NIF target fabrication

The NIF requires complex and precise targets to perform its mission. The most complicated of these are the indirect-drive cryogenic ignition targets. At the center of these targets is a ~2 mm diameter capsule that is filled with hydrogen fuel-in most cases, a solid layer of a 50:50 equimolar mixture of deuterium and tritium in equilibrium with its vapor at 1.3-1.5 Kelvin below the triple point at shot time. The capsule and the fuel are concentric and centered inside a high-Z hohlraum. An example of an ignition target is displayed in Figure 1.
