Study of thermal quench of discharge using a massive gas injection into the plasma of T-10 tokamak

The report presents the results of simulations of plasma disruption in the T-10 tokamak using the ASTRA code, including discharges with a disruption being initiated by the massive gas injection (MGI). This study focuses on the development phase of thermal quench, and the effect of different channels...

Description
Summary:The report presents the results of simulations of plasma disruption in the T-10 tokamak using the ASTRA code, including discharges with a disruption being initiated by the massive gas injection (MGI). This study focuses on the development phase of thermal quench, and the effect of different channels of heat loss during quench evolution is examined. It is shown that the initial phase of the slow phase of thermal quench can be described by the selection of sources and transport coefficients.
