The LUXE experiment will explore the uncharted territory of strong field quantum electrodynamics (SFQED) in e-laser and γ-laser interactions at an effective field strength at and above the Schwinger limit. In this regime, non-linear and non-pertubative effects are expected to appear in the production rates of electron-positron pairs. Hence, the number of electron-positron pairs and their energy distribution in e-laser and γ-laser interactions are key characteristics to probe SFQED. In the LUXE experiment the positrons and electrons originating from non-perturbative QED processes (trident production in e-laser, from the Breit-Wheeler process γ-laser and more) will be measured in different detector systems. The central systems consist of two tracker followed by one electromagnetic calorimeter each.
Two electromagnetic calorimeters of the LUXE experiment, called ECAL-e and ECAL-p, are designed as sampling calorimeters using silicon sensors and tungsten absorber plates. ECAL-p will measure the number of positrons and their energy in e-laser and γ-laser interactions and ECAL-e, the same quantities for electrons in γ-laser interactions. In addition, the calorimeters will be used for the cross-calibration of the energy scale with the tracker.
The workshop will focus on the ECAL construction, the mechanical structure, the sensors, the front-end electronics and the data acquisition, as well as simulations and previous testbeam data analysis and results.
Looking forward to see you in Krakow in September!
