Abstract

1360085 Cyclic particle accelerators THOMSON-CSF 8 Oct 1971 [9 Oct 1970] 47061/71 Heading H1D In an isochronous cyclotron, the annular connecting coils 28, 29, . . . 33 are housed in annular gaps 26, 27 formed between the pole plates 20, 21 and the soft magnetic sectors 3 and 4. As shown, the sectors 3 and 4 are tapered towards the axis of the cyclatron, and are supported at their outer periphery by rings 22 and 23 integral with the pole plates, and at their inner periphery by non-magnetic aluminium spacers 24 and 25. The leads to the coils 28, . . . 33 pass through axially directed, epoxy resin sealed holes in the plates 20, 21 to radial grooves 35, 36 (Fig. 5, not shown).
