Description

The development of Energy Recovery Linacs is one of the objectives of the ECFA Accelerator R&D Roadmap established in the 2021 European Strategy for Particle Physics, and in the Recommendations by the European Strategy Group for the 2026 Update [1]. In this talk we present the development of ERLs with a focus on their application to high-energy accelerators. We discuss the present status and technical challenges of ERL, from PERLE at IJCLab, Orsay, to the proposal of the LHeC as a project to bridge the HL-LHC to the next flagship at CERN, for which the successful demonstration of high-current multi-turn ERL at PERLE is an essential milestone. We will also highlight the important synergies between PERLE and FCC in the SRF domain.
