“…In J-TEXT, the vacuum vessel has two isolated parts. The distribution of eddy currents induced in the vessel wall has been analyzed in [32], the loss of magnetic energy via eddy currents can be estimated utilizing a Maxwell simulation and this is also negligible compared with magnetic energy dissipated in the VV [2]. Therefore, the magnetic energy loss in VV mainly contributes to the increase of kinetic energy carried by REs during RE plateau.…”

A large number of runaway electrons (REs) with energies as high as several tens of megaelectron volt (MeV) may be generated during disruptions on a large-scale tokamak. The kinetic energy carried by REs is eventually deposited on the plasma-facing components, causing damage and posing a threat on the operation of the tokamak. The remaining magnetic energy following a thermal quench is significant on a large-scale tokamak. The conversion of magnetic energy to runaway kinetic energy will increase the threat of runaway electrons on the first wall. The magnetic energy dissipated inside the vacuum vessel (VV) equals the decrease of initial magnetic energy inside the VV plus the magnetic energy flowing into the VV during a disruption. Based on the estimated magnetic energy, the evolution of magnetic-kinetic energy conversion are analyzed through three periods in disruptions with a runaway current plateau.
