Physics researchers awarded competitive grant for upgrading the capabilities of laser spectroscopy
The MSCA-IF is an European Union's internationally competitive funding scheme that aims to promote researcher mobility and help talented researchers to succeed in their career goals.
In his research Ruben de Groote will design, build and use a new experimental apparatus for highly efficient, high-resolution laser spectroscopy on radioactive isotopes produced at the IGISOL laboratory, which is a part of the accelerator laboratory (JYFL-ACCLAB) in the Department of Physics at the Ä¢¹½Ö±²¥. Named RAPTOR, short for ‘Resonance ionization spectroscopy And Purification Traps for Optimized Spectroscopy’, the project will focus in particular on the most challenging atomic systems, whose complexity has so far prevented spectroscopy on unstable atoms.
Achieving this goal requires simultaneous optimization the selectivity of laser ionization schemes for the elements of interest, a refinement of the background rejection of the Collinear Resonance Ionization Spectroscopy method, and maximal exploitation of the trap-based beam purification methods that have been developed at the IGISOL over the past years.
The project will thus combine the existing state-of-the-art capabilities of the laboratory with Ruben de Groote’s experience in high-sensitivity optical spectroscopy of radioactive beams. The RAPTOR project will take place during the coming two years, and should dramatically increase the reach of optical spectroscopy at radioactive ion beam facilities.
Ruben de Groote did his doctoral work at the University of Leuven and graduated in 2017, though most of experimental work happened at the ISOLDE facility in CERN. He has been working at he Department of Physics since October 2017, and has upgraded the capabilities of the existing laser spectroscopy setup.
This work resulted in successful measurements on radioactive silver atoms, which represents the first application of collinear laser spectroscopy at the IGISOL on fast atomic beams, produced via in-flight neutralization of an ionic beam.
