Future prospects of accelerator science for particle physics

Original content in review article:

This paper introduces several novel ideas. Section 2.1 presents a possible new parameter set for linear collider ILC, resulting from detailed beam-beam studies, that could reduce its power consumption. Section 2.2 proposes a novel approach to selection of the linear collider parameters to allow for beam energy recovery, which in particular could be performed in suggested dual aperture cryomodules (like LHC magnets) with independent accelerating and decelerating structures. Section 3.2 analyses the challenges of interaction region beam stability and proposes a drastic change to the conceptual design of the linear collider machine detector interface (increasing the L* parameter and placing the final lenses on the stable tunnel floor). Finally, in section 5 the concept of a plasma-acceleration based linear collider is explored, based on beam-beam simulations and other studies necessary to ensure that the parameter set of this collider will be consistent with the design objectives.
