Status of QED tests in heavy highly charged ions — •Paul Indelicato — Laboratoire Kastler Brossel, École Normale Supérieure, Université Pierre et Marie Curie, 75005 Paris, France

In the last few years the use of heavy-ion storage rings and low-energy ion sources has lead to a steady increase of the availability of high-precision measurements of transition energies in few-electron highly charged ions. At the same time, accurate calculations of QED and relativistic effects in one, two, and three-electron systems have become available, which include all one- and two-loop radiative corrections, evaluated to all orders in the fine structure constant, as well as exact second-order electron-electron interaction corrections. In this talk I will present recent results obtained at the ESR storage ring in Darmstadt, and with low-energy ion sources in Heidelberg and Paris. Elements ranging from medium-Z to uranium have been studied. Comparison with theory and experiment will be discussed. Perspectives connected with future facilities and progress in hydrogen and helium will be outlined.
