The X-Point radiating regime at ASDEX Upgrade and TCV

Holger Reimerdes, Marco Wischmeier, Christian Gabriel Theiler, Umar Sheikh, Artur Perek, Bernhard Sieglin

Future fusion reactors require a safe, steady-state divertor operation. With deep divertor detachment, which is typically induced by impurity seeding, the radiation concentrates in a small region at the X-point or on closed flux surfaces above the X-point. ...
