installed the nation’s first 50,000-volt electron microscope in Faculty of Science in 1965. This was followed by the introduction of a 1 million-volt electron microscope to Faculty of Engineering in 1972, and a 1.25 million-volt ultra-high voltage electron microscope in 1982.
The technologies gained during development of the first electron microscope triggered subsequent research and development of ultra-high voltage electron microscopes. This culminated in a Japanese manufactured electron microscope being adopted overseas. Research of ultra-high voltage electron microscopes continues to flourish today.
The research of ultra-high voltage electron microscopes conducted at Nagoya University is applied to a wide range of fields and also includes joint development of new equipment with institutions involved in applied research and development of equipment. Equipped with scanning functionality in addition to its high penetration power and detection efficiency, the ultra-high voltage electron microscope installed in 1982 offered the ability to observe amorphous specimens without irradiation damage, as well as the analysis of localized areas of specimens.The device has attracted attention worldwide as it offers functions not available with conventional equipment. Sharing the equipment among all universities has produced prodigious results, enabling Nagoya University to play a key role in the Tokai area. A reaction science ultra-high voltage STEM has now been added, and it is expected to dramatically enhance the role played by the university as a next-generation nanomaterial analysis center.
The facility is operated as a joint annex to the research center of Nagoya University Institute of Materials and Systems for Sustainability.
