Development of a cosmic muon and neutron veto system for IAXO and BabyIAXO — •Dhruv Chouhan, Elisa Ruiz-Chóliz, and Matthias Schott — Johannes Gutenberg University of Mainz, Germany

The International Axion Observatory (IAXO) experiment is a large-scale helioscope aimed at searching for axions and axion-like particles (ALPs) produced in the Sun. As a first step, the BabyIAXO was proposed as a smaller scale helioscope that will reach a sensitivity on the axion-photon coupling of 1.5*10-11 GeV-1 for masses up to 0.25 eV, covering a very interesting region of the parameter space. To detect the axion signal, a very low background x-ray detector design is required. This talk will focus on the development of the BabyIAXO veto system for cosmic rays based on light-guided organic plastic scintillators with Silicon Photo Mutiplier sensors.
