Achieving high pressure shock Hugoniot measurements in cylindrical geometry using a high-explosive pulsed power drive
Abstract Not Provided
DEMG simulations
AL T-3 is an experiment being designed in collaboration between Russian VNIIEF scientists and LANL that aims to conduct high velocity material experiments to measure shock velocities and pressures near 1 TPa. The DEMG (Disck Explosive Magnetic Generator) is used to drive > 60MA currents to accelerate an aluminum liner to speeds in excess of 20 km/s. A simple model of the DEMG is presented along with its ability to replicate results generated by Buyko et. al.
ALT-3 target design and simulations
ALT-3 is an experiment being designed in collaboration between Russian VNIIEF scientists and LANL that aims to conduct high velocity material experiments to measure shock velocities and pressures near 1 TPa. The DEMG (Disck Explosive Magnetic Generator) is used to drive> 60MA currents to accelerate an aluminum liner to speeds in excess of 20 km/s. 1-D and 2-D simulations of the aluminum target are presented with information on the free surface velocity profile, the state of the target, and the shock velocity in the target. 2-D simulations are presented showing the different targets available as well as a scenario with a perturbed liner impacter.
