Experiment 2.13 – Collinear Laser Spectroscopy
In this experiment the technique of ‘collinear laser spectroscopy’ is used to measure spectra of singly-charged Barium ions and analyze them. The measurement of hyperfine structure and isotope shifts allow conclusions on nuclear properties of the investigated isotopes.
Due to practical work with a laser, an ion source and an optical detection system you can gain insights in a high precision measurement technique that is for instance used at CERN, but also at numerous other accelerator facilities to do research on exotic and short-living nuclei. Therefore, a multi keV ion beam is produced and overlapped with a laser beam. Part of this experiment a simulation of the beam and the ion optics using the program SIMION. Also you are using an optical detection system to detect resonant fluorescence of the isotopes.
