A magnet/target assembly 1 comprises a target 2 consisting of a plurality of (virtual) segments 2.1, 2.2, 2.3, 2.4, 2.5, 2.6 arranged side by side, each of them extending along the longitudinal axis x of the target 2. Each of the plurality of target segments 2.1, 2.2, 2.3, 2.4, 2.5, 2.6 has a magnet system 3.1, 3.2, 3.3, 3.4, 3.5, 3.6 attributed to the respective target segment. In an embodiment of the target/magnet assembly 1 according to the present invention the magnet systems 3.1, 3.2, 3.3, 3.4, 3.5, 3.6 are arranged mutually offset relative to their respective adjacent magnet systems 3.1, 3.2, 3.3, 3.4, 3.5 and 3.6, respectively, while scanning the target segments 2.1, 2.2, 2.3, 2.4, 2.5 and 2.6, respectively. Particularly, the first magnet system 3.1, the third magnet system 3.3 and the fifth magnet system 3.5 are a first group of magnet systems moving parallel and synchronously with each other, and the second magnet system 3.2, the forth magnet systems 3.4 and the sixth magnet system 3.6 are a second group of magnet systems moving parallel and synchronously with each other. The first, third and fifth magnet systems 3.1, 3.3, 3.5 are alternately arranged with the second, forth and sixth magnet systems 3.2, 3.4 and 3.6, respectively, in the lateral direction y of the target 2. The paths of movement of the magnet systems are arranged parallel. The first and second groups of magnet systems 3.1, 3.2, 3.3, 3.4, 3.5, 3.6 are arranged offset in a longitudinal direction x of the target 2, i.e. arranged with a distance d between the groups in the longitudinal direction x of the target 2. |
