The world’s first multi-quantum beam HVEM (left)
In 2014, we added an optical system that allows the use of multiple lasers, and developed a multi-quantum beam HVEM that allows in-situ observation at the atomic level under irradiation by multi-quantum beams, including ion, laser and electron beams. We are currently developing an in-situ spectroscopy system.

Nanocrystal growth by UV irradiation (right)
We have succeeded in growing ZnO nanocrystals by irradiating submerged plasma-treated Zn with UV light. We are now promoting research on the growth mechanism and its application.

Appealing points to industry and local governments

The multi-quantum beam HVEM is expected to significantly advance research and development of materials that require high reliability and are intended for use in harsh environments such as space and radiation fields. It is also planned to develop materials that exhibit outstanding electrical and optical properties, magnetism and catalytic activity, and to apply them to life sciences and perform submerged operand observation.
