Transition frequencies, isotope shifts, and hyperfine structure in transitions of Ti ions

Tim Ratajczyk, Kristian König, Philipp Bollinger +4

We have measured transition frequencies, isotope shifts and hyperfine structure splittings in the $3 d^{2}\left({ }^{3\!}F\right) 4 s\,{ }^{4} F_J\rightarrow 3 d^{2}\left({ }^{3\!}…

Towards a New and Compact Gas-Dynamic Cooler- Buncher for the FAIR Laspec and MATS Experiments

Victor Varentsov

In this article, we propose a new gas-dynamic ion beam cooler-buncher for the FAIR Laspec and MATS experiments. This very compact and having a simple design gas-dynamic cooler-bunc…

Proposal for applying the novel gas-dynamic ion-beam extraction and bunching technique to the cryogenic stopping cells at FAIR

Victor Varentsov

To enhance the quality of pulsed cold ion beams extracted from the two cryogenic stopping cells at FAIR (i.e., the one currently used in the FRS and the one under development for t…

An RF-only ion-funnel for extraction from high-pressure gases

Thomas Brunner, Daniel Fudenberg, Victor Varentsov +74

An RF ion-funnel technique has been developed to extract ions from a high-pressure (10 bar) noble-gas environment into vacuum ( mbar). Detailed simulations have been perfo…
