Summary of Working Group 8: Advanced and Novel Accelerators for High Energy Physics

Abstract

We summarize the conclusions from Working Group 8 of the European Advanced Accelerator Concepts workshop in 2019 (EAAC2019) on the suitability and prospects for using advanced and novel accelerator (ANA) technology for future high-energy physics (HEP) applications. We identify the key technology gaps remaining for the main ANA approaches for building future e+/e- linear colliders and estimate the time scales needed to close them. We also identify synergistic development paths that can be leveraged to achieve key technology demonstration steps through non-HEP applications and through non-lepton-collider HEP applications.
