核数据对于聚变堆候选材料的发展是不可或缺的。然而，对MeV能源区的核数据进行基准测试还不够充分。本研究以14 MeV中子源为实验对象，从理论上研究了MeV能区的基准性能。我们对轻到重的材料进行了系统的分析。因此，中子谱的基准性能被证实是可以接受的，而伽马射线的基准性能则不够准确。因此，必须应用频谱移位器。铍作为变形器的性能最好。此外，对在基准性能分析中只考虑最后一次碰撞之前的频谱是否真的可以接受进行了初步审查。有人指出，在基准性能分析中，不仅应平等地考虑最后一次碰撞，而且还应平等地考虑较早的碰撞。
Nuclear data are indispensable for development of fusion reactor candidate materials. However, benchmarking of the nuclear data in MeV energy region is not yet adequate. In the present study, benchmark performance in the MeV energy region was investigated theoretically for experiments by using a 14MeV neutron source. We carried out a systematical analysis for light to heavy materials. As a result, the benchmark performance for the neutron spectrum was confirmed to be acceptable, while for gamma-rays it was not sufficiently accurate. Consequently, a spectrum shifter has to be applied. Beryllium had the best performance as a shifter. Moreover, a preliminary examination of whether it is really acceptable that only the spectrum before the last collision is considered in the benchmark performance analysis. It was pointed out that not only the last collision but also earlier collisions should be considered equally in the benchmark performance analysis.
