Precision X-Ray Spectroscopy at the NIST Electron-Beam Ion Trap: Resolution of Major Systematic Error

Some of the most critical tests of the QED Lamb shifts are currently being pursued in the X-ray regime by investigating the core levels of medium Z atoms such as vanadium. The current approach to the measurement of the Lamb shift in such a system is outlined. We present major progress in understanding and reducing the systematic errors within our system. The error budget has been reduced to a level where critical tests of QED can be performed. Recent observations of Lyman α in hydrogenic vanadium at the NISt electron-Beam Ion Trap are presented.
