Spectroscopic and MHD modeling of magnetized cylindrical implosions using a laser-produced seed B-field*

We present a comprehensive simulation study of magnetized cylindrical implosions at OMEGA using laser-driven capacitor-coil targets to produce a seed, pre-compressed B field. Ar-doped, D2-filled cylindrical targets will be symmetrically imploded using a 15 kJ, 1.5 ns laser drive. The plasma dynamics are numerically investigated in 2-D with the MHD code GORGON, which predicts a B-field exceeding 10 kT over the entire compressed core and significantly higher temperatures compared to the unmagnetized case. Synthetic X-ray emission spectra computed with the NLTE atomic kinetics code ABAKO and detailed Stark-Zeeman broadening codes (MERL, PPP-B, DinMol) show distinctive spectral features for a magnetized implosion and the case without seed B-field. These results suggest the use of Argon K-shell spectroscopy to extract plasma conditions throughout the implosion and bring information about changes in the hydrodynamic behaviour due to the impact of the B-field.
