The turbulence spectroscopy group develops and operates 2D Beam Emission Spectroscopy (BES) systems and other turbulence spectroscopy diagnostics at fusion facilities around the world
Postdoc opportunity at DIII-D (Feb. 1, 2021) – Our turbulence diagnostic group is seeking applicants for a postdoc position to carry out a research program in edge-ML and real-time inference in connection with the 2D BES system at DIII-D in San Diego, CA. Applications received by February 26, 2021 will receive full consideration. Please see the full postdoc position description here.
Graduate research opportunities at NSTX-U – Our turbulence diagnostic group is recruiting graduate students to begin graduate studies in Fall 2021 in the Department of Engineering Physics at UW. The students will pursue thesis research in connection with the 2D BES system at NSTX-U. Please contact George McKee and David Smith for more information.
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.
Feasibility study for future BES measurements at W7-X at IPP in Greifswald, Germany
Our group supports several graduate students who routinely travel to host facilities to carry out graduate thesis research.
