Spatially resolved ion temperature in a kink-unstable magnetized plasma jet using ion Doppler spectroscopy
1Physical Sciences, Embry-Riddle Aeronautical University, Daytona Beach, Florida 32114, USA.
Abstract:
We present a two-dimensional (2D) ion temperature distribution of a kink-unstable magnetized plasma jet. Using a customized 2D optical fiber array, spatial information was measured in concert with ion temperature measurements derived via ion Doppler spectroscopy to resolve data at locations where the kink-unstable plasma jet deviates from the central axis of the cylindrical system. Substantial ion heating was observed off the central axis when the magnetized jet underwent current-driven kink instability. Details of the 2D ion Doppler spectroscopy system are described.
