Abstract

Microwave diagnostics have potential to provide localized measurement of the electron density (ne) and temperature (Te) with good spatial (a few cm) and temporal (<; 1 ms) resolutions through all phases of ITER. Development of these diagnostics is a major challenge because of severe environment, strict engineering requirements, safety issues and the need for high reliability in the measurements. Most of the diagnostic components that are placed in a high radiation environment are expected to operate in this environment for a period at least until the next planned maintenance session. This paper will cover the conceptual design of microwave diagnostics and their interface with vacuum vessel and port plugs.
