Abstract :
Recent advances in methods of computing magnetic fields have made it possible to study the field in the end region of the SSC (Superconducting Super Collider) quadrupole magnet in detail. The placement of conductor in the straight section, away from the ends, was designed to produce a practically pure quadrupole field in the two-dimensional sense. The ends of the coils were designed to produce a practically pure quadrupole field in the integral sense using a method that ignores the presence of the iron yoke. Subsequently, the effect of the presence of the yoke on the field was analyzed. The authors present the end configuration together with the computed integrated multipole components, local multipole components, and local field components. A comparison with measurements is included
