  Application of new detectors using Silicon-On-Insulator (SOI) technology has
been started in the Photon Factory, KEK. This project has two purposes. The
first purpose is to develop a pulse-counting-type X-ray detector which can be
used in synchrotron soft X-ray experiments. The second one is to apply the SOI
area detector developed by RIKEN, SOPHIAS, to X-ray diffraction and small-angle
scattering experiments in Photon Factory. In this paper, we introduce the
current status of our project.
