摘要
在KT-5C托卡马克等离子体中进行了磁场涨落的测量,获得了磁场涨落的频谱和径向分布,实验结果表明,磁场涨落的幅度随着等离子体半径的增加而减少,对于不同q值的放电条件下都是如此.实验中还观察到如果在限制器上施加正偏压的话,能够相当有效地抑制磁场涨落的幅度.
The magnetic fluctuation measurements are conducted in the KT-5C tokamak.The frequency spectra and the radial profiles of the poloidal magnetic field fluctuations fordifferent values of q show that the amplitudes of fluctuations decrease as the plasma radiusincrease. Besides,the remarkable influence of limiter biasing on the magnetic field fluctuation are observed.
