Study of Soft X-Ray Spectrum from a Small Gas-Puff Z-Pinch Device

Summary form only given. A Ross filter difference spectrometer was developed to study the soft X-ray radiation emitted from gas-puff Z-pinch plasma. It is composed of PIN detector arrays in combination with front Ross filters. Filter materials and thickness was selected by the desired X-ray spectral energy cuts. To measure softer X-ray energy spectrum, we mainly used the L absorption edges of elements (K absorption edges was used only for light elements). Two selected filter-PIN combinations formed a difference pair to measure a channel X-ray spectral intensity. Our spectrometer, in the spectral range from 0.2 keV~1.5 keV, could provide us with five channels spectral results covering the energy interval of interest without gaps. By means of the spectrometer, the time resolved X-ray signals and the energy spectrum of X-ray from a small gas-puff Z-pinch device were obtained, and the errors of measured spectrum intensity were analyzed and estimated
