Experimental validation of modeling and simulation for fusion systems is often limited by the available facilities and their unique diagnostic measurement capabilities. At the same time, each magnetic confinement device
has a range of engineering parameters that must be configured to execute experiments including heating power, plasma density, and magnetic field strength. Often it is not straightforward to design an experiment in which the outcome is unambiguous and sufficiently quantifiable to validate or falsify modeling and simulation predictions. ORNL has decades of experience in partnering to perform domestic and international fusion energy experiments, including linear plasma devices, tokamaks, and spherical tori and stellarators. ORNL maintains staff members at many of these facilities. In addition, our team includes recognized experts in fusion measurement science, including active and passive plasma spectroscopy, laser-plasma diagnostics and diagnostics to characterize power exhaust, and particle control such neutral pressure measurements, infrared surface thermography, and bolometry. Our team can help plan a strategy for experimental validation and can examine any needs for new measurement or analysis tools that may require specially tailoring.
