One option for acceleration Muons from 30 to 750 GeV is to use a rapid cycling synchrotrons with frequencies of 400-550 Hz. A lattice has been proposed which employs 8T, 4.2 m long superconducting dipole magnets which are interleaved with 1.8T, 7.5 m long normal conducting dipoles. The present design of the normal conducting dipoles for this lattice is based on grain oriented steel, which possesses good magnetic properties in the direction of the grains. Grain oriented steel however is highly anisotropic, which can potentially lead to field quality problems. In this paper we present an alternative design, which suggests lower losses, a higher peak field and better field quality.

MICE, which is an acronym for Muon Ionization Cooling Experiment, is a technology demonstration which is presently assembled at the Rutherford Appleton Laboratory in Didcot, UK. MICE aims to demonstrate ionization cooling experimentally, which is an essential technology for potential future accelerators such as a muon collider. The MICE channel consists of up to 18 large bore superconducting solenoids, which produce a substantial stray field. This stray field can jeopardize the operation of electrical and electronic equipment in the MICE hall. The concept of a partial flux return yoke has been developed, which reduces the stray field in the MICE hall to a safe level. This paper discusses the engineering design of the partial return yoke.
