Magnets for the CERN PS booster transfer line

TRIUMF is building 22 magnets for the CERN PS Booster Transfer Line as part of the Large Hadron Collider (LHC) upgrade. These magnets replace similar existing magnets in the transfer line but have higher fields as the maximum proton energy is being increased from 1 GeV to 1.4 GeV. The magnets, 12 quadrupoles and 10 dipoles, are laminated for pulsed operation with a 1.2 second cycle time. The original magnets operated DC. The new magnets must fit within the existing space envelopes and mate to existing support stands.
