Two high performance pulsed-power accelerators (Z300 and Z800) based on linear-transformer-driver technology have been designed. Much higher yields have been predicted for MagLIF driven with larger peak currents. Here, some agreement with HYDRA and SAMM is obtained, and deuterium-deuterium (DD) neutron yield scaling with current is consistent more » with other existing models and HYDRA simulations. ![]() Following the explanation of the model, three sample problems are presented: first, a Staged Z-pinch implosion on the Zebra driver (1 MA, 100 ns) is modeled and compared with the HYDRA simulation results second, the MagLIF point design is modeled and compared to the original simulation results and results from SAMM and third, we conduct a simple parameter scan and scaling study for a Staged Z-pinch implosion on the LTD-III driver (0.8 MA, 160 ns). The one-dimensional model is a modification of the semi-analytic model for MagLIF (SAMM), that addresses the different set of physics inherent to a Staged Z-pinch implosion: azimuthal magnetic field transport, shock heating of the fuel, separate ion and electron energy equations, and a simplified radiation model that approximates the liner transition from optically thin to optically thick. A semi-analytic model is presented for the gas-puff Staged Z-pinch, a magneto-inertial fusion concept in which an annular gas-puff liner implodes onto a deuterium or deuterium-tritium target. ![]()
