摘要: This paper is an extension of the brief study by Sarah Douglas et al. [Phys. Plasmas 20 (2013) 114504] where in a sinusoidal perturbation heating power has been studied. In this stepwise increase and its influence on L–H transition are Using function, Atanh(t/T) for input tokamak plasmas, i.e. addition perturbation, Atanh(t/T), to constant q0 shown promote confinement, leading at lower value q0, as compared case without perturbation. It seen that Q consists part function provides relatively small A much wider range values 1/T 114504].
