Simultaneous measurements of the mass collection rates by plates and hoppers have been realized along a pilot ESP in an industrial environment, together with on-line current, voltage, opacity measurements; they have been associated with on-site measu

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

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

Time-resolved visible spectroscopy of plasmas produced by laser breakdown of air using femtosecond Nd laser pulses (50–300 mJ, 500 fs) reveals features not observed with nanosecond laser pulses. Emission is initially dominated by molecular lines, s

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

The triggering and guiding of leader discharges using a plasma channel created by a sub-joule ultrashort laser pulse have been studied in a megavolt large-scale electrode configuration (3–7 m rod-plane air gap). By focusing the laser close to the p

In-flight experiments have shown that in most cases the aircraft striking process is initiated by the bidirectional propagation of two leaders of opposite polarities. A laboratory experiment has been designed to analyse in detail the development of s

A specific experiment has been designed to study the simultaneous development of two leaders of opposite polarities from a floating electrode suspended in a plane-to-plane gap. In the paper, the physical properties of both discharges are investigated
