Abstract

The use of a passive superconductor to correct the magnetization sextupole and decapole in Superconducting Super Collider (SSC) dipoles appears to be promising. The results of a series of experiments on passive superconductor correctors in 1-m-long dipole magnets are presented. Reduction of the magnetization sextupole by a factor of 5-10 has been achieved using the passive superconductor correctors. The magnetization decapole was also reduced. The passive superconductor correctors reduced the sextupole temperature sensitivity by an order of magnitude. Flux creep decay was partially compensated for by the correctors
