Spatially Resolved, Absolutely Calibrated Soft X-ray Measurements at the Nike Laser Facility
Abstract
The Laser Plasma Branch at the Naval Research Laboratory has an ongoing program to extend and benchmark the atomic physics packages (SCROLL, HULLAC, MIX,..) needed for the radiation-hydrodynamics simulations used to design targets for inertial confinement fusion. Previously, good agreement in absolute spectral intensity was achieved between experimental results and the output of Virtual Spectro, a post-processor for detailed treatment of atomic physics and radiation transport including non-LTE conditions. These initial comparisons were limited to a single line of sight. More recently, absolutely calibrated measurements of soft x-rays (0.5-10 nm) have been made with 1D spatial resolution (dx ∼0.1 mm), spectral resolution (E/dE ∼10-30), and time resolution (t ∼0.3 ns). This poster will present results for a variety of materials and laser conditions with comparison to the results of Virtual Spectro.
