Beam Optics Modelling Through Fringe Fields During Injection and Extraction at the CERN Proton Synchrotron

As the beam is injected and extracted from the CERN Proton Synchrotron, it passes through the fringing magnetic fields of the main bending units (MUs). In this study, tracking simulations using field maps created from a 3D magnetic model of the MUs are compared to beam based measurements made throug...

Descripción
Sumario:As the beam is injected and extracted from the CERN Proton Synchrotron, it passes through the fringing magnetic fields of the main bending units (MUs). In this study, tracking simulations using field maps created from a 3D magnetic model of the MUs are compared to beam based measurements made through the fast injection and slow extraction regions. The behaviour of the fringe field is characterised and its implementation in the MAD-X model of the machine is described.
