The ions trapped by beam potential well can cause beam instability in electron storage rings.
在电子储存环中，由于被束流势阱俘获的离子会引起束流不稳定性。
It is suggested that the instability is excited in the low density plasma when the electron beam drift velocities exceed the ion acoustic speed.
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。
The results show that electromagnetic instability can be excited in an ion-beam-plasma system. Ion-electron collisions increase the growth rate of the instability.
结果表明，在离子束-等离子体系统中可以激发维泊耳型电磁不稳定性，离子和电子之间的碰撞将使这类不稳定性的增长率增加。
