Abstract
In the TMI tokamak current spikes into elements of the poloidal limiter were observed during disruptions Currents flowed between limiter elements located at the outboard side and inboard side of the torus as well. Simultaneously, the variation of the plasma column vertical position is observed. The direction of this shift coincided with that of a force produced by currents between poloidal limiter elements and the toroidal magnetic field. The correlations between vertical shift, current flowing to limiters and the shift along the major radius were investigated in the small TF tokamak. During major disruptions in the TEXTOR tokamak the currents flowing between the ALT-II toroidal belt limiter and the liner were recorded.
