Controlling non-linear effects in circular particle accelerators and the dynamic aperture saga: the case of the CERN LHC Controlling non-linear effects is considered a must for preserving and optimising the performance of circular particle accelerators. The advent of superconducting magnets, whose field imperfections are unavoidable, has opened the field of non-linear beam dynamics. A beneficial exchange with the neighbouring field of dynamical systems started in the late 80ies. In this talk the progress made will be reviewed through the concept of dynamic aperture, which has been a key concept in the long history of the design and specification of the CERN Large Hadron Collider (LHC) ring. |
