Description
With the advent of multi-PW lasers, it is foreseen that laser-driven proton beams could reach hundreds of MeV energy cutoff. In this regard, an application for such high energy protons could be the creation of ultra intense laser-driven neutron sources. Indeed through the spalliation process, it is possible to efficiently convert those high energy protons into neutrons with a widespread spectrum, up to the energy cutoff of the incoming proton beam.
In order to characterize such neutron sources, one must first develop detection devices adapted to the peculiar environment of the ultra high intensity lasers. In this regard, we present here some neutron detectors that has been tested during the commissioning of the E1 10 PW area and the first results obtained.
