Controlling ITER with fuelers, ticklers and terminators

摘要

When it's up and running, the ITER fusion experimental reactor will be very big and very hot, with more than 800 cubic meters of hydrogen plasma reaching 170 million degrees Celsius. The systems that fuel and control it, on the other hand, will be small and very cold. ORNL researchers are developing three systems that shoots pellets of frozen gas into ITER's plasma to keep it fueled and under control. Larry Baylor of ORNL's Plasma Technology and Applications Group calls the systems "fuelers," "ticklers" and "terminators."
