Title:     Zero-chromatic FFAG synchrotrons for muon acceleration

Abstract: The next generation of high-energy physics instruments, if they are in the
form of a Neutrino Factory or a Muon Collider, will require the production
of high-energy muon beams. However, the short lifetime of muons as well as
the generally huge transverse emittances of muon beams make their
acceleration very challenging.

The aim of this study is to provide a new approach to muon acceleration.
The idea is to take advantage of the properties of zero-chromatic Fixed
Field Alternating Gradient (FFAG) synchrotrons, in a way compatible with
the acceleration of this very particular type of beam. Two innovative
acceleration methods allowing constant rf frequency acceleration with
scaling FFAGs are considered. A fundamental understanding of these two
acceleration schemes is developed. Possible designs of 3.6 to 12.6 GeV
muon rings are presented. Particle tracking simulations are used to
demonstrate the expected large 6D acceptance of these two different
schemes. The possibility to improve the baseline design of the Neutrino
Factory using these concepts is finally discussed.
