“…5(c)]. In contrast, Traveling-Wave Electron Acceleration, combined with upcoming 10-PW-scale laser systems currently under construction [63], has the potential of accelerating at 10 19 cm −3 density electron bunches with tens of pC charge to the energy frontier at TeV energies.…”

Compact electron accelerators are paramount to next-generation synchrotron light sources and freeelectron lasers, as well as for advanced accelerators at the TeV energy frontier. Recent progress in laserplasma driven accelerators (LPA) has extended their electron energies to the multi-GeV range and improved beam stability for insertion devices. However, the subluminal group velocity of plasma waves limits the final electron energy that can be achieved in a single LPA accelerator stage, also known as the dephasing limit. Here, we present the first laser-plasma driven electron accelerator concept providing constant acceleration without electrons outrunning the wakefield. The laser driver is provided by an overlap region of two obliquely incident, ultrashort laser pulses with tilted pulse fronts in the line foci of two cylindrical mirrors, aligned to coincide with the trajectory of the accelerated electrons. Such a geometry of laterally coupling the laser into a plasma allows for the overlap region to move with the vacuum speed of light, while the laser fields in the plasma are continuously being replenished by the successive parts of the laser pulses. Our scheme is robust against parasitic self-injection and self-phase modulation as well as drive-laser depletion and defocusing along the accelerated electron beam. It works for a broad range of plasma densities in gas targets. This method opens the way for scaling up electron energies beyond 10 GeV, possibly towards TeV-scale electron beams, without the need for multiple laser-accelerator stages.

“…Some other experiments, like Astra-Gemini laser facility [5,6] also studied this region. There are few more experiments, European Extreme Light Infrastructure (ELI) [7] and LUXE [8][9][10] that are planned to study SFQED. The parameter space where these experiments reached or are expected to reach is summarized in fig.…”

The LUXE experiment aims at studying high-field QED in electron-laser and photon-laser interactions, with the 16.5 GeV electron beam of the European XFEL and a laser beam with power of up to 350 TW. This experiment will use one electron bunch out of 2700 bunches per train from XFEL. The experiment will measure the multiplicity spectra of electrons, positrons and photons in expected ranges of 10 −3 to 10 9 particles per 1 Hz bunch crossing, depending on the laser power and focus. These measurements have to be performed in the presence of low-energy high radiation-background. To meet these challenges, for high-rate electron and photon fluxes, the experiment will use Cherenkov radiation detectors, scintillator screens, sapphire sensors as well as lead-glass monitors for backscattering off the beam-dump. A four layer silicon-pixel tracker and a compact electromagnetic tungsten calorimeter with GaAs sensors will be used to measure the positron spectra. The layout of the experiment and the expected performance under the harsh radiation conditions will be presented. Beam tests for the Cherenkov detector and the electromagnetic calorimeter were performed at DESY recently and results will be presented. The experiment received a stage 1 critical approvement (CD1) from the DESY management and is in the process of preparing its technical design report (TDR). It is expected to start running in 2025/6.
