Observation of multiple beta-induced Alfvén eigenmodes driven by runaway electrons in EAST Ohmic discharge

Multiple Beta-induced Alfvén eigenmodes (BAEs) excited by runaway electrons (REs) have been observed in low-density Ohmic discharges in the EAST tokamak. The toroidal mode number is mainly n = −1 and they rotate in the electron diamagnetic drift direction. These modes in the low frequency range from...
