### Abstract

A 3D model to describe the spreading of non-intrinsic impurity ions in magnetized plasma is presented. The model is based on the kinetic theory and takes into account the Coulomb collision with background plasma in a linearized form, electron impact ionization, drift and diffusion across the magnetic field lines. The predictions of the model are calculated using Monte Carlo simulation. The results of the simulation are compared with experimental results obtained on the MT-1M tokamak using lithium injection, and the agreement is found to be satisfactory. Some more numerical calculations are presented to describe the effect of plasma rotation on the spreading of the injected impurities.
