Pulsed discharge plasma and its application is one of the promising directions in civilian
areasof pulsed power technology. In order to promote the research and development ofthe …

We investigate how photoionization, electron avalanches and space charge affect the
inception of nanosecond pulsed discharges. Simulations are performed with a 3D PIC-MCC …

We derive that lightning can start if the electric field is 15% of the breakdown field, and if
elongated ice particles of 6 cm length and 100 free electrons per cm 3 are present. This is …

In particle simulations, the weights of particles determine how many physical particles they
represent. Adaptively adjusting these weights can greatly improve the efficiency of the …

The complex dynamics of a sprite discharge are not limited to the propagation of streamers.
After the passage of a streamer head, the ionized channel established in its wake develops …

Positron beams have been observed by the Fermi satellite to be correlated with lightning
leaders, and neutron emissions have been attributed to lightning and to laboratory sparks as …

The purpose of this paper is to introduce electrical discharge phenomena known as
transient luminous events above thunderstorms to the lightning protection community …

Residual charged particles from previous discharges or external sources can produce some
localized plasma regions, so called plasma patches in a discharge gap. Such plasma …

One of the main problems in the Ultra High Voltage (UHV) transmission project is to choose
the external insulation distance, which requires a deep understanding of the long air gap …

We investigate discharge inception in air, in uniform background electric fields above and
below the breakdown threshold. We perform 3D particle simulations that include a natural …
