Conceptual Design of Low Pressure, 300 degree K Fill System for Ignition Target Capsules with Micron Size Fill Tubes
A conceptual design for a low pressure, room temperature, fill system suitable for ignition target capsules is described. The fill system relies on the use of a 5-10 micron diameter fill tube connecting directly the target capsule to a DT fuel reservoir. The design uses a small reservoir to store the DT fuel at room temperature within the target assembly. A model of the design is developed and used to calculate reservoir size, layer thickness control, and control sensitivity. A procedure to fill the target in-situ after cooling the assembly to cryogenic temperatures using temperature control of the reservoir is also described. The effects of He3 generation and fuel contamination are also discussed.
