The first experiments at Lawrence Livermore National Laboratory's National Ignition Facility (NIF) have demonstrated a unique physics effect that bodes well for NIF's success in generating a self-sustaining nuclear fusion reaction. In inertial confinement fusion experiments on NIF, the energy of 192 powerful laser beams is fired into a pencil-eraser-sized cylinder called a hohlraum, which contains a tiny spherical target filled with deuterium and tritium, two isotopes of hydrogen. Rocket-like compression of the fuel capsule forces the hydrogen nuclei to combine, or fuse, releasing many times more energy than the laser energy that was required to spark the reaction.[
