“…Further details on the spectrometer development and the Monte Carlo simulations of its response will be provided in a forthcoming publication [24]. Knowing the HENSA response, which depends on the efficiency of each detector as a function of neutron energy, a deconvolution procedure allows to combine the neutron rates measured by every counter to deduce both the absolute value and spectral shape of the neutron flux [16][17][18]23]. HENSA employs nuclear digital electronics.…”

We report results on the long-term variation of the neutron rate at the Canfranc Underground Laboratory, of importance for the rare event searches located there. The measurement campaign was performed employing the High Efficiency Neutron Spectrometry Array (HENSA) mounted in Hall A and lasted 412 live days. The present study is the first long-term measurement of the neutron rate with sensitivity over a wide range of neutron energies (from thermal to 10 GeV) carried on in any underground laboratory so far. Data on the environmental variables inside the experimental hall (radon concentration, air temperature, pressure and humidity) were also acquired during all the measurement campaign. We have investigated for the first time the evolution of the neutron rate for different energies of the neutrons and its connection with the ambient variables.

We report results on the long-term variation of the neutron counting rate at the Canfranc Underground Laboratory, of importance for several low-background experiments installed there, including rare-event searches. The measurement campaign was performed employing the High Efficiency Neutron Spectrometry Array (HENSA) mounted in Hall A and lasted 412 live days. The present study is the first long-term measurement of the neutron rate with sensitivity over a wide range of neutron energies (from thermal up to 0.1 GeV and beyond) performed in any underground laboratory so far. Data on the environmental variables inside the experimental hall (radon concentration, air temperature, air pressure and humidity) were also acquired during all the measurement campaign. We have investigated for the first time the evolution of the neutron rate for different energies of the neutrons and its correlation with the ambient variables.

This work deals with the characterization of the neutron flux in hall B of the Canfranc Underground Laboratory (LSC) employing the High Efficiency Neutron Spectrometry Array (HENSA). 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 neutron 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.
