A simple model of the penetration of particle effluxes from the core plasma into the SOL‐plasma of tokamaks is proposed. The assumptions made are free streaming of particles parallel to the magnetic field and anomalous particle transport perpendicular to the toroidal field with a constant radial velocity. The model has been proved for measured particle fluxes of Li which was injected into the core plasma of the tokamak T‐10. The dependence of the Li‐particle flux on the minor radius as well as toroidal asymmetries in the SOL‐plasma can be explained by the results of the calculations.
