X-ray micro imaging and tomography at SPring-8

Orateur : Kentaro UESUGI (Spring 8)

Many kinds of X-ray imaging experiments are done at three beamlines (BLs) in SPring-8. They are BL20XU, BL20B2 and BL47XU. Those BLs have unique characteristic as follows. BL20XU : Medium length BL (245m), hybrid undulator light source, high coherence at end station. BL20B2 : Medium length BL (215m), bending magnet light source, large beam size (300mm x 20mm). BL47XU : normal length BL (53m), SPring-8 standard undulator light source, high flux density (1.0E+14 photon/s/mm2). X-ray micro-tomography, 2D live-imaging (metal alloy, mice) and test study of X-ray optics are done at BL20XU. 3D-XRD measurements are also available. In BL20B2, in-vivo measurements of small animals, phase contrast tomography (grating interferometer system) and calibration and adjustment of X-ray telescope (ASTRO-H by JAXA) are going with the large beam. BL47XU is used for nano-imaging with FZP optics. The nano-imaging system has been used for analyze the small particles recovered from asteroid ITOKAWA [1]. All of the developed system is opened for SPring-8 users. At the seminar the outline of those beamlines and some experimental results of users will be shown. [1] A.
