<p>In a device for irradiation of objects with electrons an electron accelerator (1) is so located that its axis is parallel to the plane of the magnetic circuit frame of a deflecting electromagnet (6) which is placed in front of the outlet window (4) of a vacuum scanning chamber (3) for directing the electron beam on the irradiated object (5) at an angle close to the right one. A scanning electromagnet (7) has a bias winding (10) supplied with the direct current and intended for directing the electron beam to the aperture of the deflecting electromagnet (6) whereas a sweep current generator (9) is provided with a correction circuit (12) for decreasing the speed of the current change in the scanning winding (8) of the scanning electromagnet (7) as the electron beam moves to the most distant edge from the accelerator (1) of the deflecting electromagnet (6) and for increasing the speed of the current change in the scanning winding (8) of the scanning electromagnet (7) as the electron beam moves in the opposite direction.</p> |
