Abstract
An important step in the development and manufacture of the bending magnets for the proposed superconducting supercollider particle accelerator is measurement of the multipole moments of the magnetic field. This paper describes a method for doing so that makes use of the simultaneous pulsed NMR signal from a large number of coils placed on the diameter of a circle. From the value of the magnetic field thereby measured on the boundary, the multipole moments are obtained. Details of the basic concepts of the method are presented, along with some results of an early test of it.
