ßp-collapse induced VDE and its underlying mechanism in the TCV Tokamak
The interaction between a disruptive tokamak plasma and a surrounding resistive shell plays an important role in the dynamics of a Vertical Displacement Event (VDE). Describes onset mechanisms of VDEs induced by a strong plasma pressure drop (ßp-collapse) in disruptive discharges of the Tokamak Configuration Variable (TCV). Many aspects of the TCV vertical instability have been investigated. Computes the open-loop growth rates of VDEs in TCV using Tokamak Simulation Code (TSC) and compares the results with JT-6OU. Investigates the eddy current effects due to a ßp-collapse for disruptive and non-disruptive TCV discharges in nonlinear TSC simulations.
