    Abstract: A DEVICE FOR THE ACHROMATIC MAGNETIC DEFLECTION OF A BEAM OF CHARGED PARTICLES AND AN IRRADIATION APPARATUS USING SUCH A DEVICE An achromatic magnetic deflection device for deflecting by an angle ? between .pi. and 2.pi. a beam of charged accelerated particles having different momentum. This device comprises an electromagnet provided with pole pieces delimiting three contiguous sectors, the whole of these sectors, having an axis of symmetry XX, presenting flat input E and output S faces and common faces F1 and F2 in an arc of a circle, the position, the radius of curvature of these faces F1, F2 as well as the value of the magnetic induction in the sectors being chosen so that the different paths are substantially orthogonal both to faces F1, F2 and to axis XX.
