Recent advances in cryogenic layering include the development of a self-contained and self-filling hohlraum, application of phase contrast x-ray measurements for ice layer characterization, and an ice layer achieved with beta-layering which meets the NIF specification for surface roughness at 1.5 K below the triple point. In addition, recent results on target integration in a hohlraum show effective layer control using heaters on the hohlraum.
