Plasma diagnostic-related activities at Shanghai EBIT

In this report, plasma diagnostic-related activities at the newly developed Shanghai electron-beam ion trap (EBIT) are reviewed. The density of the electron beam was measured by employing a slit imaging system, and the ion densities of bare and H-like Kr were studied using radiative recombination emissions of n= 1 processes. A first intrashell (KLL) dielectronic recombination resonant spectrum of xenon is also shown and discussed. Finally, ion density oscillations from possibly different mechanisms than those seen earlier at the Berlin EBIT are observed and discussed.
