Zusammenfassung:A magnet pole for an isochronous sector-focused cyclotron comprising hill and valley sectors alternatively distributed around a central axis, Z, each hill sector comprises an upper surface bounded by four edges: an upper peripheral edge, an upper central edge, a first and a second upper lateral edges. The upper peripheral edge of a hill sector comprises an arc of circle which centre is offset with respect to the central axis, and which radius, Rh, is not more than 85% of a distance, Lh, from the central axis to a midpoint of the upper peripheral edge, which is equidistant to the first and second upper distal ends (Rh / Lh ‰¤85%).
