Compact Superconducting Magnet for Linear Accelerators

Abstract

New Linear Accelerators based on superconducting radiofrequency (SCRF) cavities need compact and efficient superconducting magnet packages to focus and steer electron or proton beams. These magnets should be combined with SCRF cryomodules and installed inside or between them. A recent activity in this area was directed by FNAL-KEK collaboration to splittable conduction cooled magnets. Several magnet prototypes were built and successfully tested. These magnets were designed for high energy beams used in ILC, and Project-X. Nevertheless, there is an interest to explore splittable conduction cooled magnets for new accelerators: FNAL ASTA and PIP-II, KEK STF, SLAC LCLS II. The paper describes a conceptual design of splittable conduction cooled superconducting magnet which could be mounted inside SCRF cryomodule. The magnet package combines the quadrupole magnet and dipole correctors. The presented magnetic design confirms the specified magnet package parameters.
