Based on the state-of-the-art knowledge, the processes of formation and transport of intensive ion beams in the transverse magnetic field of a commercial electromagnetic separator are analyzed. For the first time, it is shown that suppressing the low-frequency noise oscillations in an arc discharge of an ion source allows for the formation of a highly stable ion beam with a minimum inner potential drop possible. At low pressures, the drop is determined by Coulomb's collisions between the beam particles and compensating electrons, the collisions being unremovable in principle.
