A three temperature model is constructed to describe dynamics of plasma parameters during argon injection, which is aimed to mitigate disruption consequences. Model predicts fast decrease of electron and ion temperatures, distribution of ionization stages and average ion charge in time, the rate of total radiation losses and time dependent intensities of ArXVII lines, widely used in plasma diagnostics. It was found that rapid drop of electron temperature is not associated with radiation losses (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
