Princeton Plasma Physics Laboratory (PPPL) scientists have discovered a remarkably simple way to suppress a common instability that can halt Tokamak fusion reactions and damage the walls of reactors built to create a “star in a jar.” The findings, published in June in the journal Physical Review Letters, stem from experiments performed on the National […]

Recent computer simulations have suggested a novel method for launching the plasma without using solenoids. The simulations at the National Spherical Torus Experiment (NSTX), the major fusion facility at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) shows the formation of distinct, current carrying magnetic structures called plasmoids that can initiate the plasma […]

General Atomics (GA) researchers working at the firm’s DIII-D National Fusion Facility have created an important new tool for controlling fusion plasmas that are hotter than the sun in collaboration with scientists from the University of California-Irvine and Princeton Plasma Physics Laboratory. This is the second post of three that started yesterday. Energy and momentum […]

The American Physical Society had a major news day last Friday with noteworthy and informative presentation announcements for their annual meeting in San Jose, California. The four announcements deal with progress on measuring controlling and building plasma devices. These topics are critical to progress because plasma is very hot, usually under pressure and in high […]

A collaboration of researchers at the University of Gothenburg and the University of Iceland has been studying a new type of nuclear fusion process. The new process idea produces almost no neutrons but instead fast, heavy electrons (muons), since it is based on nuclear reactions in ultra-dense heavy hydrogen (deuterium). The Gothenburg press release offers […]
