The ultimate goal of this measurement is to set a limit on the corresponding effects of the neutron flux in the background of the ANAIS-112 experiment. The preliminary counting rates of two years of measurement are reported. Various data analysis techniques, including pulse shape discrimination, are discussed. The first results on the spectral reconstruction of the neutron flux are also presented.2023http://zaguan.unizar.es/record/13114010.22323/1.441.0312http://zaguan.unizar.es/record/131140oai:zaguan.unizar.es:131140Pos proceedings of science 441 (2023), [7 pp.]by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
