“…The reason that we introduced the solid-state IMG and not use a solid-state LTD or regular solid-state Marx generator is the rise time. The IMG is capable of generating extremely fast pulses due to its impedance-matched design (for more details, see [38]) and is therefore ideally suited for efficient pulsed streamer discharge generation. The only downside to the IMG when considering arbitrary waveform generation is that if it is perfectly impedance-matched, using a scheme as in figure 1 will introduce pulse reflections that will (slightly) distort the waveform (because we violate the impedancematching criterion concerning triggering).…”

“…To generate arbitrary waveforms with pulsed high-voltage sources, such sources make use of a multi-stage topology, such as the Marx generator [43], the LTD [44] or the recently introduced IMG [45]. As mentioned in the introduction, of each of these topologies there are now solid-state versions [35,36,38]. The way in which such topologies can generate arbitrary waveforms is by independently triggering the stages and then the topology ensures that the output of these linearly add to the output waveform.…”

“…While such pulse sources can generate arbitrary waveforms, they typically have a relatively slow rise time (10-20 ns at best) and we need the fastest possible rise time (ideally less than several nanoseconds) for high-yield plasma processing. Therefore, we introduced a new solid-state pulse topology capable of both fast rise-time pulses and arbitrary waveforms: the solid-state impedance-matched Marx generator (IMG), which was described in detail in [38] and of which a brief concept and a description of its capabilities will be given in section 2. In this paper, we will show the first results of pulsed streamer discharge generation with the arbitrary waveforms from a solidstate IMG.…”

In this paper we present our solid-state nanosecond pulse source (the solid-state impedance-matched Marx generator) which can generate arbitrary waveforms and which can be used for pulsed discharge generation. The purpose of the development of such a generator is twofold: by being able to change the waveform at will, we aim to control the discharge generated by such pulses very precisely which can be very useful for plasma applications, but also for more fundamental studies. In the presented study, we applied the arbitrary-waveform pulse source for streamer discharge generation in a cylinder-wire-like arrangement and used the arbitrary-waveform capability to change the rise time (in our experiments we used 6.8-26.2 ns) of unipolar positive pulses with 6-10 kV amplitude and 80 ns duration. Additionally, we introduced variations of a step in the rising edge of the waveform. We performed measurements both in air and nitrogen to electrically characterize the discharge while analyzing the streamer propagation in the plasma reactor with intensified charge-coupled device imaging and measured ozone generation (in air). The results show that we can indeed control the propagation of the streamer discharge with the stepped waveform, but that the rise-time variation has little effect on the streamer propagation in our system. However, the streamer velocity and structure differs significantly comparing discharges in nitrogen and air for the same applied voltage waveform. Additionally, for some of the stepped waveforms we found a slight increase of the ozone yield for air at low overall energy densities.

“…The more detailed studies of impedance matching in more complicated Marx generators and their characteristics are provided in Ref. [3], [12], [13]. The biasing voltage of V g = 23 V is sufficient for periodic self-triggering of the Marx circuit without an external generator with a repetition rate of 1.5 − 2 M Hz determined by the bias voltage and…”

In this paper, we have studied the temporal evolution of switching for each stage of the Marx generator with picosecond temporal and millimeter spatial resolutions employing terahertz measurements. The Marx circuit utilizes collapsing-field-domain (CFD)-based avalanche switches, which are formed in a bipolar GaAs structure and result in the picosecond speed of powerful carrier generation and electrical switching. The application of the CFD-based avalanche switches emitting mm-wave pulsed radiation in the Marx generator provides a unique opportunity to accurately track the switching instants for each of the circuit stages with a picosecond time precision. The collapsing domains cause the sub-THz pulses radiated by each of the avalanche switches, and the same domains generate the electron-hole plasma thus causing simultaneously the electrical switching. In this work, we report the direct measurements of the switching instants for each of the four stages Marx generator and suggest an interpretation of non-trivial experimental results.

Streamer discharges generated by nanosecond high-voltage pulses have gained attraction for a variety of reasons, but mainly because they are very efficient for a number of plasma-processing applications. More specifically, researchers have noted that the pulse duration and the rise time of the applied high-voltage pulse have a significant influence on the radical yield of the transient plasmas generated with these pulses; shorter pulses result in higher yields. With the need to study transient plasmas generated by these short pulses comes the need to understand how to generate those pulses and to understand the interaction between the pulse source and the discharge. In this topical review, we will explore the different methods with which to generate nanosecond highvoltage pulses, how the interaction between the pulse source and the discharge may influence the source and the discharge and how to optimize the energy transfer from the pulse source to the discharge.
