Title:	Simulations of NDCX-II Targets for Warm Dense Matter and Heavy Ion Fusion Physics*
Abstract:	The Neutralized Drift Compression Experiment II (NDCX II) is an induction accelerator now being constructed at Lawrence Berkeley National Laboratory and scheduled for project completion in March 2012. The baseline design calls for a 1.5 - 3 MeV, ~30 A Li+ ion beam, delivered in a bunch with sub ns pulse duration, and transverse dimension less than ~ 1 mm. The purpose of NDCX II is to carry out experimental studies of material in the warm dense matter regime (WDM), and ion beam and hydrodynamic coupling experiments relevant to heavy ion based inertial fusion energy (HIF). In preparation for NDCX-II, we have carried out hydrodynamic simulations of ion-beam-heated, porous and solid, metallic and non-metallic, targets. We have calculated the temperature and velocity at the critical surface, to estimate the predicted optical intensity and laser interferometer inferred velocity time profiles based on the simulated density, temperature, and velocity of the target. We have shown the sensitivity of these observables on two equations of state. Pulse formats include single pulses of fixed ion energy, and pulses with varied energy to create shocks and investigate ion-coupling efficiency. Simulated target geometries include spherical and cylindrical bubbles (to create enhanced regions of higher pressure and temperature), in addition to planar solid and planar foam targets. *Work performed under the auspices of the U.S. Department of Energy under contract DE-AC52-07NA27344 at LLNL, and University of California contract DE-AC02-05CH11231 at LBNL.
