The LUXE experiment (Laser Und XFEL Experiment) is a new experiment in
planning at DESY Hamburg using the electron beam of the European XFEL. LUXE is
intended to study collisions between a high-intensity optical laser and up to
16.5 GeV electrons from the Eu.XFEL electron beam, or, alternatively,
high-energy secondary photons. The physics objective of LUXE are processes of
Quantum Electrodynamics (QED) at the strong-field frontier, where QED is
non-perturbative. This manifests itself in the creation of physical
electron-positron pairs from the QED vacuum. LUXE intends to measure the
positron production rate in a new physics regime at an unprecedented laser
intensity. Parasitically, the high-intensity Compton photon beam of LUXE can be
used to search for physics beyond the Standard Model.
