Seminarium Fizyki Wielkich Energii

The Faculty of Physics at the University of Warsaw is a member of theinternational LUXE (Laser Und XFEL Experiment) Collaboration. Theproject involves a groundbreaking experiment in the Eu.XFEL laboratoryin Hamburg. It aims to study the Quantum Electrodynamics (QED) in theregime of very strong fields. One of the key elements of the LUXEexperiment is a high-density electromagnetic calorimeter, ECAL-P,designed to precisely measure the energy and spectra of positronsproduced during collisions. The ECAL-P project is being developedwithin the framework of the CERN Detector R&D Collaboration onCalorimetry (DRD-calo).Members of the LUXE collaboration came to Warsaw in September to takepart in the collaboration meeting and the workshop of the ECAL-Pdetector group. The meeting in Warsaw was followed by the DRD-calocollaboration meeting in Ancona. We will report on the activities ofboth collaborations with particular focus on the Faculty of Physicscontribution.
