Quantum Radiation Energy Lab
Machine-translated · View original
The lab conducts research on free-electron lasers and renewable energy.
AboutAbout the lab
Creating new light with high-brightness electron beams
The lab develops quantum radiation sources that use high-brightness electron beams and studies their applications.
At the Uji Campus, the lab has developed its own compact mid-infrared free-electron laser facility (KU-FEL) and makes it available to users both inside and outside the university.
The lab also conducts international collaborative research on introducing renewable energy in the ASEAN region.
Key terms
- Free-electron laser
- A wavelength-tunable laser produced by making an electron beam from an accelerator interact with light
- Phonon
- A collective vibration of atoms in a crystal
- Gamma rays
- Electromagnetic waves with very high energy
ResearchResearch themes
The lab develops quantum radiation sources that use high-brightness electron beams, studies their applications, and conducts international collaborative research on implementing renewable energy in the ASEAN region.
*Illustrative imageKyoto University's Free-Electron Laser, KU-FEL
The lab has developed KU-FEL, a high-power, wavelength-tunable laser operating in the mid-infrared range of 5–20 μm, and uses it for basic research on energy materials. It has achieved the world's highest extraction efficiency among oscillator-type free-electron lasers, and the lab is also pursuing research on selectively exciting phonons.
*Illustrative imageIsotope Imaging for Nuclear Safety
The lab is developing a method to quantitatively measure the abundance ratio of isotopes inside materials, using gamma rays produced by laser Compton scattering and shaped into a beam with a flat spatial distribution.
*Illustrative imageIntroducing Renewable Energy in ASEAN
Since 2016, the lab has combined social science methods to investigate how electrification projects in Southeast Asia affect people's quality of life and social inequality, and it also works on research on energy justice.
