Abstract
Data on plasma disruption processes in the modernized Globus-M2 spherical tokamak are presented.
Electron temperature and density profiles before the disruption, immediately after thermal quench
and in the stage of plasma current quench are measured using the diagnostics of Thomson scattering of laser
radiation. The dependence of the plasma current decay time during disruption on the pre-disruption current
value is determined. The distribution of the toroidal current, which is induced during disruption, in the shell
of the vessel is determined on the basis of magnetic measurements. Electromagnetic loads on the vessel are
calculated.
