Implementation of laser-driven capacitor coil targets to magnetize an implosion at OMEGA*

We present the design of an experiment using laser-driven capacitor-coil targets (CCTs) at OMEGA. These CCTs, consisting of 2 parallel plates and a wire connector loop, have been demonstrated elsewhere to produce \textgreater 100 T fields over volumes $\gg $mm$^{\mathrm{3}}$. Such fields could be applied to various high energy-density experiments to investigate B field effects. Here, two coils in Helmholtz configuration will be driven by 5 OMEGA beams/coil to produce an estimated seed field of \textasciitilde 50T midway between the coils. To demonstrate their use in an HED target, the CCTs will be placed around a cylindrical implosion of Ar-doped D$_{\mathrm{2}}$ gas driven by 40 OMEGA beams (15 kJ, 1.5ns). The seed B field will be characterized, and Ar K-shell emission will be temporally and spectrally resolved. Our modeling with MHD and radiative calculations predicts the B field can alter the hydrodynamic behavior so much as to be measurable in the Ar spectroscopy. The design and initial results will be shared.
