Target field design for magic angle gradient coils.
The target field method of designing gradient coils is extended to the case where the gradient producing currents lie on cylinders of a general orientation with respect to the polarizing magnetic field. This provides a general approach for designing coils that require unusual sample geometries such as those required for magic angle spinning (MAS) applications. A detailed example of a magic angle gradient coil set for MAS is given.
