Tomographic reconstruction of emission volumes of MagLIF plasmas from orthogonal projection data*

We present our most recent attempts to reconstruct the emission volumes from Magnetized Liner Inertial Fusion (MagLIF) stagnation events using x-ray imaging data from two, orthogonal projection views.  This work is needed to measure the three-dimensional shape of structures previously observed with only single-projection imaging.  Our approach involves the comparison of several reconstruction techniques, including basis function expansions and Expectation-Maximization with a variety of regularization schemes that seek to incorporate physical constraints to improve uniqueness in this highly ill-posed inverse problem.  Ultimately, we expect that an ensemble of solutions from a variety of reconstruction approaches can be used to estimate probability distributions of emission volumes and shape metrics with confidence intervals.
