The first publication of results from an external user beamtime appeared recently in the Journal of Chemical Physics. In their article “Ultraslow radiative cooling of Cn- (n = 3 - 5)”, authors James N. Bull et al. report time-dependent photo-detachment experiments making use of the long storage lifetimes and opportunities for ion-laser interaction at DESIREE. These data are used to determine, for the first time, the infrared radiative cooling rates of isolated cluster ions on ultraslow timescales (seconds to minutes). Read the full paper here.

This is but the first of a parade of user publications expected over the next months.
