Tender Details

Opportunity:
Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its x-ray compensation in hohlraums with spherical shine shields.
Background:
For ICF implosions that are x-ray driven, the hohlraum that drives the implosions develop a pole-hot x-ray field late in time due to plasma ingress. There are a number of approaches to mitigating this late-time drive (e.g., changing laser cone-fraction in time, altering cross-beam-energy transfer, altering hohlraum-capsule geometry) but these tactics have been pushed to their limits. In order to maintain control of ICF target implosion symmetry, which will enable higher fusion yields, a new solution is needed in target design.
Description:
This LLNL invention details a unique approach that involves the incorporation of a new geometry of spherical shine shields, which occupy a small volume above the north and south pole of the capsule early in time during the ICF implosion. Upon exposure to late-time hohlraum x-rays, they explode into a cloud of high atomic number (Z) material (e.g. gold or depleted uranium). This cloud of high-Z plasma will hinder the effects of the pole-hot drive, thus improved implosion symmetry is obtained.
Advantages/Benefits:
Simple modification to the hohlraum/target geometry that does not require pulse shape modifications
A 70% increase in yield when spherical shine shields are utilized compared to current best in class solution that is reaching its maximum achievable yield potential
Potential Applications:
Novel high yielding target concepts for Inertial Fusion Energy (IFE)
Development Status:
Current stage of technology development: TRL ☒ 0-2 ☐ 3-5 ☐ 5-9
