Abstract：
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.
