Description

The double electrostatic ion-beam storage ring is a Swedish national research infrastructure offering beam time to users interested in studying ions of atoms, molecules and clusters. The facility is cryogenic, which results in very long ion-beam storage times and the ions are subject to interaction with a number of different laser sources and, as there are in fact two ion-storage rings in the facility, also to interactions with ions of opposite charges. A main activity is the study of mutual neutralization of interest for astrophysics. In particular studies involving the negative atomic hydrogen ion are important for proper quantitative analyses of stellar spectra to deduce the abundances of heavier elements in the atmospheres of the stars.
