Spectroscopy |
|
Goal / Teaching Aim | Plasma spectroscopy: learn emission processes and try to obtain plasma information out of the measured spectrum |
Equipment | Plasma source with possibility of applying magnetic field, high-resolution spectrometer, 2D-CCD camera |
Experiment | Measure spectra from several plasmas, observe line splitting due to Zeemann effect and determine magnetic field |
Fusion Relevance | Line radiation from plasma is a way to radiate the power away and a common diagnostic to obtain plasma parameters like impurity content, magnetic field temperature and rotation |
