Testing quantum electrodynamics in extreme fields with the heaviest two-electron ion Fig. 1: The drawing of one of the two Bragg crystal spectrometers mounted at the gas-jet target of the ESR for measurement [...] spectrometers were constructed and mounted at the gas-jet interaction chamber of the ESR (see Fig. 1). A new calibration method and other improvements resulted in a 37-parts-per-million transition energy

The existing [...] whose floor lies as deep as 17 meters under the earth’s surface. The SIS100 has a circumference of 1,100 meters and can accelerate the ions of all the natural elements in the periodic table to speeds as
