Abstract:
The torque applied to the plasma during the high-energy neutral beam co-injection in the TUMAN-3M tokamak was carried out. The dependence of the torque in the central and peripheral regions of the plasma column on the high-energy neutral beam power, plasma concentration, the beam and plasma isotopic composition, and other parameters was studied. The calculation shows the existence of an optimal value of plasma concentration at which the magnitude of the torque to the plasma reaches its greatest value. In the case of hydrogen beam injection into a hydrogen plasma, the magnitude of the moment in the central region of the plasma has a maximum value compared to other variants of the isotopic composition. An estimate is made of the radial electric field generated at the periphery of the plasma.
