PPPL researchers combine quantum mechanics and Einstein’s theory of special relativity to clear up puzzles in plasma physics (Phys. Rev. A)

By John Greenwald, Princeton Plasma Physics Laboratory Communications Among the intriguing issues in plasma physics are those surrounding X-ray pulsars — collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the sky.  Physicists want to know the strength of the magnetic field and density of the plasma … Continue reading PPPL researchers combine quantum mechanics and Einstein’s theory of special relativity to clear up puzzles in plasma physics (Phys.

PPPL physicists simulate innovative method for starting up tokamaks without using a solenoid (Nuclear Fusion)

By Raphael Rosen, PPPL Office of Communications Scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have produced self-consistent computer simulations that capture the evolution of an electric current inside fusion plasma without using a central electromagnet, or solenoid. The computer simulations of the process, known as non-inductive current ramp-up, were performed … Continue reading PPPL physicists simulate innovative method for starting up tokamaks without using a solenoid (Nuclear Fusion)

Identifying new sources of turbulence in spherical tokamaks (Physics of Plasmas)

By John Greenwald, Princeton Plasma Physics Laboratory Communications For fusion reactions to take place efficiently, the atomic nuclei that fuse together in plasma must be kept sufficiently hot. But turbulence in the plasma that flows in facilities called tokamaks can cause heat to leak from the core of the plasma to its outer edge, causing … Continue reading Identifying new sources of turbulence in spherical tokamaks (Physics of Plasmas)

An improvement to the global software standard for analyzing fusion plasmas (Nuclear Fusion)

By Raphael Rosen, Princeton Plasma Physics Laboratory The gold standard for analyzing the behavior of fusion plasmas may have just gotten better. Mario Podestà, a staff physicist at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), has updated the worldwide computer program known as TRANSP to better simulate the interaction between energetic particles … Continue reading An improvement to the global software standard for analyzing fusion plasmas (Nuclear Fusion)
