ANew DA and TMBased Approach to Design Air-Core Magnets

Air-core magnets are commonly used components of high energy physics and nuclear physics accelerators for guiding charged particle beams. The design of air-core magnet is dominated by the precise placement of current carrying coils. The resulting magnetic field can be obtained by direct application of the Biot-Savart law. A new DA and TM based approach was implemented to describe the current carrying coils and to compute the resulting magnetic field. This new approach provides a unique way to analyze the field uniformity, extract multipole components of the field and to design air-core magnets. We will present this approach and discuss the application of this approach to the design and analysis of multipole magnets for the Super Separator Spectrometer (S) being built at GANIL, France.
