脉冲电子束离子存贮的研究

The study on the ion storage by using pulsed electron beams

在离子存贮的研究中,我们采用脉冲电子束去轰击射频阱中的中性原子或分子而产生离子,这样可清楚地将离子的产生过程和信号测量过程分开,同时,利用信号平均和多道分析的手段提高信噪比。

In the study of ion storage,pulsed electron beams were used to impect neutral atoms or molecules in radio frequency trap to produce ions,so the process of producing ions was separated from that of measurement,and the methods of signal average and multi-channal analyzer were used to raise the signal-to-noise ratio.
