Welcome!
Welcome to the website of the DESIREE facility at Stockholm University, a national infrastructure supported by the Swedish Research Council.
DESIREE is a world-unique facility for studies of individual reactions with ions in well-defined quantum states. It is one of only three cryogenic ion-beam storage rings in operation worldwide and the only one where ion-ion interactions, important for e.g. interstellar processes, can be investigated. The facility has two 8.6 m circumference storage rings in a 13-Kelvin chamber where ion beams of atoms, molecules or clusters are stored and merged. This allows for unique studies of quantum-state resolved interactions of individual anion- cation pairs.
A consortium consisting of Stockholm University (SU), the University of Gothenburg (UGOT) and Malmö University (MaU) operate DESIREE as a national infrastructure since January 2018
