报告摘要

一一Plasma, the fourth state of matter can sustain very large electric fields for particle acceleration. Since the inception of the concept in 1979, plasma-based accelerators have achieved tremendous progress in the last four decades. Laser wakefield acceleration has routinely achieved GeV beam energy in centimetre long plasma channel. Electron beam driven plasma wakefield acceleration has successfully demonstrated the energy doubling of a 42 GeV Stanford Linear Collider (SLC) electron beam at Stanford Linear Accelerator Centre (SLAC) and achieved the high efficiency acceleration for electrons and positrons, respectively. The new plasma-based acceleration experiment, dubbed as AWAKE (Advanced proton-driven plasma wakefield experiment) at CERN is currently coming online and has been demonstrated the capabilities of this novel plasma acceleration concept. In this talk, I will introduce nowadays’ worldwide high-energy particle accelerators, their current status and future. The basic principles of various plasma-based accelerators will then be focused and discussed. The key milestones achieved so far and the future prospects of plasma accelerators will be presented.
