WebJan 13, 2024 · 1 Introduction. Plasma-wall interaction (PWI) is one of the most critical issues with respect to the performance, safety and availability of future fusion reactors, like ITER and DEMO [1–3].In these tokamaks, PWI conditions will be defined by high particle and heat fluxes to the plasma-facing components (PFCs). WebApr 13, 2024 · Important elements for ITER were developed there. Plasma operating conditions and components for later power plants are already being tested. A central element of ASDEX Upgrade and all modern magnetic fusion facilities is the divertor. This is a part of the vessel wall that is particularly heat-resistant and requires an elaborate design. WebThe ability to exhaust the plasma power loss from a large tokamak onto material walls surrounding the plasma has been perceived to be a large obstacle to the successful production of a fusion power reactor in the past. There have been tremendous strides in understanding the physics relevant to this power exhaust over the past five years. This … checker cab providence
