| Research Abstract |
In this study, we carried out the development of in-situ observation experimental apparatus on nano spatiotemporal dynamics to combine the streak camera which had many successful results of the measurements in pico second phenomena on the laser inertial confinement fusion reaction at the target region of the fuel pellets and the various high speed CCD cameras in order to find out a solution of the only remaining issues to improve the temporal resolution and extend the recording time in TEM for three years from FY2009 to FY2011. We installed the newly developed experimental apparatus to our present TEM and investigate the crack initiation point or the multi crack propagation at the interface of the joint under electron irradiation and ion irradiation by recording in nano spatiotemporal resolution where so far it has not been done by us, and revealed the interaction between the multi crack paths which grew in high speed and nano sized defects.
