Abstract

In the near future, superconducting magnets with a small beam aperture will be required for high energy proton colliders. When coils are designed to be self arched over a small beam pipe, it simplifies the magnet construction both in the winding procedure and in the field quality control. Fabrication of these coils requires cables with large keystone angles. A new structure of “braid-in-strands” is devised to produce these cables. Two types of magnet coils are studied for use of these cables. The straight section of a magnet has been fabricated as a preliminary test. Strand positions have all been measured on the cross section of the coil. Magnetic field analysis is made on the basis of the position data of the strands.
