Abstract

1457860 Cyclic particle accelerators ATOMIC ENERGY OF CANADA Ltd 27 March 1975 [31 July 1974] 13005/75 Heading H1D In a neutron beam source for medical use, in which the neutrons are produced by the impact of ions on a target, the ions are accelerated by an isochronous cyclotron having: an iron envelope 15 which also constitutes a magnetic yoke and shield and a radiation shield; a pair of aircored superconducting coils 13 and 14 mounted in the envelope and cooled by the circulation of supercritical helium; an ion orbiting region 19 defined by a resonator 36 formed by a pair of interconnected sector-shaped v.f. electrodes supported on legs 24 and 25 and positioned in two of the valleys 35a and 35c between the four sector shaped flutter poles 34a to 34d formed by raised portions of the iron housing; a target 30 struck by the accelerated ions, the resulting neutrons passing through a window 33 and being collimated by the channel 32 in the iron envelope ; and a support structure 11a, 11b by means of which the complete source can be moved along a substantial arc of a circle. Deuterons or protons, produced by a stream of D 2 or H 2 , respectively, and a tungsten filament, are introduced into the centre of the orbiting region via the tube 21 (Figs. 6a and 6b, not shown); vacuum pump 28 maintains the necessary vacuum; and the lithium or beryllium target 30 is mounted on a tube and may be withdrawn into a vacuum lock for servicing.
