dc.description.abstract | 3D non-linear MHD simulations of a D2 massive gas injection (MGI) triggered disruption in
JET with the JOREK code provide results which are qualitatively consistent with experimental
observations and shed light on the physics at play. In particular, it is observed that the gas
destabilizes a large m/n = 2/1 tearing mode, with the island O-point coinciding with the gas
deposition region, by enhancing the plasma resistivity via cooling. When the 2/1 island gets
so large that its inner side reaches the q = 3/2 surface, a 3/2 tearing mode grows. Simulations
suggest that this is due to a steepening of the current profile right inside q = 3/2. Magnetic
field stochastization over a large fraction of the minor radius as well as the growth of higher
n modes ensue rapidly, leading to the thermal quench (TQ). The role of the 1/1 internal kink
mode is discussed. An Ip spike at the TQ is obtained in the simulations but with a smaller
amplitude than in the experiment. Possible reasons are discussed. | es |
