Deceleration-stage Rayleigh-Taylor growth in a background magnetic field studied in cylindrical and Cartesian geometries
文献摘要：
Experiments have identified the Rayleigh-Taylor(RT)instability as one of the greatest obstacles to achieving inertial confinement fusion.Consequently,mitigation strategies to reduce RT growth and fuel-ablator mixing in the hotspot during the deceleration phase of the implosion are of great interest.In this work,the effect of seed magnetic fields on deceleration-phase RT growth are studied in planar and cylindrical geometries under conditions relevant to the National Ignition Facility(NIF)and Omega experiments.The magnetohydrodynamic(MHD)and resistive-MHD capabilities of the FLASH code are used to model imploding cylinders and planar blast-wave-driven targets.Realistic target and laser parameters are presented that suggest the occurrence of morphological differences in late-time RT evolution in the cylindrical NIF case and a measurable difference in spike height of single-mode growth in the planar NIF case.The results of this study indicate the need for target designs to utilize an RT-unstable foam-foam interface in order to achieve sufficient magnetic field amplification to alter RT evolution.Benchmarked FLASH simulations are used to study these magnetic field effects in both resistive and ideal MHD.
