Öğe Modeling of the L-shell copper X-pinch plasma produced by the compact generator of Ecole polytechnique using pattern recognition(Aip Publishing, 2016) Larour, Jean; Aranchuk, Leonid E.; Danisman, Yusuf; Eleyan, Alaa; Yilmaz, M. FatihPrincipal component analysis is applied and compared with the line ratios of special Ne-like transitions for investigating the electron beam effects on the L-shell Cu synthetic spectra. The database for the principal component extraction is created over a non Local Thermodynamic Equilibrium (non-LTE) collisional radiative L-shell Copper model. The extracted principal components are used as a database for Artificial Neural Network in order to estimate the plasma electron temperature, density, and beam fractions from a representative time-integrated spatially resolved L-shell Cu X-pinch plasma spectrum. The spectrum is produced by the explosion of 25-mu m Cu wires on a compact LC (40 kV, 200 kA, and 200 ns) generator. The modeled plasma electron temperatures are about T-e similar to 150 eV and N-e = 5 x 10(19) cm(-3) in the presence of the fraction of the beams with f similar to 0.05 and a centered energy of similar to 10 keV.
