Design of Instrumentation & Control and Optical Table Instruments for the Divertor Flow Monitor Diagnostic at ITER

This master's thesis describes the process of the design and instrument selection for a future optical table, part of a plasma flow monitor diagnostic system at the international thermonuclear experimental reactor, ITER. The diagnostic system is designed to detect the presence of edge localized mode, low to high confinement mode transition of plasma, and plasma flow velocity in the divertor region of the reactor. It accomplishes this by performing spectroscopic measurements of visible light radiating from specific elements inside the reactor. The selection of these elements are based on previous experiments performed at the joint european torus (JET). The light is transported via a system of lenses and mirrors to the optical table where it is directed through a series of optical instruments. Finally, the light is subsequently captured by cameras who live stream the images via the internal network to a control center. To aid the development of the schematic and instrument selection, optical design simulations of the light transmission path were performed to ensure that the design could provide sufficient level of light itensity to the cameras at a defined trajectory. The selection of instruments, light transmission results, computer aided design- and simulation models of the optical table are presented in this report. While the selected components satisfied most criteria specified by its predefined system requirements, the project also serves as a foundation for future improvements of the optical table, including changes to any of the instruments, schematics, and optical design simulations.
