The ZaP Flow Z-Pinch forms a stable Z-pinch with an embedded axial flow. The two-dimensional plasma structure is important to measure to make accurate comparisons to flow stabilization theory. The plasma structure reveals the axial wavelengths of unstable modes as well as radial displacements. Two photo-diode arrays placed in an azimuthal plane around the experiment measure line integrated emissivity of the plasma. Deconvolving these using tomographic techniques determines the two-dimensional structure of the plasma emissivity. Measurements from an interferometer and magnetic probes determine the spatial correlation between plasma emissivity, plasma density, and plasma currents. These data advance the understanding of the Z-pinch plasmas and ultimately flow-stabilization theory.
