Apparatus for irradiating the two opposite faces of a target by means of a scanning beam and comprising a magnetic deflection system formed by an electromagnet provided with two pole pieces disposed downstream of the target to be irradiated, the length of the pole pieces corresponding to the amplitude of the scanning beam in such a way that, if theta theta 1+ theta 2 is the total scanning angle, the scanning beam of angle theta 1 impinges on one face of the target, while the scanning beam of angle theta 2 theta - theta 1 is deflected in the magnetic deflection system and irradiates the other face, the polepieces having a face, so-called useful face, facing the other face of the target and comprising several sections with different curvatures for obtaining a reflected beam substantially perpendicular to this other face of the target.
