Abstract

The (International Design Report) IDR neutrino factory scenario for capture, bunching, phase-energy rotation and initial cooling of micro's produced from a proton source target is explored. It requires a drift section from the target, a bunching section and a -E rotation section leading into the cooling channel. The rf frequency changes along the bunching and rotation transport in order to form the 's into a train of equal-energy bunches suitable for cooling and acceleration. Optimization and variations are discussed. An important concern is rf limitations within the focusing magnetic fields, mitigation procedures are described. The method can be extended to provide muons for a micro+-micro < Collider, variations toward optimizing that extension are discussed.
