First results from the HENSA/ANAIS collaboration at the Canfranc Underground Laboratory

The HENSA/ANAIS collaboration aims for the precise determination of the neutron flux that could affect ANAIS-112, an experiment looking for the dark matter annual modulation using NaI(Tl) scintillators. In this work, the first measurements of the neutron flux and Monte Carlo simulations of the neutron spectrum are reported.Peer ReviewedPostprint (published version
