Results of recent simulations of argon double-shell gas-puff Z-pinch implosions performed at NRL using MACH2-TCRE code in the efficient and inefficient regime are presented. This code was successfully used for modeling argon gas-puff implosions with various load configuration and diagnostic dopant options on Z facility. [1] , [2] Results presented will cover a large set of simulations in the high-current (10 MA to 100 MA) spanning a wide circuit parameter space. Analysis led to the confirmation of I [2] scaling of the efficient K-shell radiation yield previously established by NRL [3] and that it is expected to be valid at high currents. A comparison of the 2D simulation results with the predictions of the updated NRL scaling model incorporating a 0-D snowplow Z-pinch dynamics accounting for the gas-puff load density profile will also be presented.
