Plasma wakefield acceleration is a promising technology for reducing the size of particle accelerators, and its progress has been demonstrated in the AWAKE program at CERN. The AWAKE collaboration is planning to conduct Run 2 to showcase stable accelerating gradients, preserve electron bunch characteristics, and develop scalable plasma sources. This scheme is expected to provide electron beams for particle physics experiments.
Plasma wakefield acceleration is a promising technology to reduce the size of particle accelerators. The use of high energy protons to drive wakefields in plasma has been demonstrated during Run 1 of the AWAKE programme at CERN. Protons of energy 400 GeV drove wakefields that accelerated electrons to 2 GeV in under 10 m of plasma. The AWAKE collaboration is now embarking on Run 2 with the main aims to demonstrate stable accelerating gradients of 0.5-1 GV/m, preserve emittance of the electron bunches during acceleration and develop plasma sources scalable to 100s of metres and beyond. By the end of Run 2, the AWAKE scheme should be able to provide electron beams for particle physics experiments and several possible experiments have already been evaluated. This article summarises the programme of AWAKE Run 2 and how it will be achieved as well as the possible application of the AWAKE scheme to novel particle physics experiments.
