The work will present the most recent phase in the development of a GW-class pulsed power generator intended for medical and biological applications. Based on a Tesla transformer charged Blumlein pulse forming line, the generator output is connected to a bipolar former capable of producing approximately sinusoidal 1 GHz, 600 kV peak-to-peak voltage impulses. The bipolar output feeds an...
It is known that the properties of pulsed current filaments can affect the efficiency of ozone generation[1]. In this paper, a statistical analysis was made to investigate the properties of the current filaments observed in dielectric barrier discharges with meshed electrodes. Two stainless-steel sheets with 0.96 mm apertures were used as the meshed electrodes. A 5 kHz smart power supply was...
Powerful dynamic shock waves induced by pulsed discharge in water has been widely adopted in many industry applications, such as material processing, rock fragmentation, electrohydraulic cleaning, high intensity ultrasound source, et al. It is necessary to research on how to induce shock waves steadily and efficiently. An experiment stand of pulsed discharge is designed and constructed, based...
Many industrial-scale electroporation devices are driven by Marx generators. Thereby, the pulse circuit comprising the Marx generator and the electroporation reactor needs to be tailored specifically to the requirements of the application. Biological material for electroporation-assisted extraction processes is treated at pulse lengths on the order of several microseconds. For large-scale...
Plasma in contact with water has been widely investigated for the production of reactive species such as H2O2 and OH radicals [1]. In this research, both positive and negative pulsed corona discharges, with duration of the order of microseconds, were used to investigate hydrogen peroxide formation in a pin-to-water electrode system.
Under positive pulsed corona discharge, hydrogen peroxide...
A very important topic in the field of electromagnetic accelerators of the railgun-type is the realization of an appropriate power supply. So far, three different ways of storing energy for railguns have been explored: electric fields, magnetic fields and kinetic energy corresponding to capacitors, storage coils and fly wheels respectively. The project to be presented here and funded by the...
The CLIC study is investigating the technical feasibility of an electron-positron collider with high luminosity and a nominal centre-of-mass energy of 3 TeV. The pre-damping rings and damping rings (DRs) will produce ultra-low emittance beam with high bunch charge. To avoid beam emittance increase, the DR kicker systems must provide extremely stable field pulses during injection and extraction...
Plasmas exhibit properties that make them useful in a wide range of applications, such as lighting, semiconductor processing, nanometer lithography, surface treatments, fusion energy, plasma medicine, future fuels, plasma agriculture and environmental applications. Within this large area, pulsed-power driven, transient plasmas perform much better in energy efficiency and processing...
