Abstract:

The details of the implosion compression hot spot was detected by the multi-channel Kirkpatrick- Baez microscope with high spatial resolution of about 3μm. The X-ray self emission of the hot spot is measured along the two orthogonal directions of the equator and the polar, and the spatial distribution of the two dimensional X-ray intensity is obtained. The X-ray image data show that the equatorial asymmetry component of the hot spot is larger than that of the polar about 8%. The P2 component in polar is 2μm larger than that in the equatorial region. This results show that the polar compressing of the hot spot is stronger than that in the equatorial region. It indicates that the radiation driven in polar region is stronger than that in the equatorial region, which causes the shape of the hot spot to be oblate at the implosion stagnation.
