Progress towards absolute X-ray spectroscopy on the NIST Electron-Beam Ion Trap: Current status and results

Abstract

Recent observation of Hydrogen-like ions of Vanadium at the NIST Electron-Beam Ion Trap and measurements of Helium-like resonance line are presented. One particular feature of the current series of experiments is the possibility of absolute calibration in a near Doppler-free environment. The current approach to the possible measurement of QED effects in such a system is reviewed. There is great potential for precision measurements in the near future.
