D01：X-ray Imaging using synchrotron radiation for the studies of hierarchic structure and dynamics in materials
We will develop an SOI area detector for the studies of hierarchic structure and dynamics in materials. The X-ray area detector with a high space resolution of 30 mm pixel is much valuable to investigate new ferroelectric materials for electronics application. With fine pixels of a new detector, we are planning to decide precise position of hydrogen atoms, related to mechanism of the large polarization of a ferroelectric, found in an organic complex. Time response of the domain structure in such a sample by external electric field is also our research target using up to 1 MHz framing rate of a new detector system. To study non-crystallized bio-molecules and structure change of a cell membrane, fine pixels and a high frame rate of the SOI detector will be effective for a small angle scattering measurement. A high sensitivity for soft X rays of the SOI detector is also very attractive for the studies.
