Characterisation of coherent rotating modes in a magnetised plasma column using a mono-sensor tomography diagnostic

摘要

In this paper we report on an original tomographic diagnostic using a single sensor on a magnetized plasma column. The experimental setup and the numerical inversion method used to interpret the data are presented. The core plasma evolution during the rotation of coherent modes is characterized with this tomography diagnostic. The experimental observations show that the mode shape is constant during the plasma rotation. The results are also compared to two-dimensional probe measurements.
