  The report represents a beam scanning system for irradiation of opposite sides of the boxes during one pass. This beam scanning system contains the well-known scanning system composed of scanning magnet and vacuum chamber with the beam extraction window covered by titanium foil. The bending magnet, which is located on the edge of this vacuum chamber, turns the electron beam to the metallic pipe, connected with the vacuum chamber. The metallic pipe goes sideways from the irradiated boxes and is connected with the second vacuum chamber, located inside of a 180 degrees bending magnet. Electrons are turning on 180 degrees and scanning along the opposite side of the boxes due to the hyperbolic shape of the current in a coil of the 180 degrees bending magnet. Therefore, electrons are scanning along one side of the box, then round the box sideway through the metallic pipe and scanning along the opposite side of this box after turning 180 degrees. The full cycle of the scanning can be repeated up to 6 times per second. The experimental results of this system operation with 10 MeV, 12 kW electron beam are given in this report.
