Machine learning framework predicts micro-displacements of DIII-D fusion device coils

Researchers at the U.S. Department of Energy's (DOE) Thomas Jefferson National Accelerator Facility (Jefferson Lab) and collaborating teams have developed a machine learning framework that can predict subtle changes in critical fusion device hardware before the next experiment begins. The method targets the DIII-D National Fusion Facility in San Diego, and the findings have been published in the journal Machine Learning with Applications.

Hong Kong deputies to the National People's Congress visit Hefei to inspect fusion device and innovation industry development

On August 4, a delegation of Hong Kong deputies to the National People's Congress conducted an inspection and research visit in Hefei, Anhui Province. The itinerary included visits to the Hefei Innovation Museum, the Memorial Hall of the Crossing-the-Yangtze Campaign, and the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, to learn about the local layout of scientific and technological innovation, the construction of major scientific facilities, and the development of the nuclear fusion industry. At the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, the delegation visited the Experimental Advanced Superconducting Tokamak (EAST) nuclear fusion device. Often referred to as the "artificial sun," this device serves as an important scientific research platform for Hefei in advancing the cluster development of major scientific facilities and the growth of the nuclear fusion-related industry. The delegation also received briefings on the construction of the Hefei Future Science City and the layout of related industries. Hong Kong deputies to the National People's Congress...

U.S. Team Proposes New In-Situ Cleaning Method for Porous Tungsten Walls in Fusion Devices

Researchers from the U.S. Department of Energy's Princeton Plasma Physics Laboratory, Princeton University, and Pennsylvania State University have proposed an in-situ cleaning method for fusion system wall materials, which uses heating combined with neon plasma to remove contaminants from the surface of porous tungsten materials after components are installed and sealed within a vacuum chamber. The research findings have been published in *Nuclear Materials and Energy*. Image credit: Kyle Palmer / PPPL Communications Department. Fusion system walls must withstand extreme temperatures. Liquid lithium is considered a promising wall protection material, which can be retained within porous tungsten wall tile structures much like water absorbed by a sponge. However, this...
