摘要: A dispenser for supplying metal vapour to an ion source. The metal is provided in a capsule 17 which may be broken to release the metal by turning knob 16 which causes a capsule housing 12 to move to the right, thus causing the capsule to break against a piston member 21. The piston member 21 communicates with a conduit 3 which in turn communicates with the associated ion source, partly shown under reference 2. A heating mantle 29 is provided to vapourise the metal in the housing 12 so that it can pass from the dispenser, through conduit 3, to the ion source.

摘要: A gas ion source in which a high density electric field is established between a first electrode in the form of a hollow needle 5 through which gas to be ionised may pass and a second extractor electrode 9 which has a through-aperture 10 through which the ions flow on their way to a target (not shown).

摘要: @ A system for incorporation in ion-beam equipment to provide ion species filtering and optional ion beam blanking. The system comprises four magnets 4, 5, 6 and 7 arranged on an axis 1. lnbetween magnets 5 and 6 is arranged a plate 10 having an offaxis aperture 11. The ion beam, shown under reference 2, is caused to converge to a focus on plane 3 where the plate 10 is situated. When the magnets 4-7 are energised, the ion beam is caused to bend in the manner shown in drawing A, the amount of deflection depending upon the charge-to-mass ratio of the ion species within the beam. If constructed correctly, the aperture 11 can thus be arranged to pass only a single ion species, the remainder colliding with and being absorbed by the plate 10. Beam blanking may optionally be achieved by blanking plates 13 which may be used to deflect the ion beam out of the plane of parts A and B of the drawing - this is shown in part D of the drawing where it will be seen that the resultant focal point 17 of the ion beam is displaced away from the aperture 11 so that the whole ion beam is blanked off. Astigmatism introduced into the system may be reduced or eliminated by the use of octopole electrode sets 14 and 15.
