Brief description The first critical tests of many-body and correlated Quantum Electro-Dynamics (QED) in medium-Z atomic systems. Major difficulties are being encountered in the computation of high-order and correlated terms of Quantum Electro-Dynamical effects in atoms. We will make the first measurements for medium-Z atoms critically sensitive to two-electron QED, and the first tests of QED in this region accurate to 1%. This accuracy will allow new insight into two-electron systems, theoretical approaches, and recent observed discrepancies between QED theory and experiment. This proposal follows recent successful experimental work using new capabilities of Electron-Beam Ion Traps (EBITs). Our recent publications have proven that this novel approach can yield new insight into the interaction of light with matter.
