Giant structures called plasmoids could simplify the design of future tokamaks

Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have for the first time simulated the formation of structures called "plasmoids" during Coaxial Helicity Injection (CHI), a process that could simplify the design of fusion facilities known as tokamaks. The findings, reported in the journal Physical Review Letters, involve the formation of plasmoids in the hot, charged plasma gas that fuels fusion reactions.

An improvement to the global standard for modeling fusion plasmas

The gold standard for modeling 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 and instabilities – disturbances in plasma that can halt fusion reactions.

Engineer Russ Feder leads development of diagnostic tools for US ITER as physicist Dave Johnson shifts to part-time work

In a rare transition, engineer Russ Feder has stepped into a management job that a distinguished physicist last held. Feder leads PPPL’s development of all diagnostic tools for US ITER, which manages U.S. contributions to the international ITER experiment, succeeding physicist Dave Johnson in that role. “I’m excited to keep the momentum going and proud to be part of our strong team,” Feder said.  “I also recognize the tough challenges of the job and will need the help of our team and the U.S. diagnostics community to be successful.”
