Physical Review Letters 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.

Physical Review Letters PPPL physicists find clue to formation of magnetic fields around stars and galaxies
An enduring astronomical mystery is how stars and galaxies acquire their magnetic fields. Physicists Jonathan Squire and Amitava Bhattacharjee at the US Department of Energy's Princeton Plasma Physics Laboratory have found a clue to the answer in the collective behavior of small magnetic disturbances.

Physical Review Letters 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.

Physical Review Letters X marks the spot: Researchers confirm novel method for controlling plasma rotation
Timothy Stoltzfus-Dueck, a physicist at the US Department of Energy's Princeton Plasma Physics Laboratory, has demonstrated a novel method that scientists can use to manipulate the intrinsic - or self-generated - rotation of hot, charged plasma gas within fusion facilities called tokamaks.

Physical Review Letters Giant structures called plasmoids could simplify the design of future tokamaks
Researchers at the US Department of Energy's Princeton Plasma Physics Laboratory have for the first time simulated the formation of structures called 'plasmoids' during Coaxial Helicity Injection, a process that could simplify the design of fusion facilities known as tokamaks.
