PhD researcher (m/f/x) for ro-vibrational distribution measurement in transient discharges by precision frequency comb spectroscopy
The Ruhr-Universität Bochum is one of Germany's leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. 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 terahertz (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 absorption spectroscopy. The research covers the entire spectrum from basic research to applied research and research with industrial partners and includes strong collaborations on plasma modelling. Candidates joining our team will contribute to innovative research at the forefront of plasma physics and chemistry as well as laser spectroscopy.
We are looking for a highly motivated doctoral candidate for the project “Ro-vibrational distribution measurement in transient discharges by precision frequency comb spectroscopy” funded by the German Research Foundation (DFG) in the framework of the Collaborative Research Centre (CRC) 1316 “Transient Atmospheric Plasmas – from Plasmas to Liquids to Solids” focusing on plasma catalysis (). The energy distributions of molecules generated by the plasma provide insight into the generation of reactive species and reaction mechanisms relevant for efficient conversion. This project utilizes FCS, which uniquely provides broadband coverage, high resolution and sensitivity, to determine a detailed picture of ro-vibrational distributions of molecules in plasma processes, including CO and CO2 for CO2 conversion into renewable fuels or chemicals, and on topics as diverse as the decomposition of volatile organic compounds and biocatalysis. The results will be compared with measurements using coherent anti-Stokes Raman scattering (CARS) and quantum cascade laser absorption spectroscopy (QCLAS).

RUB sees itself as a university with an international presence. The campus languages are German and English. German language courses are offered by the University Language Center (ZFA) in the field of German as a Foreign Language (DaF).
For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas.
