In this study, we considered the measurement of neutron energy spectra from the neutron source (Pu-Be) owned by the Nuclear Research Institute, Kinki University, using unfolding method. CsI scintillators provide sufficient radioactivity even in low-intensity neutron fields, were used it as alternative to activation foils. The response functions of several acrylic plates to the moderation system were calculated by simulation using PHITS. In the future, finally, we will perform activation experiments to obtain neutron energy spectra.
