Compulsators (Compensated Pulsed Alternators) are AC generators which are used for the electromagnetic launch (EML) applications over the last few decades. Passive compulsator consists of a compensating shield which is placed in the vicinity of the armature conductors. In the present work, a passive compulsator has been designed to drive a railgun which was built and tested with a capacitor bank of 20 kJ in the author's laboratory. The effect of variation of the thickness of the compensating shield on the performance on the system is discussed in this paper. Performance analysis is done for a number of designs with different thickness of the compensation shield, out of which, two designs were selected, modeled and analyzed with a commercially available FEM based package. Only electromagnetic and electromechanical effects are considered in this paper.

In this paper a voltage droop compensation based on a resonant circuit is proposed for the optimized solid-state bipolar Marx modulator. Keeping the modularity characteristics and the circuit topology, one auxiliary resonant stage was added to the existing Marx stages. The compensation concept consists of adding the auxiliary voltage to the output positive or negative pulse for voltage droop compensation. Simulation results are presented for five stages Marx circuit, 10% voltage droop, using 800 V per stage, 100 ps pulse duration at 50Hz frequency.

Disruption is a big problem for existing tokamak-path MCF and the paper explore a new ignition path with low-current-fusion (LCF) by high-gain high-field (HGHF) plasma suggested in Ref. [1. Li G., Sci. Rep. 5, 15790 (2015)]. Disruption risk could be mitigated easily due to the low current implementation at about 2–3 MA at large aspect ratio A >2 for better engineering implementation.

Our team at Los Alamos National Laboratory has successfully employed Compton spectrometers to measure the x-ray spectra of intense radiographic sources, both continuous and flash. In this method, a collimated beam of x-rays incident on a convertor foil ejects Compton electrons. A collimator may be inserted into the entrance of the spectrometer to select the angular acceptance of the forward-scattered electrons, which then enter the magnetic field region of the spectrometer. The position of the electrons at the magnet's focal plane is proportional to the square root of their momentum, allowing the x-ray spectrum to be reconstructed. Two spectrometers have been fielded since 2013; a neodymium-iron-boron permanent magnet with an energy range of 500 keV to 20 MeV, and a new samarium-cobalt magnet with an energy range of 50 keV to 4 MeV. Measured spectra were produced by x-ray generating machines of various intensities (~5 rad at 1 m per 50 ns pulse to >2000 rad/min at 1 m) and different endpoints (range of 2.25 to 20 MeV). Preliminary analysis of the electron spectra produced at two different facilities with various beryllium converter foil thicknesses is presented in these proceedings.

Nowadays, water pollution is one of the environmental problems. We have studied a sewage treatment using nanosecond pulsed power discharges. The water treatment utilizes not only active species such as hydroxyl radical produced by electric discharges but also direct actions of discharges such as ultraviolet rays, shock wave and so on. In order to reduce the costs for treatment, treatment using air gas as a discharge gas was studied. The treatments using streamer discharges in simulated air gas, consisting of 20 % oxygen and 80 % nitrogen, and oxygen gas were evaluated. The surfactant treatment was assessed by the height of foam in the reservoir, which was one of the characteristics. The treatment by oxygen as discharge gas continued to reduce the height of foam in reservoir for 80 minutes treatment. On the other hand, the foam decreased rapidly for 0–20 minutes treatment. Under the presence of NO2, height of foam decreased rapidly because of increasing OH radical production. However, after 20 minutes, decrease of height of foam became slow because OH radical was consumed oxidizing NO2.

There is a strong demand in the power and pulsed power industries to find potential environmentally friendly alternative gases and liquids with advanced dielectric properties with the aim of replacing of SF6 gas in high-voltage equipment due to environmental concerns. Several alternative gases such as CF3I and hydrofluoroolefin and the mixture of these gasses with buffer gases have been considered as potential substitutes for SF6. However, the breakdown properties of these gases and gas mixtures are not well understood and their characteristics require further investigation in order to establish and expand potential practical applications. In this paper, the breakdown behaviour of gasses with well-established characteristics (air, CO2, N) and those of hydrofluoroolefin HFO1234ze/CO2 gas mixtures have been obtained in a dedicated point-plane topology, under the positive and negative voltage stress. The gas pressure in the test cell was in the range from 1 bar to 10 bar (abs) and all tests were conducted at room temperature. The obtained breakdown and corona ignition voltages will help in further development and optimisation of the plasma closing switches operating in the corona stabilisation regime and filled with environmentally friendly gases.

Pulse Transformers are used in pulse power generating system when Output Voltage is to be raised, to invert the polarity and provide a DC isolation between discharging source and Load with minimum loss of energy and maximum transformation efficiency. Among different kinds of high-voltage pulse transformers, authors have studied Pulse Transformer with closed magnetic core. Studies are made with pulse transformer with different geometric structure of transformer windings and considerable impacts on the output characteristics has been observed. Authors also studied the effect of auxiliary windings on the pulse shape of a closed magnetic circuit-type high-voltage pulse transformer.

For discrete semiconductor switches with smaller ratings stacked for high-voltage high-current applications, there is the need to ensure reliable gate synchronization of all the switches in the stack. The switching delay between the separate stages can be minimized through fast transfer of the control signals needed for synchronizing the switch or by reducing the effects of stray inductances. This paper describes the design of a HV switch which uses the inductive energy stored in the primary transformer for switch synchronization. In this design, single low-voltage power source provides control signal and sufficient current to drive the stacked insulated-gate bipolar transistors (IGBTs) at a sufficiently high gate — emitter voltage. The fast current transfer due to this inductive energy greatly improves switch turn-on delay time, allowing for reliable switch synchronization at fast speed. The designed HV switch was used as the modular unit of an SSPPM to apply rated pulse output voltage and current of 15 kV and 1.5 kA respectively to a load. The operation of the designed HV switch was verified through experimentation.

This paper proposes a dual-line closed transition transfer switch (CTTS) and a technique for fault and lifetime self-diagnosis. The proposed system consists of the dual-line CTTS, a closed transition operator, active and inactive channel inspectors that extract the switch characteristics, and a self-diagnosis block for fault and lifetime of the switch using the characteristics. The system controller coordinates the inspection and diagnosis based on a schedule. The proposed dual-line CTTS and self-diagnosis were verified by the PSIM simulator. The closed transition was successful although the frequencies of the two sources were different. During the inspection using the current and voltage of each phase, the signal variation was detected fast so the switch characteristics and even fault problem were detected fast as well.

The Spallation Neutron Source (SNS) utilizes an electron scanner in the accumulator ring for nondestructive transverse profiling of the proton beam. The electron scanner consists of a high voltage pulse generator driving an electron gun, a medium voltage ramp generator, and a CCD camera. A new high voltage pulse generator that provides negative 100 kV pulses with rise times of less than 200 ns, +/−0.5% flattop of greater than 100 ns has been designed, delivered, and undergone extensive testing. The pulse generator has been operationally verified with the existing control system and simulated loads. Full system testing with the actual electron scanner is planned. This paper details the requirements, design, setup, and test results of the high voltage pulse generator.
