Demonstration of reduced neoclassical energy transport in Wendelstein 7-X

C. D. Beidler, Håkan M. Smith, Arturo Alonso, Tamara L Andreeva et autres

Abstract Research on magnetic confinement of high-temperature plasmas has the ultimate goal of harnessing nuclear fusion for the production of electricity. Although the tokamak1 is the leading toroidal magnetic-confinement concept, it is not without shortcomings and the fusion community has therefore also …

Understanding baffle overloads observed in high-mirror configuration on Wendelstein 7-X

Yu Gao, M. Jakubowski, J. Geiger, M. Endler et autres

The operational regimes in the first divertor campaign of W7-X were limited by unexpectedly high heat loads on certain baffle tiles. In the high-mirror configuration, a permanent hotspot on the baffle plate was detected by the thermographic system, which was further confirmed …
