Description
Wendelstein 7-X (W7-X) is the largest and most advanced superconducting stellarator currently in operation. The primary objective is to demonstrate the ability to maintain a steady-state plasma with fusion-relevant plasma parameters and thus proving that the stellarator is a viable fusion power plant concept. In the most recent test campaign, the new and fully water-cooled divertor was tested with a heating power of up to 7 MW and a long-pulse operation of up to 8 minutes with 1.3 GJ of injected energy was achieved.
While electron temperatures of up to 5 keV and densities of 2.4×10
The presentation will give an overview of the development and application of some diagnostics in relation to the aforementioned requirements.
