不稳定性产生的可能机制是由于电子束穿过低密度本底等离子体的漂移速度超过离子声速而激发起来的。
It is suggested that the instability is excited in the low density plasma when the electron beam drift velocities exceed the ion acoustic speed.
该装置由磁场电源、场线圈及电子束漂移管等组成。
The device consists of magnetic field power supply, coils, and drift chamber of electron beam.
对电场漂移电子注入中的电子束物理、电子注入情况下托卡马克等离子体的平衡、电子注手器中的物理问题等进行了分析研究。
In this paper, electron beam physics, equilibrium of plasma in Tokamak under electron injection and physical problems involved in the electron injector were analytically studied.
