DESCRIPTION:Disruption is a major threat to the operation of reactor-grade 
 tokamak devices. To avoid the localization of heat load and excessive elec
 tromagnetic force\, the disruption mitigation system such as MGI and SPI h
 as been developed. During disruption mitigation\, massive impurities cool 
 the plasma edge\, causing disturbances in the current density profile and 
 leading to global magnetohydrodynamic (MHD) instabilities. In this study\,
  the electrothermal dynamics of the electron temperature and current densi
 ty profiles were investigated using the 1.5D disruption simulator INDEX. W
 hen one recasts the current diffusion equation into the reaction-diffusion
  form\, the fact that the current density perturbation is driven by the re
 sistivity gradient and curvature is emphasized. The ongoing application of
  the INDEX code to ASDEX-SPI experiments will also be discussed.\nVortrage
