NOVA is a ten-beam, 50,000 joule laser used for ICF research. The target chamber, pictured above, is fabricated from aluminum, and supports the ten large final-optics assemblies which focus laser energy onto a variety of targets, including into hohlraums the size of grains of rice. Targets enter on a target-positioner arm from the top of the chamber, while a variety of instruments for observing target phenomena and capsule compression can be inserted through other small ports in the target chamber wall.
