Quantification of MagLIF morphology using the Mallat Scattering Transformation

Understand

The morphology of the stagnated plasma resulting from Magnetized Liner Inertial Fusion (MagLIF) is measured by imaging the self-emission x-rays coming from the multi-keV plasma, and the evolution of the imploding liner is measured by radiographs.

• Equivalent diagnostic response can be derived from integrated rad-MHD simulations from programs such as Hydra and Gorgon.
• There have been only limited quantitative ways to compare the image morphology, that is the texture, of simulations and experiments.
• We have developed a metric of image morphology based on the Mallat Scattering Transformation (MST), a transformation that has proved to be effective at distinguishing textures, sounds, and written characters.
