Abstract

A new beam delivery system has been developed to explore the feasibility of extending the energy reach of Compact Linear Collider (CLIC) to 7 TeV, either through an extension of existing CLIC linacs or by integrating novel acceleration technologies. This study provides key insights for the design of future multi-TeV collider concepts, including a potential 10 TeV plasma-wakefield acceleration-based collider. Particular emphasis is placed on developing a more compact final focus system capable of achieving a luminosity higher than that of previous designs. An in-depth analysis of higher-order optical aberrations and their impact on beam size and luminosity performance is presented.
