| Research Abstract |
In 2006, We investigated nano dynamics about irradiation defects and crack propagation of SiC/SiC composite material by a high-speed camera. Furthermore, we summarized results of in-situ TEM observation in the past three years. Accomplishment of our original purpose may be reached up to 70%, but it is thought that I clarified the purpose of this study enough. In addition, development of a pulse electron source of light to be based on a new idea by pulsed laser irradiation to a target in Germany, and to generate the electron which was high strength was done. The new electron microscope which they improved this electronic source and changed for electron gun of a normal electron microscope was developed in U.S.A., and it was reported in an international microscope congress held in Sapporo in September, 2006. Because a study was already made about some topics of materials science, and there were word of mouth and announcement with a poster, positioning of international of this study became clear. In this study, we used a general thermo electron source and a field emission electron source, however, for the American device, a pulsed electron source used. We aimed to record a series of events by a high speed CCD camera, but American team aimed to record an each phenomenon by a pulsed electron source as a strobe image to understand a series of high speed phenomena. However, it was advantage in our method to know the initiation of a certain phenomenon, and future development was expected in the above conference. We explored a new research field in this study and we will continue it in future and should be able to go ahead through a new project as mentioned above. In addition, because new issues were found through this study for the past three years, could reflect for the next project.
