PPPL team wins 80 million processor hours on nation's fastest supercomputer
The US Department of Energy has awarded a total of 80 million processor hours on the fastest supercomputer in the nation to an astrophysical project based at the DOE's Princeton Plasma Physics Laboratory. The grants will enable researchers led by Amitava Bhattacharjee, head of the Theory Department at PPPL, and physicist Will Fox to study the dynamics of magnetic fields in the high-energy density plasmas that lasers create.

PPPL physicists use computers to uncover mechanism that stabilizes plasma within tokamaks
A team of physicists led by Stephen Jardin of the US Department of Energy's Princeton Plasma Physics Laboratory has discovered a mechanism that prevents the electrical current flowing through fusion plasma from repeatedly peaking and crashing. This behavior is known as a 'sawtooth cycle' and can cause instabilities within the plasma's core. The results have been published online in Physical Review Letters. The research was supported by the DOE Office of Science.

Scientists propose an explanation for puzzling electron heat loss in fusion plasmas
Scientist Elena Belova of the US Department of Energy's Princeton Plasma Physics Laboratory and a team of collaborators have proposed an explanation for why the hot plasma within fusion facilities called tokamaks sometimes fails to reach the required temperature, even as researchers pump beams of fast-moving neutral atoms into the plasma in an effort to make it hotter.
