Abstract
Resonances driven by the error field multipoles in the magnets often show themselves as islands in phase plots of the particle motion. In order to be able to measure the strength of the island resonance, and then to correct it, it is helpful to study how these resonances show themselves. In particular, one can study how the presence of the island resonances distort the tune dependence on the amplitude, and the emittance growth caused by the island resonance. Islands in 4-dimensional phase space, unlike islands in 2-dimensional phase space, are not easy to visualize. This study will show how to visualize the islands in 4-dimensional phase space by studying the tune dependence on the amplitude of the particle motion. These effects are to some extent measureable, and can lead to a way to correct the resonance.
