Theoretical Analysis of the Frequency Jump in E-fishbone Experiments

It is identified that barely passing electrons are the drive of the e-Gshbones,rather than the barely trapped electrons at low frequency.The frequency jump in e-Bshbone experiments is reproduced and analyzed.It is found that the e-Bshbone frequency increases with the hot electron energy,which is consistent with the experiments.The growth rate of the mode(m = 2,n = 2) is greater than that of the mode(m = 1,n = 1).
