The SSC Collider Ring Correction Magnet System

  • S. R. Stampke

The correction system for the SSC Collider rings will have about 14,000 superconducting magnetic elements. Linear correctors (dipoles and quadrupoles) are located in spool pieces next to focusing (F) and defocusing (D) main quadrupoles. Systematic multipole correction utilizes nonlinear correctors (sextupoles, octupoles, and decapoles) located at positions (C) near half cell centers as well as in the F and D spools. The basic functions of correction magnets and the dynamics leading to the selected configuration are described. Strength requirements, the number and distribution of correction magnets, and initial prototype efforts at collaborating laboratories are outlined.
