| Research Abstract |
It is significant to upgrade traditional X-ray diffraction technique by giving real-space imaging capability in addition to conventional 'average' diffraction patterns. Furthermore if the imaging becomes very quick, the technique will be a fairly sophisticated tool to see the materials being synthesized. Then one could say that"Seeing is Creating" rather than "Seeing is Believing". In the present study, a new X-ray imaging technique developed at National Institute for Materials Science (Japanese patent, No.3049313, No. 3663439, No. 3834652 and others) has been employed for looking at changes of samples during cooling, heating and some other chemical reactions. So far, in the field of X-ray diffraction imaging, only static imaging had been known. As trying movie was for the first time, we needed a very strong X-rays.The experiments were carried out with a multi-pole wiggler source at BL16A1, Photon Factory, KEK, Tsukuba, Japan. We did experiments 6 times; November and December in 2005, and February (twice), April and May in 2006. In the first year, the instrument has been completed, and it has become possible to obtain real-space X-ray diffraction images, of which pixels correspond to the sample positions. The pixel numbers of X-ray image is 1000 x 1000,and the spatial resolution is 10 30micron. The interval of capturing image is 0.01 10 secdepending on the experiments. A cooling/heating device has been also installed. In the second year realistic observation has been achieved ; crystallization from solution, icing and frosting, solidification of liquid metals etc., which can take place between-15 and 40℃.
