Soft X-ray actual environmental analysis
Beamline:Public Beamlines: BL27SU, BL47XU
Contract Beamlines: BL07LSU, BL17SU
Overview of Research Group, Goals and Purposes:
Soft X-ray spectroscopic analytical techniques are one of the best techniques for the determination of the electronic structures and of the chemical state of materials. However, so far, the application of soft X-ray analysis has been highly restricted. Since soft X-rays are largely absorbed by air under ambient pressure, it is standard procedure to perform soft X-ray analysis under high vacuum. Although the high-vacuum chamber produces an ideally clean environment for the sample, chemically significant phenomena take place under ambient pressure, such as the coexistence of water and oxygen gas. In recent years, demands to study samples under higher-pressure regions (1~760 mbar) are one of the active areas of modern research in soft X-ray analysis.
To overcome the current limitations, we propose establishment of research group aiming at the development of novel soft X-ray analytical techniques which make it possible to analyze the materials under the actual environment. The following activities will be carried out in this research group.
The purpose of the group is to create fundamental technologies applicable to various materials in actual environment and to perform pioneering research using soft X-ray beamlines by collaborating with another research groups in SPRUC.
