Seminarium Fizyki Wielkich Energii

The seminar will introduce LUXE, "Laser Und XFEL Experiment", currently being developed at DESY in Hamburg, an experiment that aims to use the high-quality electron beam of the European XFEL and a high-power laser.The scientific goal of the experiment is to study quantum electrodynamics in the largely unexplored territory, in the regime of strong fields, close to and beyond the Schwinger limit, revealing the non-perturbative face of QED.In the seminar the scientific case of the experiment will be presented.In particular the details of the nonlinear Compton scattering and nonlinear Breit-Wheeler pair production.The second part will cover the experimental setup of beam extraction from the European XFEL Linac, the requirements for a powerful laser and precise detectors optimized to measure electrons, positrons and photons.
