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.

  1. Promotion of applied soft X-ray analysis under actual environment.
    We will promote the application of soft X-ray analytical techniques to the materials under actual environment. For this purpose, it is needed to optimize the conventional techniques or develop a novel technique to the unexplored research field.
  2. Encouragement of multi-beamline utilization and of interaction with researchers in the different field from soft X-ray spectroscopy.
    So far, complementary use of soft-X-rays beamline and hard X-ray beamline is restricted, since the specific techniques are necessary for soft X-ray experiments. We will encourage the multi-beamline utilization including soft X-ray beamlines, and generate a synergistic effect.
  3. Proposal about next-generation soft X-ray beamline and light source.
    Middle size 3-rd generation synchrotron light sources are building around the world, and some of beamline overwhelm performance of soft X-ray beamlines in SPring-8. We will discuss about the next generation soft beamline and light source to possess the world's highest competitiveness.

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.
