An In-Situ Calibration System For The Motional Stark Effect Diagnostic On ITER

One of the responsibilities of the United States for the international ITER fusion project is to provide a motional Stark effect system for measuring the internal magnetic field profile. The measurement system will be necessary for plasma control and will enable the study of stability and transport. This project will design a complete and reliable in situ cali¬bration system to ensure the accuracy of data provided by the measurement system. A suite of approaches will be selected to work together to mitigate the difficult ITER condi¬tions. Phase I will involve the design of the calibration system, in order to determine feasibility. In Phase II, hardware and software algorithms for use on ITER will be completed. Commercial Applications and other Benefits as described by the awardee: The ITER project will contribute to the demonstration of an environ¬mentally clean, safe, and abundant energy source. Beyond the magnetic fusion community, the technology should have application to the development of pharmaceuticals and to mili¬tary remote sensing.
