Abstract
Pole shoes (3, 4, 5) of magnetically conductive material are provided inside of a first tubular target (2). Outside the target (2), a magnetic flux guide element (7) is provided, which has three pole shoes (8, 9, 10) directed toward the hollow body (1), which are connected to each other by magnets (12, 13). These magnets (12, 13) transmit the magnetic field through the target (2) to the pole shoes (3, 4, 5) inside the target (2) across narrow gaps (6, 11).
