Overview of Research Group, Goals and Purposes:

Our research group 'Infared spectroscopy with synchrotron radiation source' have the following missions. (1) Promotion and further developmment of infrared synchrotron radiation research. (2) Collaborative research and study activities with communities using other infrared and teraheratz sources. The infrard (IR) beamline BL43IR at SPring-8 covers a spectral range between the far and near infrared (between 100 and 10000 cm-¹). In this spectral range, the synchrotron radiation (SR) has about 2 orders of magnitude greater birilliance than the conventional IR source. Taking advantage of this high birilliance, IR microscopic studies and IR studies under extereme conditions such as high pressure and high magnetic field are actively carried out. The application fields include solid state physics, chemistry, biology, materials science, archiology, and medical science. In addition, near-field IR spectroscopy apparatus has also been developed. We will further develop the research activities and will promote the IR SR research for the prospective users in a wide range of fields.

At the next generation SR facilities worldwide, the use of IR SR is expected to meet some difficulties due to the limited extraction angle of SR from the electron storage ring chamber. Therefore, possibilities of combined use of IR SR and other X-ray/soft X-ray beamlines at SPring-8 will be considered and discussed.
Furthermore, since other kinds of IR and teraheartz sources with high brilliance and power are available, combined use of IR SR and these sources are also considered and discussed.
