June 14, 2021 – The turbulence spectroscopy group in the Department of Engineering Physics seeks applicants for a postdoc position to develop and deploy a 2D Beam Emission Spectroscopy (BES) diagnostic system at the W7-X stellarator to advance the scientific basis for fusion energy. The full position description and application instructions are available at https://fusionlab.ep.wisc.edu/turbulence/w7-x-bes-postdoc/.
The turbulence spectroscopy group develops and operates 2D Beam Emission Spectroscopy (BES) systems and other turbulence spectroscopy diagnostics at fusion facilities around the world
2D BES systems are versatile diagnostic tools to investigate plasma turbulence and instabilities on the ion-gryoscale. BES systems observe the Doppler-shifted Balmer-alpha emission from neutral heating beams, and the cross-beam configuration measures localized density fluctuation with high time resolution. BES measurements have advanced the scientific understanding of plasma turbulence, the LH transition, zonal flows, and the turbulent Reynolds stress. George McKee, David Smith, and Zheng Yan carry out the BES research program at the following fusion facilities.
