FIELD: physics.
SUBSTANCE: method is carried out by using gradient dipole fields that have a gradient force impulse. By increasing the magnetic field of the gradient dipole, the beam is deflected to the output system and defocused to increase its radial size in the aperture region of the output device. When the magnetic field is increased, a part of the beam particles that enters the aperture of the output deflector is withdrawn from the accelerator, and the remaining part is focused and reintroduced into the equilibrium orbit. The magnitude of the magnetic field increases until all the particles of the beam are removed from the accelerator.
EFFECT: reducing the magnetic field distortions around the screen and decreasing the loss of beam particles in the deflector wall.
