MULTI-TEV UPGRADE CONCEPT FOR INTERNATIONAL LINEAR COLLIDER BASED ON PROTON DRIVEN PLASMA ACCELERATION

Seryi, A. (SLAC)

Abstract: The International Linear Collider ILC, designed by the Global Design Effort (GDE), will provide electron-positron colliding beams with Center of Mass (CM) energy up to 500 GeV. The ILC is based on superconducting accelerator technology and will provide luminosity in the range of 10E34 cm-2s-1. An upgrade of the ILC to 1 TeV CM energy is, in principle, considered by the GDE and would involve lengthening of the tunnels and installation of additional superconducting linear accelerator sections to double the energy of the beams. We suggest evaluating a different approach to the ILC upgrade, which, provided that technical challenges be solved, may open a path for ILC to much higher energy of several TeV, potentially exceeding the energies considered for the electron-positron collider CLIC or for the muon collider. This approach is based on use of proton-driven plasma acceleration when proton bunches are accelerated together with electrons and positrons, and special beamline arrangements are used to bring bunches together to the plasma sections. Separation and merging of the proton and electron or positron beam, as well as the control of phase slippage of the proton beam, are performed with use of special double path chicanes. The latter can also be optimized to provide ballistic compression of the proton bunches during acceleration. This paper describes the overall concept; the functions of the beamlines; the layout; and the tentative, not-optimized parameters of the ILC upgraded to 1 TeV CM. The concept can potentially be extended to the multi-TeV range.
