Scaling FFAG lattices for muon acceleration

摘要

Harmonic number jump acceleration of muon beams in scaling FFAG rings is studied. General considerations about harmonic number jump acceleration lead to the necessity of designing rings with dispersion suppressed insertions, and in which both μ~+ and μ~- can be circulated in the same direction. Design principles of such a scaling FFAG ring are described. Example of a 3 to 10 GeV lattice is given, and 4D acceleration tracking is done in it.
