Fusion has the potential to make a major contribution to the realisation of a sustainable and secure energy supply for the EU a few decades from now, with the international project ITER being the m...

A rotating dual-wire beam profile monitor based upon a National Electrostatics Corporation Model BPM80 beam profile monitor is described. The device can measure beam profiles in two perpendicular directions (horizontal and vertical) in each of two ps

We demonstrate the use of high power diode laser stacks to photodetach fast hydrogen and carbon anions and produce ground term neutral atomic beams. We achieve photodetachment efficiencies of $\sim$7.4\% for H$^-$ at a beam energy of 10\,keV and $\si

We have performed the first energy-resolved measurement of the associative detachment (AD) reaction H−+H→H2−→H2+e−, which is the dominant process forming molecular hydrogen in the early universe. We find excellent agreement between our meas

The decision to build ITER in Europe, at Cadarache, as a joint enterprise of all major partners in international fusion research opens a new era for fusion and is expected to focus a strong world-wide effort towards ITER and ITER-related R&D in fusio

Few-electron ions, which can be produced and studied at rest in electron beam ion traps (EBITs) are very well suited for the study of nuclear size effects and QED in strong fields, but the various contributions are usually entangled. Therefore, combi

Two years after the relocation of the Heidelberg EBIT, several experiments are already in operation. Spectroscopic measurements in the optical region have delivered the most precise reported wavelengths for highly charged ions, in the case of the for
