Summary form only given. Spatially-resolved and spatially-integrated X-ray spectral data and time-integrated and time-resolved pinhole X-ray images accumulated from Cu wire arrays and X-pinch experiments on the Zebra generator have been analyzed. In particular, Cu wire arrays were investigated with different number of wires and load sizes, and Cu X-pinches implemented with two and four wires with several diameters have been considered. Cu wire arrays were composed from both pure Cu wires and Cu alloys with 4% of Ni. Non-LTE kinetic models of Cu and Ni have been applied to account for the L-shell and K-shell radiation from the Cu and Ni ions. The advantage of using Cu alloys with a small percentage of Ni for diagnostics of Cu wire arrays will be illustrated. The resulting plasma parameters from modeling the Cu wire arrays and X-pinches will be discussed
