In order to fill a fixed-term position in part-time (29.8725 hours/week = 75%) from March 2026, we are looking for a
PhD researcher (m/f/x) for precision spectroscopy of atoms and molecules in plasmas with advanced laser-based diagnostics (infrared frequency comb spectroscopy, THz spectroscopy)
The chair for Experimental Physics V Spectroscopy of Atoms and Molecules by Laser Methods at the Faculty of Physics and Astronomy, Ruhr University Bochum, investigates physicochemical processes in low and atmospheric pressure plasmas. The research is focused on the development and application of advanced laser-based diagnostics from UV to THz to characterize plasmas and their interaction with surfaces, and on highly sensitive laser-based diagnostics using novel lasers in the mid- and far-infrared, including cavity-enhanced spectroscopy, frequency comb spectroscopy, and THz spectroscopy. The research covers the entire spectrum from basic research to applied research and research with industrial partners and includes strong collaborations with plasma modelling. Candidates joining our team will contribute to innovative research at the forefront of plasma physics and chemistry as well as laser spectroscopy.
Your tasks:
- Develop and apply frequency comb spectroscopy and THz spectroscopy setups
- Apply the laser diagnostics to measure atomic and molecular species in low pressure plasmas related to industrial processes
- To carry out detailed studies to elucidate relevant plasma-chemical processes and to identify key species in the plasma
- Determine spectroscopic parameters of plasma-relevant species
- Support the modelling tasks of the plasmas under investigation
- Documentation and presentation of experimental results, including preparation of reports, publications, and contributions to group meetings and at national and international conferences.
- Involvement in national and international collaborations, research as well as industry
- Mentoring of BSc. and MSc. students and teaching obligations
