Evanko, R G

The details of the design and fabrication of a fiber-optic viewing system are presented. The system was designed for the Thomson scattering profile diagnostic to view discrete plasma points along the line defined by a vertical ruby laser beam inside the vacuum vessel of the DIII-D tokamak. The system is located just outside a vessel port looking through a multiple lens assembly. Fifty-nine fiber-optic bundle locations spaced within a total height of 26.92 cm allow up to 59 discrete plasma points to be observed along a vertical height of 127-152 cm within the vacuum vessel. The essential component of the design is the mechanical mount which holds the viewing end of the fiber bundles. The mount prevents direct handling of the bundles, thus eliminating any damage to the fibers, and allows the bundles to be precisely positioned in any of the 59 locations with relative ease. The use of Computer Aided Design (CAD) and the required precision of the design is discussed. 6 figs., 1 tab.
