Small-scale quasicoherent oscillations of the x-ray emissivity and magnetic field perturbations are observed in the T-10 tokamak during abrupt growth of the m=2, n=1 magnetohydrodynamic modes at the density limit disruption. Analysis indicates a possible link between the small-scale oscillations and nonthermal electron beams induced around the X points of the m=2, n=1 magnetic island during reconnection of magnetic field lines at the disruption instability.
在T-10托卡马克装置中，当m=2、n=1磁流体动力学模式在密度极限破裂时突然增长期间，观测到了X射线发射率的小规模准相干振荡和磁场微扰。分析表明，在破裂不稳定性处磁力线重连期间，小规模振荡与在m=2、n=1磁岛X点周围诱导产生的非热电子束之间可能存在联系。
