Abstract:

ALT-3 Advanced Liner Technology is a collaboration between VNIIEF and LANL that aims to conduct high velocity material experiments and measure shock velocities at pressures near 1 TPa. The DEMG Disk Explosive Magnetic Generator is used to drive a 60MA current that accelerates an aluminum liner to speeds in excess of 20 kms. A simple circuit model is presented that models the DEMG to reasonable accuracy and is then coupled with 1-D magnetohydrodynamic simulations of both the liner and target. 2-D hydrodynamic simulations of the target are also presented along with implications for measurement accuracy and expected results.
