Abstract
The interaction between Z-pinch plasma and foam converter has an important effect on the formation of Z-pinch dynamic hohlraums. A new program has been developed to study related physical processes. Numerical results suggest that the interaction on 7–10 MA drivers is strong enough to create dynamic hohlraums with radiation temperature over 100 eV. Simulations also indicate that a radiating shock would appear due to the collision of Z-pinch plasma and foam converter, in good agreement with the measurements on JULONG-I facility. In this technical note, we present the physical model and simulation results, as well as typical experimental results.
