Multistage laser wakefield accelerators that are coupled with variable-curvature plasma channels make it possible to efficiently accelerate electrons to high energies that exceed dephasing and pump depletion limits.Seamless coupling between laser and particle beams may envisage future energy-frontier colliders of revolutionarily small size and cost.
In the long-standing quest for the fundamental building blocks of nature,in the so-called Standard Model of particle physics,energy-frontier colliders have played a central role in the forefront of research on matter and interactions.
