Scientists propose solution to long-puzzling fusion problem

Posted by in category: computing

The paradox startled scientists at the U.S Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) more than a dozen years ago. The more heat they beamed into a spherical tokamak, a magnetic facility designed to reproduce the fusion energy that powers the sun and stars, the less the central temperature increased.

Big mystery

“Normally, the more beam power you put in, the higher the temperature gets,” said Stephen Jardin, head of the theory and computational science group that performed the calculations, and lead author of a proposed explanation published in Physical Review Letters. “So this was a big mystery: Why does this happen?”
