Neutron Activation Experiments and Elemental Analysis Experiments by Gamma-ray Spectrometry Using Electron Accelerator Driven Neutron Source at Hokkaido University
1. Summary
Quantum beams such as neutron beams are used in materials science, life science, nuclear physics, particle physics, industrial applications, cancer therapy, and pharmaceutical applications. Among these, elemental analysis experiments using neutron activation and gamma-ray spectrometry are used for nondestructive elemental analysis of valuable samples such as sandstone brought back from asteroids by space probes and ancient cultural heritages. In this practical training, you will learn neutron activation and gamma-ray spectrometry using HUNS (Hokkaido University Neutron Source), an electron linear accelerator-driven pulsed neutron experimental facility of the Graduate School of Engineering, Hokkaido University, which conducts a wide range of academic, industry-academic, and international joint research on demand, including materials research, food research, cultural heritage research, and cosmic ray resistant semiconductor research using neutron beams. The course provides experience in elemental analysis experiments using neutron activation and gamma-ray spectrometry. The program is very basic in content and is designed to be comfortable for beginners. On the other hand, the program is designed to provide a valuable experience for those who are not beginners so that they can experience radiation practice, spectrum analysis, and discussions based on the students' free ideas, surrounded by a different environment and people than usual.
