Design Study of the Multipole Corrector Magnet for SIS 100

A design study of the multipole corrector magnet for the SIS 100 is in progress. This magnet, which has to integrate functions of a quadrupole, a sextupole and an octupole magnet, contains nested three windings to save longitudinal space in the accelerator ring. Although the windings are made from a Nuclotron type cable as for the SIS 100 main dipole magnet, insulated superconducting wires which are connected in series to allow low current operation, are used for the cable. In this paper, we describe the design principle and mechanical structure of the magnet and present computation results.
