Welcome to the Website of LRC!

LRC is a European project aiming at the study of the wholly unexplored atomic structure of elements beyond nobelium (atomic number Z > 102), which so far represented a big hurdle for common optical spectroscopy techniques. Within the project, a novel and efficient way of laser spectroscopy, termed Laser Resonance Chromatography (LRC), is being developed, which will offer capabilities of both broadband level searches and high-resolution hyperfine spectroscopy of these synthetic elements at minute production quantities. The LRC approach combines the element selectivity and spectral precision of laser spectroscopy with cutting-edge technology of ion-mobility spectrometry mass spectrometry.

Aside of exploring new atomic structures, hyperfine spectroscopy of triply charged thorium and state-selected ion chemistry are some of the many multidisciplinary facets of LRC.

This project is funded by the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme under grant agreement No. 819957. It will run from 2019 to 2024.





Inauguration of the cryogenic drift tube 

October 19, 2022 

Finally, the cryogenic drift tube is assembled, and inauguration experiments are on their way to ensure a smooth operation of the tube under optimal conditions for high temporal resolution. Ti-50 with V-50 and Cr-54 with Fe-54 are the first transition metals we will study before moving on Inauguration of the cryogenic drift tube to the other abundant element isotopes Sc-45 and Lu-175. 


SIMION results for the LRC approach 

September 6, 2022 

SIMION trajectory simulations for Sc+ ions drifting in helium at different reduced electric fields revealed promising resolution in the time domain, which is a key prerequisite for both electronic state chromatography and the LRC approach. More on this can be found here under the following
