| 英文摘要 | a multiframe, gated pinhole system capable of quantitative acquisition for pulsed soft x rays is described and tested. the system based on a gated microchannel plate (mcp) is employed to observe the evolution of z-pinch plasma in a plasma focus facility with a time resolution of similar to 220 ps. the quantitative relationship between x-ray source intensity and the recorded images has been investigated. to make a quantitative measurement, the phosphor screen current was measured to calculate the total electrons output from the mcp, which is proportional to both the incident x-ray intensity and the intensity of the recorded images. furthermore, by taking into account the pinhole geometry, mcp gain and system spectral response, a quantitative calibration of the x-ray images has been established. we have employed the system to observe the plasma evolution in a plasma focus facility. an order of similar to 10(16) photons/(s mm(2) mrad(2)) soft x-ray emission within 6-14 angstrom was observed in a neon puffed experiment with time resolved four successive frames.
