“…The operation requirement of the GaAs PCSS, the design parameters of the high gradient insulator, the transport of the charged particle beam, and the assembly of the whole accelerator were taken into consideration during the design of the SPTL. 11 The SPTL was tested under highvoltage pulse with micro-second rise-time in the transformer oil, and the results show that the maximal breakdown strength is above 55 kV/mm.…”

Compact solid-state system is the main development trend in pulsed power technologies. A compact solid-state high-voltage nanosecond pulse generator with output voltage of 300 kV amplitude, 10 ns duration (FWHM), and 3 ns rise-time was designed for a dielectric wall accelerator. The generator is stacked by 15 planar-plate Blumlein pulse forming lines (PFL). Each Blumlein PFL consists of two solid-state planar transmission lines, a GaAs photoconductive semiconductor switch, and a laser diode trigger. The key components of the generator and the experimental results are reported in this paper.

“…In previous studies, a compact solid-state 300 kV nanosecond pulse generator with 15 stages stacked planar-plate Blumlein pulse forming lines had been established for a dielectric wall accelerator which operated in single mode. Some key technologies were depicted in detail in our previous articles [12][13][14]. The pulse generator was just working like a Marx circuit configuration which all the pulse forming lines were charged in parallel and subsequently fast discharged in series.…”

Non-equilibrium plasma is a promising technology for the generation of ozone and removal of exhausted fuel gases. However, applications of non-equilibrium plasma are restricted by energy utilization efficiency in many industry fields. Discharge excited by nanosecond pulsed power is regarded as one of the most efficient methods. In this study, a compact 5 stages stacked blumlein pulse forming line and photoconductive semiconductor switches-based power source was introduced to generate pulsed plasma. This compact source could achieve over 50 kV with 10.1 ns pulse width and 4.8 ns pulse rising time. Coaxial cylindrical reactor was employed to generate a pulsed streamer discharge driven by the nanosecond pulsed source in atmospheric pressure air. Electrical parameters of the streamer discharge have been obtained in this study, the instantaneous power dissipation exceeds 8 MW and the average energy consumption of each pulse exceeds 56 mJ. Experiments of high speed photography have been conducted to observe the evolution process. It can be found that streamer heads start from the central wire electrode and then head to the grounded cylinder electrode in all radial direction of the coaxial electrode. Triple wire-to-cylinder electrodes discharge shows that all the three coaxial discharges develop synchronously and symmetrically, which shows that is capable of generating large volume non-equilibrium diffusive streamer discharge plasma.
