Current Sharing Between Plasma And Walls In Tokamak Disruptions

Authors: Leonid E. Zakharov, Sergei A. Galkin

Abstract:
Plasma disruptions in tokamaks represent a significant obstacle in enhancing performance of the plasma regime. In the next step machines, such as ITER, disruptions impose very challenging requirements on the design of the structural elements of the machine and its in-vessel components. Although, regarding the global forces due to disruptions on the vacuum vessel there is sufficient certainty because of explicit scalings, e.g., from JET to ITER, many important aspects of plasma interaction with the plasma facing components (localization of forces, their impulse, rotation, etc) require additional consideration.
