Experimental investigation on X-ray radiation transport along cylindrical cavity target with double diagnostic holes
X射线辐射在双孔柱腔靶中传输实验研究

The cylindrical cavity target with double diagnostic holes was used to investigate the properties of X ray radiation transport along axis of the empty cavity. The simple radiation transport model of `leakage pipe' was put forward and was used to analyze the experimental results of radiation transport in the empty cavity. The analysis showed that the simple model of radiation transport agreed basicaly with the experimental results. The measurements using soft X ray spectrometers (dante) and X ray streaked cameras indicated that at the end of the transportation, the X ray radiation is attenuated, radiation time and relaxation time of the plasma were much longer than those at the entrance.
