Overview

Tomographic reconstruction of plasma emissivity distribution in fusion reactors, developed from my work I completed during an internship at the Institute of Plasma Physics and Laser Microfusion in Warsaw. Unlike in standard, theoretical tomography settings, fusion plasma reconstruction is severely ill-posed: detectors are stationary, irregularly placed, and often concentrated around specific chamber regions, providing only partial projection data, with some regions being much more data rich.

Implemented reconstruction algorithms from modern scientific literature to handle these geometric constraints and sparse sampling conditions. Built in tools for testing detector layouts in real and synthetic geometries, gaussian and physics based plasma emissivity models, virtual detectors, visualization tools, reconstruction method and it's parameter optimization process.
