CORRECTION OF TOROIDAL DISPLACEMENT OF DIAGNOSTIC HEAVY ION BEAM
( Pp. 58-61)

One of the main factors affecting the measurement of plasma potential in non-stationary regimes of tokamaks and stellarators is uncontrolled toroidal displacement of the probing beam under the influence of a poloidal magnetic field. The paper presents a device that allows us to automatically compensate the non-stationary toroidal displacement, thereby significantly expand the range of operating modes of Heavy Ion Beam Probing. Examples of measurement results obtained with the help of the developed device are given. A significant increase in the duration of reliable measurements of the plasma potential on the T-10 tokamak is shown.
