Advanced Research Center for Beam Science

We promote the development of quantum beams and ultimate space-time analysis and their applications to physics of nuclei, materials and plasmas.

Our research is an experimental research for unstable nuclei, such as the precision measurements for a nuclear charge density distribution and a mass, by means of the electron and heavy-ion accelerators to contribute to the studies for nucleosynthesis in universe and establishing the equation of state for nuclear matter.

Ultra-intense and ultra-short pulse laser-matter interactions and their applications are studied. The physics of laser produced radiation and its application on analytical science are investigated. Using laser produced plasma electrons, ultrafast electron diffraction and deflectometry are developed. The interactions of femtosecond laser pulses with surface plasmas are studied to interpret the physics of laser nano-ablation, self-organization of periodic structures on surfaces, phase transition and so on, and the new material science of laser nano processing and material reforming is developed.

To investigate the structure of the interface in thin films, surface chemical reactions, and the formation of nanomaterials, we utilize direct imaging of the structural arrangement of atoms or molecules by high-resolution electron microscopy and scanning probe microscopy. Local electronic structure analysis and elemental mapping are also performed to explore chemical information by measuring the energy of inelastically scattered electrons.

This laboratory studies the structural biology about the relationships between protein structures and their functions and properties based on the crystal structures determined by X-ray analyses. The main research themes are elucidation of the enzymatic reaction mechanism and the adaptation strategy of proteins from thermophilic or cold-adapted bacteria.
