Spectroscopic modeling of radiation from Cu and Mo X-pinches produced on the UNR 1 MA Zebra generator
2006
X-pinches are a source for studying radiative properties of plasmas of very small sizes, high densities and temperatures applicable to high-energy density plasmas such as dense Z-pinches. Recently, spatially resolved and spatially integrated X-ray spectral data have been accumulated during Mo and Cu X-pinch experiments on the Zebra generator. During these experiments configurations, other then the 2-wire X-pinches, such as 4-wire X-pinches and asymmetric X-pinches have been spectroscopically studied and computationally analyzed. We present here modeling of the K-shell and L-shell radiation from Cu X-pinches with two and four wires and the comparison with experimental spectra. L-shell radiation from symmetric and asymmetric Mo X-pinches with two wires and X-pinches with four wires have also been analyzed and compared. Dependence of the plasma spatial structure, temperature, and density on wire materials and load configurations are discussed.
