Characterisation of the n_TOF 20 m beam line at CERN with the new spallation target Pavón-Rodríguez, J. A. García Infantes, Francisco Amar Es-Sghir, Hamza Porras Sánchez, José Ignacio Praena Rodríguez, Antonio Javier Torres Sánchez, Pablo n_TOF Collaboration The n_TOF facility hosts CERN's pulsed neutron source, comprising two beam lines of different flight paths and one activation station. It is based on a proton beam delivered by the PS accelerator impinging on a lead spallation target. During Long Shutdown 2 (LS2) at CERN (2019-2021), a major upgrade of the spallation target was carried out in order to optimize the performances of the neutron beam. Therefore, the characteristics of n_TOF two experimental areas were investigated in detail. In this work, the focus is on the second experimental area (EAR2), located 20 m above the spallation target. Preliminary results of the neutron energy distribution and beam line energy resolution are presented, compared to previous experimental campaigns and Monte Carlo simulations with the FLUKA code. Moreover, preliminary results of the spatial beam profile measurements are shown. 2023-10-18T12:22:56Z 2023-10-18T12:22:56Z 2023-05-26 conference output Pavón-Rodríguez, J. A. et al.
