We propose a dielectric-based, multistaged, laser-driven electron linear accelerator structure operating in a vacuum that is capable of accelerating electrons to 1 TeV in 1 km. Our study shows that a GeV/m gradient is achievable using two 100 fs focused crossed-laser beams, repeated every 300 μm, operated at a peak power of 0.2 GW and an energy density of less than 2 J/cm2 on the accelerator structure.
