| 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.
