Abstract

This paper describes the problem of ion RF focusing in the axisymmetric RF field involving one synchronous and several nonsynchronous harmonics. The influence of nonsynchronous harmonics on ion beam dynamics is studied by means of a 3D effective potential, which is obtained for the smooth approximation. The motion equation is presented in Hamiltonian form. The possibility of simultaneous transverse focusing and phase stability for an accelerating ion beam in the RF field without the synchronous harmonic is shown
