During the night of May 18 to 19, the hyperfine transition in lithium-like 208 Bi 80+ ions was observed for the first time at the GSI's experimental storage ring (ESR). A new method

In March, the first user experiment with the new HITRAP deceleration system was carried out at GSI/FAIR. This has now been prominently reported on the GSI website.

Our paper on charge radii of scandium isotopes has been published in Phys. Rev. Letters today. By measuring the isotopes 47-49 Sc we could establish the charge radii across the f 7/2 shell.

Imke Lopp has completed her Master Thesis with the presentation „First Atomic Beam Laser Spectroscopy at COALA and Demonstration of State-Selective Charge Exchange in Strontium“. Congratulations!

Our measurement of hydrogen-like Bi-208 has been published in Nature Physics . It is the first time that laser spectroscopy was performed at an accelerator-produced isotope in a storage ring.

Jonas Ködel has completed his Master Thesis with the presentation „Software-Guided FPGA Timing for Precision Ion Trapping“. Congratulations!

Finn Köhler has completed his Master Thesis with the presentation „Development and Commissioning of an RFQ Cooler-Buncher for Laser Spectroscopy“.

A paper from MIRACLS which studies the impact of the drift length on the performance of MR-ToF devices has been published in Nucl. Instr. Meth. A. .

Daniela Tandara's poster “Analysis of the Composition of the Beam from a Penning Ion Source at COALA” won a poster prize at the DPG's Spring Meeting of the Section Hadrons and Nuclei in Cologne.

The Python package “qspec” developed by Patrick Müller in our research group provides many functions for simulating and fitting atomic spectra and the interaction processes between ions/atoms and photons.
