Abstract
Visual information on in-vessel components of ITER, such as divertor and armor tile, is taken by in-vessel viewing and inspection system (IVIS). The IVIS is consist of a visual sensor, a manipulator, a control system and a data processing system. In the IVIS, the sensor and the manipulator are operated under high temperature (about 150degC), high vacuum (about 10{sup -8} Torr) and high radiation (about 10{sup 7} R/hr) conditions. In this report, we studied three different concepts of the IVIS using a fiberscope, a periscope and a industrial television (ITV), respectively. The ITV concept is simple and has high mobility, but radiation, heat and magnetic resistances of ITV are critical issues to apply it to the fusion device, such as ITER. On the other hand, the periscope concept is able to get a large visual field, and the radiation resistance is better than those another concepts. But, this concept has some dead angles by geometrical limitations of the mechanism. Feature of the fiberscope concept is intermediate between those of ITV and periscope ones. From conceptual design of the IVIS, we decided to carry out the irradiation tests of critical elements of fiberscope and periscope. The experimental results become the data
