Most accelerator magnets for applications in the field range up to 10 T utilize NbTi superconductor and a cosine theta coil design, For fields above 10 T, it is necessary to use Nb(3)Sn or other strain sensitive superconductors and other coil geometries that are more compatible with these materials. This paper describes our recent efforts to design a series of racetrack coil magnets that will provide experimental verification of an alternative magnet design philosophy, with the near-term goal of reaching a field level of approximately 14 T. The conductor and fabrication issues relevant to building high field, racetrack dipoles utilizing Nb(3)Sn superconductor and a wind and react approach will also be discussed
