U.S. ITER Diagnostics, X-ray Imaging Spectrometer

In the ITER program the U.S. will provide a high resolution core imaging x-ray spectrometer that must operate with high fidelity when subjected to extraordinarily intense neutron and gamma ray radiation generated by ITER. The proposed Phase I effort will assess the ability of the x-ray detector arrays to perform and survive in this ITER radiation environment. This information will guide the development in Phase II of radiation tolerant detector arrays for the ITER x-ray spectroscopic diagnostics. Commercial Applications and other benefits: The primary application is instrumentation for experimental fusion energy research ongoing in the United States, Europe, and Asia, with the international ITER program as the prime example.
