A study on the behavior of runaway electrons beam position in Damavand tokamak has been performed using the current filament model (CFM). The experimental data used in these calculations are based on the measurements obtained from Damavand Tokamak magnetic probes and in all experiments runaway discharges have been used in which most or all of the plasma current is carried by runaway electrons. In the CFM method, the current of the runaway electrons is approximated by a finite number of current filaments, and using the relevant calculations along with the classical method of least squares, the displacement of the runaway electrons beam in the radial and vertical directions in Damavand tokamak is investigated. The most important result obtained from these calculations (in runaway discharges) indicates the displacement of the runaway electrons column in the radial direction and their collision with the external limiter during the most time of plasma presence.
