Abstract
An achromatic magnetic deflection device for deflecting by an angle .phi. 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 F.sub.1 and F.sub.2 in an arc of a circle, the position, the radius of curvature of these faces F.sub.1, F.sub.2 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 F.sub.1, F.sub.2 and to axis XX.
