As a future upgrade option of the ISIS neutron and muon source, we consider FFA as a proton driver. Vertical excursion FFA (vFFA) was chosen because of compact and less complex structure of the main lattice magnets although the maximum field is relatively high. As a proof of principle of the vFFA concept, a prototype machine to accelerate from 3 to 12 MeV is being designed. We will discuss the design principle, code benchmarking, beam dynamics of the strong transversely coupled optics and the current status of hardware R&D.
