离子源引出束流的波动在电磁同位素分离器中是较为关键的问题。早期Nezlin研究发现,束流的波动对电磁同位素分离器的分离能力有直接的影响。在磁场中,由于磁场对电子的约束非常明显,束空间电荷的中和比较缓慢。在束流波动明显时,容易造成离子束欠中和,降低离子束在聚焦面的聚焦性能,影响同位素的丰度。在180°电磁同位素分离器中,离子源内置于 The pulsation of the ion source extraction beam is a more critical issue in the electromagnetic isotope separator. The early Nezlin study found that the fluctuations in the beam have a direct effect on the separation capability of the electromagnetic isotope separator. In the magnetic field, due to the magnetic field of the electron constraints is very obvious, the beam space charge neutralization more slowly. When the flow fluctuates obviously, it is easy to cause the ion beam to be under neutralized, which will reduce the focusing performance of the ion beam on the focusing plane and affect the abundance of the isotope. In the 180 ° electromagnetic isotope separator, the ion source is built in
