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.

研制了一套能测量几百MeV中子和光子产生截面的高效率测量系统。采用长5.08 cm、厚5.08 cm的BGO无机闪烁体作为探测器。利用探测器信号衰减时间的差异来分离中子和光子事件。该测量系统具有比具有较大液体有机闪烁体的系统高约1.8倍的效率。
