Abstract
This paper shows the present status of experimental apparatus and the results from synchrotron radiation (SR) X-ray topography at Photon Factory in KEK. The real time observation by using X-ray TV can be achieved at SR X-ray topography, so the main purpose of these experiments is to get information on dynamic behavior ; for example melting and growth processes, phase transitions and etc. The typical experiments for such subjects are described. Recently, monochromatic X-ray topography was tested by using wiggler beam line, and it was confirmed that the real time observation could be also achieved and that the sample heating from the radiation of X-ray beam was negligibly small at monochromatic X-ray topography.
