When whistler waves are present in a fusion plasma, runaway electrons pay attention.
A research team led by the Department of Energy’s Oak Ridge National Laboratory is the first to directly observe the elusive waves inside a highly energized magnetic field as electrons zoom ar...
When it’s up and running, the ITER fusion reactor will be very big and very hot, with more than 800 cubic meters of hydrogen plasma reaching 170 million degrees centigrade. The systems that fuel and control it, on the other hand, will be small and very cold. Pellets of frozen gas will be shot int...
