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℃.

对传统的X射线衍射技术进行升级改造，使其在传统的“平均”衍射图样的基础上具有真实空间成像的能力，具有重要意义。此外，如果成像变得非常快，该技术将是一个相当复杂的工具，可以看到正在合成的材料。所以，我们可以说：“看是创造”，而不是“看是相信”。在本研究中，一种新的X射线成像技术开发的国家材料科学研究所（日本专利，第3049313号，第3663439号，第3834652号和其他）已被用于观察样品在冷却，加热和其他一些化学反应过程中的变化。迄今为止，在X射线衍射成像领域，人们只知道静态成像。由于电影是第一次尝试，我们需要一个非常强的X射线。实验是在日本筑波KEK光子工厂的BL 16 A1多极摆动器源上进行的。我们做了6次实验; 2005年11月和12月，2006年2月（两次），4月和5月。在第一年，该仪器已经完成，并已成为可能获得真实空间的X射线衍射图像，其像素对应于样品的位置。X射线图像的像素数为1000 × 1000，空间分辨率为10 ~ 30 μ m。根据实验结果，采集图像的时间间隔为0.01 ± 10秒。还安装了冷却/加热装置。在第二年，实现了现实的观察;从溶液中结晶，结冰和结霜，液态金属凝固等，这可以在-15至40℃之间发生。
