1. Introduction

We have rearranged BL-14C at the PF experimental hall, where one can get a vertically polarized synchrotron radiation beam, to investigate X-ray phase-contrast imaging, such as X-ray phase-contrast CT using an X-ray interferometer, X-ray diffraction-enhanced imaging (DEI), DEI-CT and X-ray dark field imaging (DFI).

BL-14C1, which was dedicated to X-ray imaging, and BL-14C2, which was dedicated to X-ray diffraction experiments under high pressure and temperature, were rearranged to a large one experimental hutch, BL-14C, for X-ray imaging and other experiments using the white X-rays or the monochromatic X-rays.

A large X-ray interferometer for X-ray phase-contrast CT was installed at the back of BL-14C hutch.
