Abstract

The achievement of fusion ignition at the National Ignition Facility opens new opportunities for foundational studies in opacity, radiation transport, and high-flux astrophysics in regimes previously unattainable. We have succeeded in the critical enabling step of demonstrating ignition in a hohlraum modified with diagnostic windows that burn through prior to ignition, granting experimental access to the brightest radiation source in the laboratory. This Letter reports the results of a deuterium-tritium-layered capsule implosion that achieved 2.4±0.09 MJ neutron yield in a hohlraum with windows designed to allow the escape of radiation energy from the capsule without significant loss of implosion symmetry, thus establishing a validated platform for next-generation radiation-driven experiments.

点火驱动辐射通过THOR热腔的演示。

国家点火装置的聚变点火为不透明、辐射输运和高通量天体物理学的基础研究提供了新的机会。我们已经成功地迈出了关键的一步，即在一个装有诊断窗口的热腔中演示点火，该诊断窗口在点火前会燃烧，从而允许在实验室中使用最亮的辐射源进行实验。本文报道了一个氘-氚层状胶囊内爆实验的结果，该实验在一个有窗户的腔室内实现了2.4±0.09 MJ的中子产率，该腔的设计使辐射能从胶囊中逸出，而不会明显失去内爆对称性，从而为下一代辐射驱动实验建立了一个经过验证的平台。
