Evolution equation of intermittency of low frequency vortices near wall in nuclear fusion devices

It is shown, that at development of instability due to a radial gradient of density in the crossed electric and magnetic fields in nuclear fusion installations the intermittency can be developed. It provides pulse anomalous particle transport. The ordered structure of low-frequency vortices is alternated with stochastic vertical turbulence. The spatial structure of these vortices have been constructed. The convective-diffusion equation of intermittency for radial dynamics of the electrons has been derived. The anomalous particle transport is depended on ratio of time of convective particle dynamics to period of intermittency. (author)
