Front End And HFOFO Snake For a Muon Facility

A neutrino factory or muon collider requires the capture and cooling of a large number of muons. Scenarios for capture, bunching, phase-energy rotation and initial cooling of {\mu}'s produced from a proton source target have been developed, for neutrino factory and muon collider scenarios. They require a drift section from the target, a bunching section and a {\phi}-{\delta}E rotation section leading into the cooling channel. The currently preferred cooling channel design is an "HFOFO Snake" configuration that cools both {\mu}+ and {\mu}- transversely and longitudinally. The status of the design is presented and variations are discussed.
