“…Our experiments were carried out at the Omega Laser Facility 45 , which is a 351-nm, 60-beam Nd:glass laser with up to 500 J of energy per beam. Targets consisted of an 11-µm-thick Mo foil (GoodFellow Corp., 99.9% purity) attached with thin (~1 µm) epoxy layers between a 25-µm-thick polyimide (CH) layer and a 120-µm-thick LiF window (Fig.…”

Molybdenum (Mo) is a body-centered-cubic (BCC) transition metal that has widespread technological applications. While the BCC transition elements are used as test cases for understanding the behavior of metals under extreme conditions, the melting curves and phase transitions of these elements have been the subject of stark disagreements in recent years. Here we use X-ray diffraction to examine the phase stability and melting behavior of Mo under shock loading to 450 GPa. The BCC phase of Mo remains stable along the Hugoniot until 380 GPa. Our results do not support previous claims of a shallow melting curve for molybdenum.

“…The Defect Induced Mix Experiment (DIME) shots on the Omega laser [9] were designed to validate our mix models so that we can understand mix in convergent geometries and ultimately feature-driven mix. In this paper, we describe Omega experiments involving spherical capsules without defects that are a first step in our experimental plan.…”

“…The development was first carried out based on a set of indirect drive implosions at the Laboratory for Laser Energetics' OMEGA laser [5]. In order to compare the datadriven analysis to a theoretical framework, two independent mix models, Youngs' phenomenological model [6] and the Haan saturation model [7], were previously implemented in conjunction with a series of clean hydrodynamic simulations which modeled the experiments in question [4].…”

The mixing between fuel and shell materials in Inertial Confinement Fusion (ICF) implosion cores is a current topic of interest. The goal of this work was to design direct-drive ICF experiments which have varying levels of mix, and subsequently to extract information on mixing directly from the experimental data using spectroscopic techniques. The experimental design was accomplished using hydrodynamic simulations in conjunction with Haan's saturation model, which was used to predict the mix levels of candidate experimental configurations. These theoretical predictions were then compared to the mixing information which was extracted from the experimental data, and it was found that Haan's mix model performed well in predicting trends in the width of the mix layer. With these results, we have contributed to an assessment of the range of validity and predictive capability of the Haan saturation model, as well as increased our confidence in the methods used to extract mixing information from experimental data.
