Advanced Measurement Technology Center

This Institute has developed unique and advanced measurement technologies in the High Voltage Electron Microscope Laboratory, the Research Facility for Advanced Science and Technology, and other facilities of the Institute. The Advanced Measurement Technology Center, which was established in April 2015, aims to explore and develop novel measurement techniques, operate multiuser instruments, provide opportunities for collaborative research, and train highly skilled scientists and engineers. The Center is operated jointly by Nagoya University graduate schools and research centers with ties to this Institute, including the Graduate Schools of Engineering, Science, and Environmental Studies, and the Synchrotron Radiation Research Center, and external institutes, such as the Aichi Synchrotron Radiation Center of the Knowledge Hub Aichi and the National Institute for Fusion Science. The Center is divided into the following five sections: Electron Nanoscopy Section, Electromagnetic Wave Measurements Section, Elementary Particle Measurements Section, X-Ray Spectroscopy Section, Nanofabrication & Characterization Section.

Electron Nanoscopy Section

In this section, techniques for detailed structural analyses and property measurements using electron microscopes are developed. Topics include atomic-level analysis of spatial and electronic structures, precise measurements of nanoscale lattice distortions using convergent beam electron diffraction, three-dimensional structural analysis with electron beam tomography, visualization of electromagnetic fields using electron holography, and analysis of chemical reactions under different gas environments.

Nanospectroscopic Materials Science
In current practical materials related to nanotechnologies, defect formation associated with impurity doping and surface/interface structure control drastically improve their physical properties. Our research group is developing precise nano-area analysis methods using advanced electron spectroscopy/microscopy in combination with 'informatics' techniques to clarify the mechanisms behind the material functions and the guiding principles in the development of novel materials. Our research covers topics from fundamental physics such as measuring magnetic moments in sub-nanometer areas to the practical analysis of materials such as lithium ion batteries, catalysts for purifying automotive exhaust gas, ceramic devices, and ferrite magnets.

Electron Beam Physics
We have developed next-generation electron microscopes using innovative electron beams such as electron vortex beams and spin polarized beams. Our newly developed electron microscopes show the world’s highest level of energy- and time-resolutions, and have been applied to the visualization of high-speed phenomena in nanoscale. Also, we have performed characterization of actual materials such as defect analysis of power devices and operand TEM observation of battery materials by making best use of various electron microscopy techniques.

Electromagnetic Wave Measurements Section

This section is dedicated to the advancement of techniques to control energy systems, such as nuclear fusion using plasmas. Research is focused on developing methods to measure line emissions from atoms and molecules in plasmas and reflected light from
light-emitting bodies and other materials.

Plasma Energy Engineering
Plasma‒material interaction is one of the important tasks for achieving nuclear fusion,
and we are conducting research using plasma devices simulating the fusion conditions to control thermal particles and heat loads and
to understand material damage. In addition, utilizing surface modification by plasmas,
we are trying to fabricate novel nanostructured materials for application as, for example, photocatalysts.

Elementary Particle Measurements Section

This section specializes in the development of muon radiography, which is an applied technology to obtain images inside extremely large structures (e.g., pyramid, nuclear reactor, blast furnace, volcano). This technology makes use of muons, which are elementary particles found in charged cosmic rays from outer space that hit the Earth, and other in-house conceived techniques.
