National Ignition Facility 描述
The NIF App provides news, images and videos. Keep tabs on NIF's bright future.
The National Ignition Facility (NIF) is the world's largest and most energetic laser system. The NIF's 192 intense laser beams can deliver nearly two million joules of ultraviolet laser energy in billionth-of-a-second pulses, more than 60 times the energy of any previous laser system. When all that energy hits a millimeter-sized target, it can generate temperatures of more than 100 million degrees and pressures more than 100 billion times the Earth's atmosphere—conditions only found in stars and the cores of giant planets or in nuclear weapons.
The goal of NIF is to achieve fusion by compressing and heating a pea-sized capsule containing a mixture of deuterium and tritium. This process will cause the fusion fuel to ignite and burn, producing more energy than the initial laser energy. Achieving nuclear fusion in the laboratory is at the heart of the directorate's three complementary missions: ensuring the safety, security and effectiveness of the nuclear weapons stockpile without underground testing; blazing the path to a safe, virtually unlimited, carbon-free energy future; and achieving breakthroughs in a wide variety of scientific disciplines, including astrophysics, materials science, and plasma physics.
NIF is a program of the U.S. Department of Energy's National Security Administration (NNSA) and is run by the NIF & Photon Science Principal Directorate at Lawrence Livermore National Laboratory (LLNL) in Livermore, California.
