	Comparative simulations of magnet configurations have been performed searching for the optimum design of bending magnets for the intense pulsed electron beam facility GESA-1M. GESA-1M is used for improvement of material surface properties and is capable to generate a 120 kV, 10 A/cm², 50 mks electron beam with the diameter of 10 cm. One of specific concerns is to prevent the beam path from contamination withμparticles of treated materials. To overcome this problem a system of bending magnets is used. The beam trajectory through electric and magnetic fields was simulated for three candidate configurations of the bending magnets. A comparison was focused on the expected power density and divergence angle at the target. The most efficient concept was found to be two pairs of coils arranged orthogonally to each other. This configuration produces highly uniform distribution of the current density at the target, the divergence angle being as low as several degrees. An important advantage is that the initial beam power can be intensified by a 20% at the target.
