The Max Planck Institute for Plasma Physics (IPP) was founded in Garching, Germany, in 1960, the same year that its Wendelstein 1a stellarator began operation. Wendelstein 7-X is now operating at IPP’s site in Greifswald, Germany, and one of the objectives the device was designed to achieve has recently been confirmed, IPP announced on August 12. Analysis by IPP scientists shows that the twisted magnetic coils of the device successfully control plasma energy losses, indicating that stellarator fusion devices could be suitable for power plants, according to a detailed analysis of experimental results published on August 11 in Nature.

U.S. scientists are getting funding to carry out seven research projects at two major stellarator fusion energy facilities located in Germany and Japan, the Department of Energy announced on June 8. A total of $6.4 million has been allocated for seven research projects with terms of up to three years.

U.K. and Chinese national fusion programs can take the heat

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.

ITER magnet assembly begins

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.
