摘要: A theoretical model of L-H transition in a tokamak, based on the self-consistent analysis plasma transport and taking suppression anomalous by sheared poloidal rotation establishment radial electric field due to non-ambipolar particle into account, is presented. The an improved confinement regime for with or without suprathermal electron component studied. numerical simulation shows that this adequately describes main, experimentally observed features dynamics during cyclotron lower hybrid heating. It also shown certain conditions such can be 'auto-oscillatory', which may considered as ELMs feature. dependence localization region their characteristics (frequency magnitude) parameters are investigated
