In the decade since Lawrence Livermore National Laboratory’s National Ignition Facility began operations, NIF has routinely heated and compressed matter to some of the most extreme temperatures and pressures ever obtained on Earth – temperatures of 100 million degrees and pressures 100 billion times that of the Earth’s atmosphere. More than 2,700 experiments have helped to ensure the current and future nuclear stockpile is safe, secure and effective; made significant progress toward fusion ignition; and yielded new insights about the stars and the universe while revealing phenomena like the metallization of hydrogen and the interiors of distant planets.
The Department of Energy (DOE), National Nuclear Security Administration (NNSA) and Lawrence Livermore National Laboratory (LLNL) today announced the signing of contracts with Cray Inc. to build the NNSA’s first exascale supercomputer, “El Capitan.” When delivered in late 2022, El Capitan will have a peak performance of more than 1.5 exaflops (1.5 quintillion calculations per second), about 10 times faster than LLNL’s current most powerful supercomputer, Sierra. The total contract award is valued at $600 million.
Gold is an extremely important material for high-pressure experiments and is considered the ‘gold standard’ for calculating pressure in static diamond anvil cell experiments. When compressed slowly at room temperature (on the order of seconds to minutes), gold prefers to be the face-centered cubic (fcc) structure at pressures up to three times the center of the Earth. However, researchers from Lawrence Livermore National Laboratory and the Carnegie Institution of Washington have found that when gold is compressed rapidly over nanoseconds (1 billionth of a second), the increase in pressure and temperature changes the crystalline structure to a new phase of gold. This well-known body centered cubic (bcc) structure morphs to a more open crystal structure than the fcc structure.
