Theoretical Development of the Modeling of EUV and X-Ray Radiation from Plasmas with Low-Z Elements and Application to Pulsed Power Experiments

Summary form only given. Non-LTE kinetic models of low-Z elements are developed and their applications to Z-pinch and MITL experiments are discussed. In particular, theoretical EUV and X-ray spectra of C, O, and Na ions are presented and calculated for different plasma parameters, which account for different experiments. EUV spectra covered the spectral region of interest from 50 to 600 Aring that corresponds to the operating region of the available EUV spectrometer. The best candidates for plasma diagnostics among the calculated line transitions from C, O, and Na ions are proposed which are the most sensitive to changing of plasma parameters in this particular spectral region. Some of the EUV spectra together with X-ray spectra recently collected in Al with 5% NaF coating wire array experiments are analyzed. These experiments were conducted on the 1 MA generator at UNR. Application of these models and synthetic spectra to the existing and future MITL experiments on the 20 MA Z accelerator at SNL is considered and discussed
