Fundamental properties of plasmas in interaction with targets

ORAL

Abstract

The interaction of non-thermal atmospheric pressure plasmas and targets affects the properties of the gas-phase plasma. This presentation discusses the profile of the electric field in the gas phase and how it is affected by targets, the electron density profile and behaviour and the evolution of the discharge over time and it shows that the electrical properties of the target govern the behaviour of the discharge in the gas phase.
