Numerical Simulation of the Interaction Between Z-Pinch Plasma and Foam Converter Using Code MULTI (#18353)

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...

Summary: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.
