ASTeC have been granted a US Patent for a permanent magnet-based variable strength multipole magnet (patent number 8,829,462) which has been developed for the CLIC Linear Collider project at CERN. ASTeC has already built two prototypes which have been successfully tested both at Daresbury and at CERN. The team are now developing new ideas for permanent magnet dipoles with variable field strength, again funded by the CLIC project.
