Nuclear Fusion
PPPL physicist conducts experiments indicating efficiency of fusion start-up technique
Physicist Fatima Ebrahimi at the US Department of Energy's Princeton Plasma Physics Laboratory and Princeton University has for the first time performed computer simulations indicating the efficiency of a start-up technique for doughnut-shaped fusion machines known as tokamaks. The simulations show that the technique, known as coaxial helicity injection, could also benefit tokamaks that use superconducting magnets.

Physics of Plasmas
PPPL researchers advance understanding of turbulence that drains heat from fusion reactors
Physicists at the US Department of Energy's Princeton Plasma Physics Laboratory appear to have gained important new insights into what affects plasma turbulence, which can impact the leakage of heat from the fusion plasma within tokamaks. Understanding how fusion plasmas lose heat is crucial because the more a plasma is able to retain its heat the more efficient a fusion reactor can be.

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.
