The US Role in ITER Diagnostics

There are ~40 specialized diagnostics planned to measure the many plasma parameters needed for research on ITER. The US played a key role in this planning effort and is gearing up to play a major role in providing these systems. This paper gives a brief status of diagnostic planning for ITER and summarizes the challenges posed by the ITER environment. It then describes the 16% of the ITER diagnostic hardware provisionally allocated for development in the US, and explains key elements of that development
