Overview of A New 3D MMI Ray-Tracing Tool*

Inertial confinement fusion is one method used to obtain controlled thermonuclear burn through either direct or indirect ablation of a millimeter-scale capsule with the use of high-power lasers. Although there have been large strides made in understanding the physics involved in order to create reliable physics models and codes, simulations and experiments still show discrepancies. A factor in this mismatch is the asymmetry of the implosions that occur experimentally. The multi-monochromatic X-ray imager (MMI) is an instrument which gives spatially, spectrally, and temporally resolved arrays of narrow-band x-ray images which can be used to extract temperature, density, and mixing spatial profiles. A new 3D ray-tracing tool has been developed that allows for the designing and characterizing of MMI [D. T. Cliche and R. C. Mancini, Appl. Opt. \textbf{58}, 17 (2019)]. The tool also allows for the production of synthetic MMI data with a higher degree of fidelity previously obtained.
