Research Abstract

The measurement system for neutron and photon production cross section for several hundred MeV region with high efficiency has been developed. The BGO inorganic scintillator 5.08 cm long and 5.08 cm in thickness was adopted as a detector. The difference of signal decay time of the detector was utilized to separate neutron and photon events. The measurement system had higher efficiency of about 1.8 times than the system with the larger liquid organic scintillator.
