在动态空腔的概念中，内爆Z箍缩对于其自身的辐射来说是光学厚度的。辐射可以被捕获在箍缩内，以使箍缩内的辐射温度大于箍缩外的辐射温度。辐射通常通过将外部Z箍缩衬套碰撞到内衬上来产生。碰撞产生强烈的辐射冲击，辐射被外衬套捕获。由于内爆在碰撞后继续，辐射温度可能会继续增加，这是由于内爆所做的持续PdV（压力乘以体积变化）功。原则上，辐射温度可能会增加到外衬烧穿的点，变得光学薄，不再捕获辐射。动态黑腔的一个应用是用俘获的辐射场驱动ICF（惯性约束聚变）弹丸。桑迪亚国家实验室的动态黑腔团队成员使用脉冲功率驱动器Z（20 MA，100 ns）创建了一个新的黑腔。
In the concept of the dynamic hohlraum an imploding Z pinch is optically thick to its own radiation. Radiation may be trapped inside the pinch to give a radiation temperature inside the pinch greater than that outside the pinch. The radiation is typically produced by colliding an outer Z-pinch liner onto an inner liner. The collision generates a strongly radiating shock, and the radiation is trapped by the outer liner. As the implosion continues after the collision, the radiation temperature may continue to increase due to ongoing PdV (pressure times change in volume) work done by the implosion. In principal, the radiation temperature may increase to the point at which the outer liner burns through, becomes optically thin, and no longer traps the radiation. One application of the dynamic hohlraum is to drive an ICF (inertial confinement fusion) pellet with the trapped radiation field. Members of the dynamic hohlraum team at Sandia National Labs have used the pulsed power driver Z (20 MA, 100 ns) to create...
