Abstract (de)

Eine Multipoleinheit besteht herkömmlich aus einem Trägerrohr (1), einem Gewindering (2), mehreren Magnetringen (3), mehreren Distanzringen (4) und einem Federring. Erfindungsgemäß wird der Aufbau einer Multipoleinheit dadurch vereinfacht, daß der Gewindering so modifiziert wird, daß der Federring überflüssig wird. Dazu weist der Gewindering oder ein am Trägerrohr vorgesehener Anschlag (1a) Federelemente (2a) auf, die die Funktion des herkömmlichen Federrings übernehmen. <IMAGE>
