The above media was taken when we were running with the Rotating Magnetic Field (RMF) Heating System. The video from 10 to 23 seconds shows the plasma rotations are more pronounced and then stabilized later on. The stabilization of plasma is due to the gas puff introduced.
While the PFRC is under upgrade to lower the RF frequency, we have been running the seed plasma, which is PFRC plasma operation without RMF. We also observe rotation in the PFRC seed plasma.
