Application of beryllium deuteride as a material for laser X-ray target shells

The target ignition under the conditions corresponding to the National Ignition Facility (USA) was investigated. Beryllium deuteride BeD2 with a small admixture of copper was considered as the target shell material. The shell parameters and the profile of a target-irradiating X-ray pulse were selected, which ensure the DT-fuel ignition. The total fusion energy release of the target was shown to amount to ~19 MJ for the optimal choice of its parameters, which corresponds approximately to the fusion energy release of the target with a beryllium shell.
