Using FFAGS for the arcs of recirculating accelerators has the potential to achieve significant cost savings over a multiple-arc design. However, no FFAG arc will have the same path length over its entire energy range. This leads to problems with synchronizing high-frequency RF with the beam on each pass. It has been demonstrated [1] that in fact a reference particle can be accelerated in such a system for an arbitrary number of turns, although the amount of linac required for a given energy gain never falls below a certain nonzero value for a larger number of turns. Here we examine that system in more generality, and begin to address longitudinal phase space acceptance.
