Dianion diagnostics in DESIREE: High-sensitivity detection of $C_{n}^{2 -}$ from a sputter ion source

K. C. Chartkunchand, M. H. Stockett, E. K. Anderson +14

A sputter ion source with a solid graphite target has been used to produce dianions with a focus on carbon cluster dianions, $C_{n}^{2 -}$ , with $n = 7 - 24$ . Singly and doubly c…

Rotationally cold OH $^{-}$ ions in the cryogenic electrostatic ion-beam storage ring DESIREE

H. T. Schmidt, G. Eklund, K. C. Chartkunchand +14

We apply near-threshold laser photodetachment to characterize the rotational quantum level distribution of OH $^{-}$ ions stored in the cryogenic ion-beam storage ring, DESIREE, at St…
