Position: Doctoral candidate specializing in physics
Institution: Physikalisch-Technische Bundesanstalt
Location: Braunschweig, Niedersachsen, Germany
Duties: The thorium-229 nucleus has a state which is at an unusually low excitation energy of approximately 8 eV. This allows laser spectroscopy methods to be applied to a nuclear transition for the first time and opens up the possibility for a novel, extremely precise optical “nuclear clock” as well as for testing fundamentals of physics as regards the strong interactions. Your work in Working Group 4.44 will focus on: Participating in developing and setting up a VUV laser system at a wavelength of 150 nm and with a beam line towards an ion trap; VUV laser spectroscopy on trapped ions, resonant laser excitation, and laser spectroscopy of the thorium-229 nucleus; Investigating the laser excitation of Th-229 in doped crystals produced by our cooperation partner at the TU Wien, Austria
Requirements: You have successfully completed your university studies in physics (German Diplom or Master’s degree); Experimental experience with part of the fields of laser optics, laser spectroscopy, trapped ions, and ultra-high vacuum systems would be an advantage; You are able to perform target-oriented scientific work; You are a team player with excellent communication skills
