The DESIREE facility will be open for external users from within Sweden, from Europe or from anywhere in the world. Research at the DESIREE-facility may for example include:
- Studies of mutual neutralisation reactions in collisions between positive and negative ions at tunable center-of-mass energies ranging from a few meV and up to the keV region. Experiments with light (atomic) and heavy (molecular/cluster) ions are possible. Complex ions may be internally cooled.
- Action spectroscopy – photoabsorption spectroscopy with internally cooled, stored, ions.
- Studies of unimolecular decay, stabilities and lifetimes of multiply charged negative and positive ions. As the rings may be operated at low temperatures it is possible to study stabilities of, and reactions with, negative ions, anions, which are dissociated by blackbody radiation at normal room temperatures.
- Studies of biomolecular ions, their stabilities and sensitivities to various heating and ionization processes and their bond-forming processes.
Immediate applications of the research may include:
- Fundamental atomic, molecular, and cluster physics – the option to study ion-ion collision is so far world unique
- Astrophysics. DESIREE offers unique possibilities to study reactions and photospectroscopy in conditions like those in many regions in space.
- Radiation damage on the molecular level
- Atmospheric physics and chemistry. Ion reactions like those in the atmospheres of Earth and other planets or moons (e.g. Titan) may be studied. The temperature of DESIREE may be regulated from 10 K and up to room temperature and above.
The local research environment around DESIREE and at Stockholm University is formed around experimental and theoretical work on for examples atomic, molecular, and cluster physics, chemical physics, astrophysics and –chemistry, accelerator physics, and advanced detector technologies and developments.
