LUXE-NPOD background estimation — Torben Ferber, Alexander Heidelbach, Markus Klute, •Raquel Quishpe, and Nicolo Trevisani — Karlsruhe Institute of Technology, Karlsruhe, Germany

The proposed LUXE experiment at the European XFEL at DESY will produce high-intensity electron-laser interactions to study QED in the non-perturbative regime. These interactions have as a secondary product a large flux of photons with energy up to a few GeV. The photons are then directed onto a physical dump allowing the production of axion-like particles (ALPs) in a region of parameters never probed before. The ALPs produced will decay into pairs of photons detected by an electromagnetic calorimeter. One of the challenges for ALPs searches at LUXE is to reduce the background of neutrons and non-resonant photons reaching the calorimeter. We present a systematic simulation study with different dump materials and depths we carried out in the quest of the best balance between signal acceptance and background suppression.
