To study the applicability of a new generation scintillation detector LaBr_3 for measurements of neutron capture cross sections for fast neutrons, its fundamental performances, such as energy resolution and response functions, were measured. Calorimeters composed of LaBr_3 scintillation detectors were designed and their performances were evaluated using the Monte Carlo simulation code, where their fundamental data on energy resolutions and response functions were used. The simulation showed that the LaBr_3 based calorimeter works as a powerful tool for the measurements of neutron capture cross sections.

为研究新一代闪烁探测器LaBr3在快中子俘获截面测量中的适用性，测量了其能量分辨率和响应函数等基本性能。设计了由LaBr_3闪烁探测器组成的量热计，并利用其能量分辨率和响应函数的基本数据，用Monte Carlo模拟程序对量热计的性能进行了评价。模拟结果表明，LaBr_3基量热计是测量中子俘获截面的有力工具。
