SPIRAL RIDGE CYCLOTRON PARTICLE DYNAMICS APPLIED TO CONVERSION OF THE HARWELL SYNCHROCYCLOTRON

Abstract A theoretical design study for conversion of the Harwell synchrocyclotron to spiral ridge operation is outlined. Effects due to non-linearities in the dynamics have a major influence on the design. The initiation of large radial betatron oscillations at the centre of the machine could have serious consequences, and experimental model studies are now in progress to examine the problem. Apart from this, the suggested conversion should be feasible with careful design and construction.
