Feedback control of tearing modes via modulated neutral beams
- Institute for Plasma Research, Bhat 382 424 (India)
Tearing modes are suspected to be a principal cause of both minor and major disruptions in a tokamak. Suppression of these modes via a neutral beam which supplies momentum, energy and particles of appropriate phase and amplitude is considered. Model theoretical calculations are presented for the stabilization of drift tearing modes and it is found that for ADITYA [S.B. Bhatt {ital et al.}, Ind. J. Pure Appl. Phys. {bold 27}, 710 (1989)] and other present-day tokamak parameters, stabilization is achievable using modest levels of beam power, current and density. {copyright} {ital 1997 American Institute of Physics.}
