Abstract
We present the results of simulation of the initial breakdown stage of a high-voltage nanosecond discharge (HVND) in air at atmospheric pressure in a gap with a sharply inhomogeneous electric-field distribution. The simulation was based on an established relation between the discharge-gap capacitance upon streamer formation, the experimentally detected dynamic displacement current, and the voltage across the gap. The dynamics of the streamer shape at the discharge stage was recorded with sub-nanosecond resolution using a four-channel ICCD camera, simultaneously with the electric characteristics of the discharge. The time dependences of the radius, position, and propagation velocity of the streamer front in both axial and radial directions at the initial breakdown stage are obtained.
期刊介绍：
Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
