Indirect Drive Cold-Loaded Ignition Target Design

摘要

This document summarizes the Indirect Drive Cold-Loaded (diffusion-filled) Ignition Target design. These targets include a capsule whose strength is insufficient to withstand the room temperature pressure of the DT fuel. These capsules are diffusion filled with DT gas and then cooled to cryogenic temperature. The target must remain at cryogenic temperature until it is shot. Only features that affect the design of the NIF Cryogenic Target System (NCTS) are presented. The design presented is the current thinking and may evolve further.
