Accelerator Design Studies for the FCCee Positron Damping Ring and Transfer Line

The electron-positron Future Circular Collider (FCCee) requires a com- plex of accelerators to create, damp and accelerate beams of positrons and electrons. Potential designs for aspects of the positron Damping Ring (pDR) and transfer line are presented in this report. Several options for a bunch compressor in the transfer line between the pDR and following accelerating stage were designed and analysed. The accelerator magnets for use in the pDR were designed and modelled. The models were op- timised to meet the accelerator requirements. Cost and environmental impact were also considered.
