Researchers around the world are working on an efficient, reliable way to contain the plasma used in fusion reactors, potentially bringing down the cost of this promising but technically elusive energy source.
Researchers at the University of Washington, claim that a new device, dubbed the "Mug Handle," could help contain and stabilize the plasma. Their findings were presented at the recent 24th annual Fusion Energy Conference in San Diego.
The new equipment looks like handles on a coffee mug—except they attach to a vessel containing a million-degree plasma that is literally too hot to handle.

KSTAR aims for longer plasmas
At the Korea Institute of Fusion Energy (KFE), the KSTAR tokamak recommenced operations in December after a major upgrade to replace the device's carbon divertor with a tungsten divertor.
According to an article on the KFE website, the original carbon divertors could take a thermal load of 5MW/m², whereas the tungsten divertor can take 10MW/m². The upgrade is critical to the goal of sustaining a 100-million-degree plasma for 300 seconds by 2026. Data from the operational campaign will be directly relevant to ITER, which will operate a tungsten divertor under similar plasma conditions in terms of shape and structure.
This testing campaign will continue through February 2024. Read more about the plans in this article in English on the KFE website, or in Korean in the Chosun Biz.
