ITER Mag 2

Hotter than the sun

In the depths of the Sun where fusion reactions produce the energy that we perceive as light and heat, temperatures reach 15 million °C. In the centre of the ITER plasma temperatures will soar to between 150 and 300 million °C. How is such an environment possible? And what type of container will be host to an environment that is ten to twenty times hotter than the centre of the Sun?
