CEA Cesta

CEA/Cesta or simply Cesta (French: Centre d'études scientifiques et techniques d'Aquitaine; English: Center for scientific and technical study of Aquitaine) is a French research facility (CEA, Direction of Military Applications) dedicated to the design of nuclear weapons.

The center was established in 1965 on the commune of Le Barp between Bordeaux and Arcachon.

The center will host in the future the Megajoule laser (LMJ), which will enable French nuclear scientists to validate models of nuclear explosion without having to conduct nuclear testing. The LMJ is the French equivalent of the National Ignition Facility.
