Angular filter refractometry analysis using simulated annealing [An improved method for characterizing plasma density profiles using angular filter refractometry]
Here, a new method of analysis for angular filter refractometry images was developed to characterize laserproduced, longscalelength plasmas using an annealing algorithm to iterative converge upon a solution. Angular filter refractometry (AFR) is a novel technique used to characterize the density pro files of laserproduced, longscalelength plasmas. A synthetic AFR image is constructed by a userdefined density profile described by eight parameters, and the algorithm systematically alters the parameters until the comparison is optimized. The optimization and statistical uncertainty calculation is based on a minimization of the $$\chi$$2 test statistic. The algorithm was successfully applied to experimental data of plasma expanding from a flat, laserirradiated target, resulting in average uncertainty in the density profile of 510% in the region of interest.
