Abstract: Simulations have shown that a high energy, short and intense proton beam candrive a large amplitude plasma wave and accelerate an electron beam to theenergy frontier in a single plasma channel. To verify this novel idea, aproof-of-principle demonstration experiment is now being planned. The idea isto use the available high energy proton beams either from the ProtonSynchrotron PS or the Super Proton Synchrotron SPS at CERN, to shoot thebeam into a plasma cell and to excite the plasma wakefield. A strong densitymodulation due to the excited plasma wakefield is produced for a long drivebeam and this modulated beam in turn produces a high electric field. Theproposed experimental setup is introduced in this paper. The interactionsbetween the plasma and the proton beam are simulated and the results arepresented. The compression of an SPS bunch is also discussed.
