Detector Challenges of the strong-field QED experiment LUXE at the European XFEL

The LUXE (Laser Und XFEL 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 a power of up to 350 TW. The experiment will measure the spectra of electrons, positrons and photons in expected ranges of $10^{-3}$ to $10^9$ per 1 Hz bunch crossing, depending on the laser power and focus. These measurements have to be performed in the presence of a low-energy high radiation background. To meet these challenges, for high-rate electron and photon fluxes, the experiment will make use of dedicated physics-driven detectors at specific locations downstream of the interaction point.
