Conceptual design study of Nb3Sn low-beta quadrupoles for 2nd generation LHC IRs

摘要

Conceptual designs of 90-mm aperture high-gradient quadrupoles based on the Nb3Sn superconductor, are being developed at Fermilab for possible 2nd generation IRs with the similar optics as in the current low-beta insertions. Magnet designs and results of magnetic, mechanical, thermal and quench protection analysis for these magnets are presented and discussed.
