Phase contrast enhanced x-ray imaging of ICF capsules
Abstract
We experimentally demonstrate phase-contrast enhanced x-ray imaging of deuterium-tritium (D-T) fuel layers inside of a copper-doped beryllium ablator using a point-projection x-ray microscope. Solid D-T layers with a RMS roughness of 2 μm have been made inside of a Be capsule. Computational modeling demonstrates that a rough surface can be accurately characterized using phase-contrast enhanced x-ray imaging. This characterization method is applicable to other ICF capsule and target designs, particularly with materials of similar or low opacities.
