ICF hohlraum experiments on the LMJ facility
ORAL
Abstract
We propose here to present a summary of our ICF hohlraum experiments on the LMJ laser facility, from the first one with neutron production to our next milestone, in a few years. The LMJ laser is now capable of producing up to 270 kJ of UV energy on target in 80 beams (20 quads) arranged in four cones, consisting of 5 quads in each cone. We first show how the beam arrangement naturally leads to a rugby shaped hohlraum. Then, we briefly present the first neutron production in a vacuum rugby hohlraum followed by the first gas fill hohraum shots. Finally, we present our future designs for the next years, as more energy and beams will be available. We show how trade-offs must be made between the irradiation symmetry on the capsule and the deleterious effects of laser plasma interaction which could become a main concern with the laser energy increase.
