ABSTRACT: High-energy high-intensity lasers are an emerging tool in physics which allow novel studies in particle acceleration, warm dense matter, nuclear physics with lasers, as important examples.
Europe is leading in this field of science with new laser systems just completed or under construction, i.e. PETAL and Apollon in France, ELI in Hungary, Romania, the Czech Republic, VEGA in Spain.
When such laser pulse are focused on targets, very intense electromagnetic pulses (EMPs) are generated with fields that, in the case of a later system like PETAL, are expected to reach 1 MV/m in vicinity of the target. It is clear that such huge electric fields pose a very serious issue with respect to the correct operation, and even the survival, of diagnostics based on electronics.
This issue is urgently demanding resolution; many of the cited laser systems are expected to begin operation very shortly. Collection and comparison of experimental data, obtained in several laser facilities, is needed. We also need to develop theoretical models, and numerical simulation tools, which can be validated and verifiied against existing data, and subsequently extrapolating to higher energies. Finally, we must develop tools to mitigate either the impact or the generation of EMPs.
For these reasons, we host a one-day workshop in Bordeaux, with the participation of scientists from various European laboratories (CELIA, CESTA, Rutherford Appleton Laboratory, Orion, CLPU Salamanca).
