Abstract
A magnetic deflection system for charged particles, the which includes a coil arrangement for generating a magnetic guide field perpendicular to the plane of the desired orbit so as to guide the particles in the plane S.sub.E of the desired orbit on a deflection path on a deflection radius r.sub.0. The system has two coils which are arranged on top of one another on either side of an area A.sub.0 defined by the direction of the magnetic guide field and the deflection radius r.sub.0 so that the winding faces of the coils extend parallel to area A.sub.0, with two of the coils being disposed above the plane S.sub.E of the desired orbit and two below the plane S.sub.E of the desired orbit. In a preferred embodiment, the coils are composed of at least one double pancake.
