DIII-D – Old Reactor with a New Trick?

Researchers flipped the orientation of the plasma chamber on the DIII-D tokamak designed reactor. By just flipping the orientation on this 1980s reactor the researchers found that the pressure inside increased enough to meet the requirements for fusion reactions to take place. Another bonus, the plasma was more stable. Unfortunately due to it’s design the reactor is not built to support necessary temperature or pressure for actual reactions to take place. These results may lead to a new build or another organization taking these latest results and producing a reactor that could produce fusion.

The takeaway is that any fusion research could be one “did you try it in reverse” step away from producing a better reaction.
