Low-Energy Proton Driver for a Neutrino Factory

In contrast with other designs where the proton driver of a muon collider of of a neutrino factory is a synchrotron of energy up to 50 GeV, it is shown that a low-energy and high-power system inspired by neutron spallation sources can meet the requirements of a neutrino factory. Such a system consists of a 2 GeV linac, a fixed field accumulator that produces an adequate time structure and a compressor that reduces the bunch length to the final value of a few nanoseconds.
