Name HAGURA Naoto
Official Title Associate Professor
Affiliation Nuclear Safety Engineering, Science and Engineering
Profile I received my degree in 2010 in the field of reactor physics and nuclear data evaluation. The topic of my dissertation was the study of uncertainties of nuclear data in the evaluation of decay heat from spent MOX fuel. After receiving the degree of engineering, I worked for a nuclear power plant manufacturer and joined the Atomic Energy Research Laboratory of Tokyo City University (TCU) as a research assistant in 2013, and was appointed as an assistant professor at the Department of Nuclear Safety Engineering, Faculty of Engineering, TCU in 2015, and as an associate professor in 2020. I am engaged in research on beam applications using electrostatic accelerators.
Research Field(Keyword & Summary)
  1. Development of image processing method to significantly improve the energy resolution of WDS-PIXE

    In the development of reprocessing technology for spent fuel generated by nuclear power generation, one of the objectives is to understand the chemical bonding state of complexes that need to be separated. We will develop a method to dramatically improve the energy resolution of particle-induced X-ray emission spectroscopy (PIXE), a trace element analysis method using ion beams. We will develop a wavelength-dispersive spectroscopic system, which is a method to measure X-ray energy in detail using a spectroscope crystal, combined with image processing techniques such as "bright spot center of gravity processing," "super-resolution processing," and "pixel shifting."
