Abstract

1280011 Ion beam apparatus UNITED KINGDOM ATOMIC ENERGY AUTHORITY 19 Jan 1970 [5 Feb 1969] 6288/69 Heading H1D An ion beam separator, e.g. for separating isotopes, comprises a curved ion beam passageway 14 and a deflecting magnet 14 including polepieces 27 located either side of passageway 14 and being curved to conform to the shape of the passageway. At least one polepiece 27 has a pole tip 35, 36 movable with respect to the centre line of the passageway. The deflecting electromagnet 15 as a whole may be mounted on four ball castors, two of which are shown at 28, 29, and two of these castors run in a guide track 31, a lead screw 33 and drive wheel 34 being provided to move the magnet 15 parallel to track 31, in the directions of arrows A. The pole tips 35, 36 are thick discs preferably in the shape of a major segment of a circle which fit into shaped recesses in the polepiece 27. This adjustment of the position of the electromagnet 15 and the end faces of the polepieces 27 makes it possible during operation of the separator to vary the dispersion, the focal position, the convergence and the vertical or Z focusing of the ion beam 11. The ion source used may be that described in Specification 1,280,012.
