利用京都大学的固定场交变梯度加速器测量了由107 MeV质子引起的Fe、Pb和Bi靶的双微分厚靶中子产额（TTNYs），用于加速器驱动系统（ADS）的研究和开发以及京都大学临界大会（KUCA）的基础ADS反应堆物理研究。注意，TTNY是使用包括八个中子探测器的中子探测器系统通过飞行时间方法获得的;每个探测器具有小的EJ-301液体有机闪烁体和光电倍增管。得到的TTNYs进行了比较，计算结果使用Monte Carlo为基础的spectrometry模型（即EST4.6/GEM，Bertini/GEM，JQMD/GEM，和JQMD/SMM/GEM）和评估的高能核数据库，即JENDL-4.0/HE，在粒子和重离子输运代码系统（PHITS）中实现。所有的模型，包括JENDL-4.0/HE，未能预测在探测器角度的高能量峰。比较使用测量的TTNYs和PHITS估算的能量≤20 MeV的能量和角积分散中子产额表明，KUCA的ADS反应堆物理实验的Monte Carlo输运模拟将适用于KUCA。
Double-differential thick target neutron yields (TTNYs) for Fe, Pb, and Bi targets induced by 107-MeV protons were measured using the fixed-field alternating gradient accelerator at Kyoto University for the research and development of accelerator-driven systems (ADSs) and fundamental ADS reactor physics research at the Kyoto University Critical Assembly (KUCA). Note that TTNYs were obtained with the time-of-flight method using a neutron detector system comprising eight neutron detectors; each detector has a small EJ-301 liquid organic scintillator and photomultiplier tube. The TTNYs obtained were compared with calculation results using Monte Carlo-based spallation models (i.e. INCL4.6/GEM, Bertini/GEM, JQMD/GEM, and JQMD/SMM/GEM) and the evaluated high-energy nuclear data library, i.e. JENDL-4.0/HE, implemented in the particle and heavy ion transport code system (PHITS). All models, including JENDL-4.0/HE, failed to predict high-energy peaks at a detector angle of. Comparing the energy- and angle-integrated spallation neutron yields at energies of ≤20 MeV estimated using the measured TTNYs and the PHITS indicated that INCL4.6/GEM would be suitable for the Monte Carlo transport simulation of ADS reactor physics experiments at the KUCA.
