This systematic study has been performed on secondary particle production and its transport through matter by high energy charged particles of 20 MeV to several hundreds MeV/nucleon. The particle spectrometry and cross section measurements have been done by using five hadron accelerators, three AVF cyclotrons at Institute for Nuclear Study, University of Tokyo (INS), Cyclotron and Radioisotope Center, Tohoku University (CYRIC), Takasaki Research Establishment, Japan Atomic Energy Research Institute (TIARA), the separate sector cyclotron at Institute of Physical and Chemical Research (RIKEN), and the heavy ion synchrotron at National Institute of Radiological Sciences (HIMAC).The study has mainly done using the TIARA cycloton and the research activities are classified into the following five contents.(1) Development and characterization of p-Li quasi-monoenergetic neutron fields in the energy range of 20 to 210 MeV,(2) Calibration of the sensitivities and responses of various neutron detectors,(3) Measurements of neutron activation cross sections and neutron-induced charged particle emission cross sections,(4) Experiments of neutron penetration in and through iron, concrete and polyethylene, and neutron leakage through maze,(5) Measurements of thick target yields of neutrons produced by charged particles of several tens MeV/nucleon and several hundreds MeV/nucleon.

这项系统研究是针对 20 MeV 至数百 MeV/核子的高能带电粒子产生的二次粒子及其在物质中的传输进行的。粒子光谱和截面测量是通过使用东京大学核研究所（INS）、东北大学回旋加速器和放射性同位素中心（CYRIC）、日本原子能研究机构高崎研究所的五个强子加速器、三个AVF回旋加速器完成的研究所（TIARA）、理化研究所（RIKEN）的分离扇形回旋加速器、国立放射线科学研究所的重离子同步加速器（HIMAC）。该研究主要利用TIARA回旋子进行，研究活动分为以下五个内容。（1）20至210MeV能量范围的p-Li准单能中子场的开发和表征， (2)各种中子探测器灵敏度和响应的标定，(3)中子活化截面和中子感生带电粒子发射截面的测量(4)中子在铁、混凝土和聚乙烯中的穿透和中子迷宫泄漏实验,(5)几十MeV/核子和几百MeV/核子带电粒子产生的中子粗靶产额测量。
