ABSTRACT:
To make a gradient coil, it is decided to cut the conductors of this coil out of a plate. Thus flat conductors can be used. This helps reduce the self-inductance of the coil to be made. The coil is, moreover, optimized. A calculation is made of the coefficients of the breakdown into spherical harmonics of the field created by the coil. The coil's structure is modified so as to cancel those coefficients of this breakdown which generate a divergence in this field. It is shown that, in this way, the solution is an optimum one.
