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. Equivalent diagnostic response can be generated by integrated radiation-magnetohydrodynamic (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… 

Statistical characterization of experimental magnetized liner inertial fusion stagnation images using deep-learning-based fuel–background segmentation

A convolutional neural network (CNN)-based pipeline is presented to automate much of the image processing workflow and provides a guide for choices made in statistical inference models using stagnation image data and can be applied in the generation of synthetic datasets with realistic choices of noise statistics and background models used for machine learning tasks in MagLIF data analysis.

An overview of magneto-inertial fusion on the Z machine at Sandia National Laboratories

We present an overview of the magneto-inertial fusion (MIF) concept Magnetized Liner Inertial Fusion (MagLIF) pursued at Sandia National Laboratories and review some of the most prominent results

Deep-Learned Generators of Porosity Distributions Produced During Metal Additive Manufacturing

Laser Powder Bed Fusion has become a widely adopted method for metal Additive Manufacturing (AM) due to its ability to mass produce complex parts with increased local control. However, AM produced

It is argued that machine learning models and data-driven methods are in the process of reshaping the exploration of these extreme systems that have hitherto proved far too nonlinear for human researchers.

Strong incompressible three-dimensional magnetohydrodynamic turbulence is investigated by means of high-resolution direct numerical simulations and the spectra and structure of turbulence are obtained in "imbalanced" regions where cross-helicity is nonzero.
