Within the TANGRA project framework, a new experimental setup has been constructed for the measurement of cross sections of reactions $$(n,X,\gamma)$$ in the interaction of 14.1 MeV neutrons with nuclei. The facility has a special feature: the use of the tagged neutron method. This method enables efficient separation of background and useful events, as well as accurate tracking of the neutron flux. Test measurements were performed on $${}^{28}$$ Si, $${}^{12}$$ C, and $${}^{16}$$ O nuclei, and the results showed satisfactory agreement with available experimental data. This paper presents the features of the setup design and the methodology for processing the obtained experimental data.
