Study on the transport of oxygen nuclei in the T-10 tokamak plasma by the corpuscular-spectroscopic method

Value of radial flux of oxygen nuclei in the T-10 tokomak plasma was determined by corpuscular-spectroscopic method with 40-50% accuracy. The flux was calculated on the basis of stationary equation of ionization balance for nuclei and hydrogen-like ions with the use of experimentally obtained radial distributions of their concentrations. The flux of oxygen nuclei differs sufficiently from neoclassical one and corresponds to impurity ion transport from plasma center to the periphery. The possible reason of anomaly can lie in transport of locked ions due to nonlinear interaction with the field of helical instability
