Neutron spectrometry in a mixed field of neutrons and protons with a phoswich neutron detector: Part II: application of the phoswich neutron detector to neutron spectrum measurements

Using the developed phoswich neutron detector, the neutron energy spectra in a neutron–proton mixed field and in a neutron and heavy-charged-particle mixed field were measured using an unfolding method coupled with the obtained neutron response functions. The photon and proton energy spectra were obtained separately in these mixed fields using the photon response functions and the proton light yield calibration given in the preceding work. The measured spectra were compared with the spectra obtained by the TOF (time-of-flight) method.
