Self-excitation of the ballooning tearing mode and the nature of anomalous transport in toroidal magnetic confinement systems
Abstract
The self-excitation of the ballooning tearing mode in toroidal systems with strong magnetic fields is discovered. This instability is driven by the pressure gradient at small islands and arises from the coupling of poloidal harmonics. This instability is always unstable with respect to perturbations of finite size. In our opinion, it is the main mechanism for plasma turbulence and therefore defines the energy confinement time in tokamaks and stellarators.
