EFFECTS OF FIELD PERTURBATIONS IN FFAG ACCELERATORS

Technical Report ·
OSTI ID:4662856
Because of the variation of the betatron oscillation frequencies, nu / sub z/ and nu /sub r/, with the amplitude of the osciliation, it is difficult to avoid the resonances excited by perturbing fields. The range of tunes, nu /sub r/ and nu /sub z/, covered by a beam, which includes the useful range of oscillation amplitudes, will contain a large number of perturbation resonances which will affect the betatron oscillations of the particles. The rapid variation of tune with amplitude seems, however, to limit the effect of the perturbation resonances. Detailed results are given for the effects of the nearest linear coupling resonance, which is nu /sub r/ + nu /sub z/ = 18 for the accelerator considered, and which will be one of the stronger resonances excited by the perturbing magnetic field.
