. The establishing time of the proposed Marx generator is at ns range. As the new type of self-reset TTMS is used, the input voltage of the Marx generator decreases to a low level less than 1 kV while the output voltage can easily reach a high level ranging from dozens of kV to hundreds of kV.

TL;DR: The PBFA-II is a thirty-six module ion accelerator built by Sandia National Laboratories for inertial confinement fusion feasibility studies as mentioned in this paper, and each module is fitted with a SF6-filled gas switch located between an intermediate storage capacitor and the first pulse-forming line (Line 1).
Abstract: : PBFA-II is a thirty-six module ion accelerator built by Sandia National Laboratories for inertial confinement fusion feasibility studies [1]. In the water-filled, pulse-forming section of the accelerator, each module is fitted with a 5.0 MV, SF6-filled gas switch located between an intermediate storage capacitor and the first pulse-forming line (Line 1). The intermediate storage capacitor is charged to 4.8- 5.0 MV in approximately 950 ns by a Marx generator located in the oil section of the machine. The gas switch is required to close on command and transfer the stored capacitor energy to Line 1, a coaxial transmission line of 100 ns two-way electrical length. The switches are triggered by a single 3.0 J KrF laser located under the accelerator; a complex beamsplitting/ distribution system is used to deliver simultaneous 20-40 mJ, 35 ns FWHM beamlets to the individual switches.

TL;DR: The characteristics of the Blumlein pulse power sources developed at the University of Texas at Dallas are reviewed in this article, where the authors show that relatively low charging voltages are multiplied to give the desired discharge voltage without the need for complex Marx bank circuitry.
Abstract: In this report we review the characteristics of the Blumlein pulse power sources developed at the University of Texas at Dallas. These devices consist of several triaxial Blumleins stacked in series at one end. The lines are charged in parallel and synchronously commuted with a single thyratron at the other end. In this way relatively low charging voltages are multiplied to give the desired discharge voltage without the need for complex Marx bank circuitry. Progress in the scaling of these Blumlein pulse generators to obtain open circuit voltages in excess of 0.5 MV is described. Application of these devices to produce high power x-ray pulses is discussed.

TL;DR: In this article, a new trigger method based on the superposition of an additional voltage pulse to the charging voltage in a two-electrode spark gap configuration has been developed.
Abstract: Triggered Marx-generators running in repetitive operation play an important role for many future industrial applications replacing the traditional methods for the treatment of large mass streams. A reliable operation over a fairly long time is one prerequisite, the design of such a generator has to guarantee. For conventionally triggered spark-gaps we experienced a comparatively short component lifetime. Therefore, a new trigger method based on the superposition of an additional voltage pulse to the charging voltage in a two-electrode spark-gap configuration has been developed. The paper describes the implementation into an existing Marx- design and some preliminary experimental results.

TL;DR: This paper focuses on compact linear Marx generators, which are frequently constructed in close-fitting metallic housings and can deliver fast rising and nominally flat pulses into resistive loads.
Abstract: Compact high-voltage Marx generators have found wide ranging applications for driving resistive and capacitive loads. Parasitic or leakage capacitance in compact low-energy Marx systems has proved useful in driving resistive loads, but it can be detrimental when driving capacitive loads where it limits the efficiency of energy transfer to the load capacitance. In this paper, we show how manipulating network designs consisting of these parasitic elements along with internal and external components can optimize the performance of such systems.
