A matter of size



The JT-60SA tokamak, a joint R&D project involving Japan and Europe, is in no way a small machine. Standing 15,5 metres high, with a plasma volume of 130 cubic metres, it will dethrone JET as the largest operating tokamak in the world.

But compare the size of one of JT-60SA's D-shaped toroidal field coils on the left, to one of ITER's on the right, and you'll have an idea of just how large the ITER machine will be.
