The D-shaped plasmas in Super H-mode experiments on DIII-D are able to reach ion temperatures of more than 30 million degrees in the pedestal region (the yellow areas of the cross sections), enabling the core plasma (orange areas) to reach optimal fusion temperatures of over 150 million degrees. During the experiments, the DIII-D plasma is the hottest spot in the solar system, far hotter than the core of the sun. [Image courtesy of General Atomics & Bill Meyer]
