Self-excitation of ballooning tearing modes; nature of the anomaly in the toroidal magnetic confinement of plasmas
Zakharov L. E., Riedel K.
A self-excitation of tearing modes associated with the plasma pressure has been found. This self-excitation leads to an unconditional instability of these modes in toroidal systems with a strong longitudinal field. The results thus reveal a general mechanism, which the present authors regard as the primary mechanism, for the configurational disruption which determines the loss of energy from tokamak and stellarator plasmas.
