Major next steps proposed for fusion energy based on the spherical tokamak design (Nuclear Fusion)

By John Greenwald, Princeton Plasma Physics Laboratory Among the top puzzles in the development of fusion energy is the best shape for the magnetic facility — or “bottle” — that will provide the next steps in the development of fusion reactors. Leading candidates include spherical tokamaks, compact machines that are shaped like cored apples, compared … Continue reading Major next steps proposed for fusion energy based on the spherical tokamak design (Nuclear Fusion)

PPPL scientists challenge conventional understanding and improve predictions of the bootstrap current at the edge of fusion plasmas (Physics of Plasmas)

By John Greenwald, PPPL Office of Communications Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have challenged understanding of a key element in fusion plasmas. At issue has been an accurate prediction of the size of the “bootstrap current” — a self-generating electric current — and an understanding of what … Continue reading PPPL scientists challenge conventional understanding and improve predictions of the bootstrap current at the edge of fusion plasmas (Physics of Plasmas)
