TL;DR

This paper explores the potential of using modulated proton bunch driven plasma wakefield acceleration for future high-energy colliders, discussing design considerations for electron-positron and electron-hadron colliders based on CERN infrastructure.

Contribution

It introduces a scheme for plasma wakefield acceleration using self-modulated proton bunches and discusses its application to future collider designs.

Findings

Proton-driven plasma wakefield can accelerate electrons to high energies in a single stage.

Design considerations for future colliders using this technology are analyzed.

Potential integration with existing CERN infrastructure is discussed.

Abstract

Recent simulation shows that a self-modulated high energy proton bunch can excite a large amplitude plasma wakefield and accelerate an externally injected electron bunch to the energy frontier in a single stage acceleration through a long plasma channel. Based on this scheme, future colliders, either an electron-positron linear collider (e+-e- collider) or an electron-hadron collider (e-p collider) can be conceived. In this paper, we discuss some key design issues for an e+-e- collider and a high energy e-p collider, based on the existing infrastructure of the CERN accelerator complex.
