Fig. 5: Spectrally integrated amplitude of magnetic fluctuations measured in Bz showing the shift from predominantly n = 1 to n = 2 type fluctuations corresponding to the evolution in dominant fast ion orbit type during the field reversal period as the plasma radius grows.
From: Generation of field-reversed configurations via neutral beam injection
Amplitudes of both of these fluctuations are small due to electrode biasing stabilization. Data from 25 neutral beam injection generated field-reversed configuration shots across the Norm experimental campaign used to generate this plot. Dark traces are the medians of all shots in the series.
