Operating principle of the 4-side irradiation system
The operating principle of the device is based on the deflection of an electron beam by a magnetic field. The scanning electromagnets scanned the extracted electron beam. Then the beam comes to the constant field of turn electromagnets (Fig. 1).

This field changes the trajectories of electrons so that, regardless of the place of entry, at the exit all electrons have an angle with the vertical axis of ±45°. Transporting the cable through the irradiation zone, its orientation changes by 180°, which is why four-sided irradiation occurs (Fig. 2.).
