By compressing a small sphere of deuterium-tritium using very powerful lasers in a process called inertial confinement fusion, experimentalists have produced a net gain fusion reaction for the first time. However, the gain is significantly under-predicted using the most advanced numerical tools, primarily due to the growth of fluid instabilities. Understanding and controlling the levels of instability growth is critical to achieving more efficient fusion. This international collaboration proposes to employ computations and experiments to deliver a fundamental understanding of mixing layers in implosions and explosions, to provide validation of reduced order models and contribute towards the development of the ultimate energy source.

通过在惯性约束聚变过程中使用非常强大的激光压缩一个小的氘氚球，实验学家首次产生了净增益聚变反应。然而，使用最先进的数值工具，主要是由于流体不稳定性的增长，增益显着低于预测。了解和控制不稳定性增长的水平对于实现更有效的聚变至关重要。这项国际合作计划采用计算和实验来提供对内爆和爆炸中混合层的基本理解，提供降阶模型的验证，并为最终能源的开发做出贡献。
