As governments around the world cooperate on the ITER tokamak and, in parallel, race each other and private companies to develop commercial fusion power concepts, it seems that “game-changing” developments are proclaimed almost weekly. Recently, the United Kingdom and China announced new fusion program results.

On April 26, as the ITER Organization announced that magnet assembly had begun with the April 21 placement of the divertor coil in the bottom of the machine, the organization also published an Image of the Week that bears an unmistakable—and unintentional—resemblance to the Olympic rings. The pre-compression rings were being prepped for installation in the ITER Assembly Hall when the serendipitous arrangement was captured by Bruno Levesy, a project manager at ITER.
