Description

Tokamak disruptions have the potential to create runaway electrons (RE) and if unmitigated, could cause severe localized damage. The physics of RE are not sufficiently understood and TCV has developed an extensive set of controls and diagnostics to contribute to this field of research. Successful mitigation of RE beams on TCV has been achieved through three techniques: 1) controlled ramp-down of the RE current to a few kA; 2) mitigation through high-Z gas injection; and 3) plasma restart within the confining poloidal field generated by the RE beam.
