## Abstract Numerical simulation of turbulent MHD dynamics of beryllium seeded plasmas at the edge of tokamaks is performed. The model is based on the 4βfluid {__β οΈ, n, p~e~, p~i~__ } reduced nonlinear Braginsky's MHD equations. Neutral hydrogen flow from the wall is described with a diffusion mode
A poloidally oriented electrical probe array immersed into the plasma edge providing spatially and temporally resolved information of the plasma density and potential is used to study plasma edge turbulence a t the CASTOR tokamak ( R = 0.4 m, a = 0.085m). A model of 'eddies' formulated in [l] is exp
