Query: The potential for a high power FFAG proton driver for ADS   Fixed-field alternating gradient accelerators are promising candidates for
next-generation 10 MW-class high power proton drivers. Recent advances in
lattice design of non-scaling FFAGs have progressed toward both isochronicity
and chromatic correction. The resulting 1 GeV non-scaling FFAG design may be
able to support a continuous (CW) beam with far lower peak current than the
pulsed alternative. A 6-cell non-scaling FFAG design is described and recent
work in modeling 3D space charge using the OPAL framework is presented,
including fixed energy studies and beam dynamics with fast acceleration in the
so-called serpentine channel.
