| 1 | Kei2 ECR离子源C^(4+)、C^(5+)束流的最佳结果(英文)显示文摘Earlier we reported an ion current jump which was observed at a fixed negative biased disc potential in the 6.4GHz ECR ion source at VECC,Kolkata.In a recent experiment with neon ions,we measured the time spectra of the ion current and observed the presence of a burst frequency in the kilohertz range.This frequency shows a correlated jump with the ion current jump described above.Another interesting feature is that the observed burst frequency shows a good linear correlation with the extracted ion current.The higher the ion current,the higher is the burst frequency.This means that current per burst is a constant factor;when there are more number of bursts,the current also increases. | G.S.Taki P.R.Sarma A.G.Drentje T.Nakagawa P.K.Ray R.K.Bhandari | 2007 | Chinese Physics C2007，31，S1： | 0 |
