Sandia’s Z machine has produced plasmas that exceed temperatures of 2 billion degrees Kelvin — hotter than the interiors of stars. The unexpectedly hot output, if its cause were understood and harnessed, could eventually mean that smaller, less costly nuclear fusion plants would produce the same amount of energy as larger plants.
The phenomena also may explain how astrophysical entities like solar flares maintain their extreme temperatures.
“At first, we were disbelieving,” says Sandia project lead Chris Deeney. “We repeated the experiment many times to make sure we had a true result and not an ‘Ooops’!”
The results, recorded by spectrometers and confirmed by computer models created by John Apruzese and colleagues at Naval Research Laboratory, have held up over 14 months of additional tests.
Believe me. Everyone in New Mexico is happy when no one at Sandia says, “Oops!”
