The Gesellschaft für Schwerionenforschung mbH (GSI, Institute for Heavy Ion Research) in Wixhausen, a suburb of Darmstadt, Germany is a federally funded heavy ion research center. Map of Germany showing Darmstadt Darmstadt is a city in the Bundesland (federal state) of Hessen in Germany. ... ion (disambiguation) An ion is an atom or group of atoms with a net electric charge. ...

The laboratory performs basic and applied research in physics and related natural science disciplines. Main fields of study include plasma physics, atomic physics, nuclear structure research and medical research. This article is about plasma in the sense of an ionized gas. ... Atomic physics (or atom physics) is physics of the electron hull of atoms. ...

The chief tool is the heavy ion accelerator facility consisting of UNILAC, the Universal Linear Accelerator (energy of 2 - 20 MeV per nucleon), SIS 18, the heavy-ion synchrotron (1 - 2 GeV/u) and ESR, the experimental storage ring (0.5 - 1 GeV/u). The UNILAC was commissioned in 1975, the SIS 18 and the ESR were added in 1990 boosting the ion acceleration from 10% of light speed to 90%. A particle accelerator uses electric fields to propel charged particles to great energies. ... An electronvolt (symbol: eV) is the amount of energy gained by a single unbound electron when it falls through an electrostatic potential difference of one volt. ... Nucleon is the common name used in nuclear chemistry to refer to a neutron or a proton, the components of an atoms nucleus. ... Wikipedia does not yet have an article with this exact name. ...

The lab is a member of the Hermann von Helmholtz-Gemeinschaft Deutscher Forschungszentren (HGF), an association of national research centers. The Helmholtz Association (German: Helmholtz-Gesellschaft) is the largest scientific organisation in Germany. ...
