The Megajoule Laser – A High-Energy-Density Physics Facility
The French Commissariat à l’Energie Atomique (CEA) is currently building the Laser Megajoule (LMJ), a 240-beam laser facility, at the CEA Laboratory CESTA near Bordeaux. The LMJ will be a cornerstone of the CEA’s “Programme Simulation,” the French Stockpile Stewardship Program. It is designed to deliver 1.8 MJ of 0.35 μm light to targets for high-energy-density physics experiments, among which fusion experiments. LMJ technological choices were validated with the Ligne d’Intégration Laser (LIL), a scale 1 prototype of one LMJ bundle built at CEA/CESTA. It delivered 9.5 kJ of UV light (0.35 μm) in less than 9 ns from a single laser beam in May 2003. This chapter will present results from the commissioning phase of the LIL program in 2003 and 2004. The construction of the LMJ facility itself started in March 2003. The LMJ will be commissioned early 2011, and the first fusion experiments begin late 2012.
