Disintegrate experiment of X-ray radiation transportation

On the Xingguang-II facility, X-ray transport process in a cavity target wa s simulated in a long cylindrical cavity with slits. High temporally and sp atially resolved microchannel plate (MCP) gated X-ray picosecond frame came ra and soft X-ray steak camera were used to investigate the temporal and sp atial distribution of the soft X-rays emitted from the cavity wall through the slit. X-ray transport velocity, X-ray emission time and the amount of i ntensity decay were obtained. X-ray CCD pinhole transmission grating spectr ometer was used to investigate the spectrum change of the emitted X-rays ve rsus its location. The variation characteristic of the spectrum of X-rays a bsorbed and emitted again and again in transport was obtained. X-ray diodes and Dante spectrometer were used to measure X-ray flux and radiation tempe rature in the slit, the source and the transport end. The typical results i n the experiment were given. About the results, simple and essential analys is and discussions were made.
