Summary form only given. A general overview of Mo planar wire array implosions (single, double, and triple) from the past three years on the 1 MA, 100 ns UNR Zebra generator is presented. Mo planar wire arrays on Zebra have radiated high peak powers and yields (up to 1 TW and 24 kJ) as well as produced high-temperature L-shell plasmas (up to 1.4 keV), indicating the importance in connection with inertial confinement fusion. In addition, Mo planar wire arrays combined with Al are presented. Implosion dynamics in different load geometries is analyzed with a wire-ablation dynamics model (WADM). Bright spot dynamics is considered with RMHD simulations. Overall trends of various implosion results, such as energy output, as functions of various parameters, such as load type and linear mass, is discussed. Plasma parameters of electron density and temperature derived from non-LTE models of Mo and Al are also presented and discussed. The advantage of using Mo wires for future study of wire arrays is demonstrated.
