	The Neutrino Factory produces neutrinos by muon decay in a storage ring. Pions are produced by firing high energy protons onto a target. Pions decay to muons, which are captured and accelerated to high energy. The target produces additionally a large background that is deposited in the muon capture front end and subsequent components. The implications of energy deposition in the front end lattice for the Neutrino Factory are addressed. Several approaches to mitigating the effect are proposed and discussed, including proton absorbers, chicane, and shielding.

	The (International Design Report) IDR neutrino factory scenario for capture, bunching, phase-energy rotation and initial cooling of muons produced from a proton source target is presented. It requires a drift section from the target, a bunching section and a phase-energy rotation section leading into the cooling channel. The rf frequency changes along the bunching and rotation transport in order to form the muons into a train of equal-energy bunches suitable for cooling and acceleration. This design is being explored within the IDR cost model. Important concerns are rf limitations and beam losses. Recent experiments on rf gradient limits suggest preferred configurations for the rf within the magnetic fields, and these considerations are incorporated into the front end design.

The (International Design Report) IDR neutrino factory scenario for capture, bunching, phase-energy rotation and initial cooling of muons produced from a proton source target is presented. It requires a drift section from the target, a bunching section and a phase-energy rotation section leading into the cooling channel. The rf frequency changes along the bunching and rotation transport in order to form the muons into a train of equal-energy bunches suitable for cooling and acceleration. This design is being explored within the IDR cost model. Important concerns are rf limitations and beam losses. Recent experiments on rf gradient limits suggest preferred configurations for the rf within the magnetic fields, and these considerations are incorporated into the front end design.
