Muon phase rotation and cooling: simulation work at CERN

We present simulation work performed at CERN and collaborating institutes concerning the muon front-end of a neutrino factory and a possible muon cooling experiment. The front-end in the CERN scheme of a neutrino factory has been revised, eliminating the 44 MHz cavities and starting directly with 88 MHz. Two options for a muon cooling experiment have been studied, one based on the 88 MHz CERN cooling channel, and the other based on the 200 MHz super FOFO channel of the US study II design. A figure of merit for the cooling efficiency is discussed
