Wire tomography in the H-1NF heliac for investigation of fine structure of magnetic islands

Kumar, Santhosh T. A.; Blackwell, Boyd D.; Harris, Jeffrey H.


Electron beam wire tomography in the H-1NF heliac enables high resolution mapping of vacuum flux surfaces with minimal disruption of the plasma operations schedule. Recent experimental results have proven this technique to be a highly accurate and high resolution method for mapping vacuum magnetic islands. Islands of width as small as delta approximately 8 mm have been measured, providing estimates of the internal rotational transform of the island. Point-to-point comparison of the mapping...[Show more]
