X-pinch experiments using conichrome alloy wires were implemented on 1MA COBRA facility at Cornell University. X-ray spectral and imaging data were collected. In particular, the spatially-resolved, time-integrated x-ray line K-shell and L-shell spectra of Cr, Co, and Ni ions from these alloy X-pinches were recorded in one pulse using a mica crystal spectrometer. Non-LTE kinetic models were applied to model these spectra. The results of this modeling are presented and the interpretation of K-shell and L-shell Cr, Co, and Ni as well as L-shell Mo spectra from conichrome alloy X-pinches are discussed.
