Abstract

The Laser Megajoule facility, developed by the CEA is based on 176 Nd:glass laser beams focused on a micro-target positioned inside a 10-meter diameter spherical chamber. The facility will deliver a total energy of 1.4MJ of UV light at 0.35 μm and a maximum power of 400 TW. A specific petawatt beam, PETAL, offers a combination of a very high intensity beam, synchronized with the nanosecond beams of the LMJ. This combination allows expanding the LMJ experimental field in the High Energy Density Physics (HEDP) domain. Since September 2021, a major project milestone has been achieved with the commissioning of the half LMJ (88 beams are fully operational with 10 heating bundles of 8 beams and a specific bundle for plasma diagnostics purpose). The installation and the commissioning of new laser bundles and new plasma diagnostics around the target chamber are continuing, simultaneously to the realization of plasma experiments. Another project milestone has been achieved at the end of 2021, with a dedicated laser experiment in the facility to explore the Power-Energy Diagram.
