The dynamic hohlraum (DH) is an approach to Inertial Confinement Fusion, and its X-ray radiation can be widely used in high energy density physics. The shock wave in dynamic hohlraum is important because it heats the foam to high radiation temperatures. Here, we proposed a simple model to describe the shock wave in the dynamic hohlraum. Based on the Rocket ablation model, this simple shock model connects the wire-array implosion phase and the shock formation phase. We also use the experimental result of dynamic hohlraum with a heavy foam mass acquired on primary test stand to verify this model. This simple shock model helps researchers to estimate when and where the collision happens so that researchers could understand the physics in DH more clearly. Published by AIP Publishing.
