Guoxing Xia: Proton-driven plasma wakefield acceleration, AWAKE at CERN

Friday, 2 March 2018 from to (Europe/London)
at Schuster ( 54-6-6.40 - Niels Bohr Common Room )
Description
Plasma, the fourth state of matter can sustain very large electric fields due to its intrinsic property. This strong electric field can be harnessed for a much more efficient particle acceleration. Since its inception in 1979, plasma-based accelerators have achieved tremendous progress in the last almost four decades. Laser wakefield acceleration (LWFA) has routinely achieved GeV beam energy in centimeter long plasma channel. Electron beam driven plasma wakefield acceleration (PWFA) has successfully demonstrated the energy doubling of a 42 GeV SLC electron beam at SLAC and achieved the high efficiency acceleration for electrons and positrons, respectively. The new plasma-based acceleration experiment, so-called AWAKE at CERN is currently coming online and will be demonstrating the proton-driven plasma wakefield acceleration. In this talk, I will introduce the basic principles and the development of proton-driven plasma wakefield acceleration scheme. The current status of the AWAKE experiment and its future perspective will also be discussed.
