Neutron beam monitors with a wide range of efficiencies, low γ sensitivity, and high time and space resolution are required in neutron beam experiments to continuously diagnose the delivered beam. In this work, commercially available neutron beam monitors have been characterized using the R2D2 beamline at IFE (Norway) and using a Be-based neutron source. For the γ sensitivity measurements different γ sources have been used. The evaluation of the monitors includes, the study of their efficiency, attenuation, scattering, and sensitivity to γ. In this work we report the results of this characterization.
