Description

Synchrotron radiation X-ray imaging is a powerful tool for observing internal structure of objects. It has been used for medical science, material science, and earth science researches, and also applied in industrial cracking and welding examination. Beamline BL1.2W is a newly constructed facility at the Siam Photon Laboratory dedicated to the X-ray imaging and the synchrotron radiation X-ray tomographic microscopy (SRXTM) technique. The beamline utilizes polychromatic beam of synchrotron radiation in X-ray region, which is produced from multipole wiggler with a magnetic field of 2.4 T and 5 magnetic periods. The X-ray beam is collimated by a toroidal mirror located at 8.9 m from the source and delivered to a sample at 34.12 m downstream. The beam size at sample position is 10 x 4 mm2 (H x V). An X-ray image is generated based on the differences in attenuation coefficient of the material composition. The X-rays that pass through a sample will be converted to visible lights by scintillation and magnified by a microscopic lens system for submicroscopic detailed visualization. Recent commissioning phase of BL1.2W showed that X-ray images could be obtained with a spatial resolution beyond 5 µm.
Currently, BL1.2W is under commissioning phase for the X-ray tomographic microscopy (SRXTM) and will be opened for academic and industrial users by the end of 2016. This technique will allow for a non-destructive characterization of internal structure via 3D reconstruction and mathematic sectioning of a sample, which will be useful for precious samples.
