Scaling Laser-Plasma Electron Accelerators to 100GeV-scale Energies using TWEAC and Multi-Petawatt Lasers

Debus, A.; Steiniger, K.; Schramm, U.

The quest for advanced acceleration techniques for providing more compact accelerators is a grand challenge of particle accelerator physics. Addressing this challenge will allow to further scale up energies for high-energy physics, as well as enable accelerator technology to be more commonly available.
Despite tremendous advances in Laser-Plasma accelerators (LPAs) with respect to beam energy, quality, charge and stability, sustaining scalability of compact LPAs to even higher electron energies and more brilliant secondary radiation sources is one of the yet to be solved key challenges of the field.
These limitations can be overcome by TWEAC (Traveling-Wave Electron ACceleration), a novel laser-plasma interaction geometry relying on spatio-temporally shaped ultrashort, high-power laser pulses using existing laser technology. These laser pulses provide "flying" focal regions propagating at tuneable velocities close to the speed of light without the need for external guiding.
Multi-petawatt laser facilities together with TWEAC pave the way towards scalable LPAs on the 100GeV scale without the need for multiple laser-accelerator stages.
