International audience; The paper [1] reports on comparative experiments on a triggered-gap electrode used as an early streamer emission air terminal, with some equivalent circuit analysis of the triggering circuit and simplified electric field calcu

A dynamic model for exposure of grounded objects to direct lightning strokes has been generalized to apply to buildings and massive structures. The model also applies to the mixed situation where a slender air terminal is installed on the top of a bu

This paper introduces a new mathematical model of positive leader propagation speed based on intense ionization in a thin boundary layer ahead of the tip of the leader channel. The model explicitly accounts for the effect of overvoltage and the resul

Using a plasma channel produced by an ultrashort laser pulse, we have studied the laser triggering and guiding of a positive leader from the tip of a 2-m vertical rod standing on the bottom plane of a 7-m plane-plane gap. The purpose of this setup wa

We have used the Bondio-Gallimberti model of positive leader propagation to simulate laboratory experiments of laser triggering and guiding of upward leaders initiated from a ground rod. The model proves to be capable of reproducing all the important

This paper summarizes the research this team has performed over the past few years investigating laboratory electrical breakdown discharges in the presence of a plasma cylinder created by a single ultrashort laser pulse. This work is part of a feasib

With the aim of elucidating the role of thermal effects in air in the leader propagation, the properties of the ionized air (charged species densities, electric field, and air temperature) in a limited region near the tip of the positive leader were
