The AITANA group hosts the 1st ECAL-p LUXE workshop

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. This and much more was comprehensively presented and discussed by Dr. Grzegorz Grzelak during his IFIC Seminar (The LUXE – Laser und XFEL Experiment – era of strong fields QED)  which served as appetizer for the workshop and as introduction of the project to the whole IFIC.

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 trackers followed by one electromagnetic calorimeter each. These are the ECAL-p and ECAL-e.

For both calorimeters, the CALICE collaboration and FCAL collaboration propose two different and complementary solutions aiming for high granular systems with two different technological solutions: the fully embedded electronics solution à la CALICE and the ultra-compact solution à la FCAL. Experts from both collaborations and detector concepts will join in Valencia to discuss and plan the overcoming of the different challenges ahead us.
