Abstract

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