Development of Contact Soft X-ray Microscopy with Synchrotron Radiation

Soft X-rays with a photon energy of about 1 keV are helpful for biological materials, including carbon, nitrogen, and oxygen, because the K-edges are located in the energy region. Here, we are developing a new soft X-ray microscopy method, namely Contact Soft X-ray Microscopy, where the X-ray transmitted to biological samples is converted to visible light by a scintillator and accumulated by a CCD camera. X-ray Absorption Fine Structure (XAFS) at K-edges are recorded and mapped to a two-dimensional image of chemical components. In this talk, the ongoing development and obtained results are introduced.
