On the plasma confinement in the m=1, n=1 kink distorted tokamak central coreFunded under: FP2-FUSION 10C
It is shown that kink distortion of the magnetic axis, and as a consequence a variation of the magnetic field along magnetic surfaces in the toroidal direction, leads to a new type of superbanana particle orbit and can drastically change the particle and heat transport in the central core. The phenomena discussed have a time scale of approximately 1.0 E-3 s and seem to be too slow to affect the sawtooth crash process (which is an order of magnitude faster) but can dominate in evolution of the plasma parameters between crashes, snakes formation and other phenomena in the central plasma inside the q = 1 magnetic surface.
