A 2d hybrid code is designed, and in order to test it, the beaminstabilities in plasma using this code is studied.
设计了一个二维混合模拟程序，并用其计算了等离子体物理中的束流不稳定性。

It was observed in machine study that, Landau damping caused by the octupole field can suppress the beam collective instabilities.
在机器研究过程中观察到束流集体不稳定性可以被八极磁场产生的朗道阻尼很好地抑制。

Beam breakup (BBU) instabilities resulted from interaction of beam and cavity will deteriorate beam quality. Transverse impedances reflect the degree of such interaction.
