ITER-like vertical stabilization system tested on EAST tokamak
At the EAST tokamak in China, five Italian scientists recently joined their Chinese colleagues to participate in a week-long experiment aimed at testing a voltage-driven vertical stabilization system. The successful tests, carried out in the framework of a joint ASIPP-CREATE-ENEA collaboration, were a key step on the way to MIMO (multiple input, multiple output) control of advanced tokamak configurations, capable of decoupling shape control from vertical stabilization.
The new vertical stabilization system implemented and tested on EAST is identical to the one proposed for ITER, and these first tests show that it is compatible with the installation a new ITER-like multivariable shape controller for advanced configurations.

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.
