Deadline Tuesday, 12. December 2017
The Physikalisch-Technische Bundesanstalt (PTB) is the National Metrology Institute of the Federal Republic of Germany with scientific and technical service tasks. It furthers progress and reliability in metrology for society, the economy and science.
Department 3.2 “Analytics and Thermodynamic State Behavior of Gases” of Division 3 is looking for a
scientist with a doctoral degree
specialized in physics or chemistry in the field of laser spectroscopy
to join us as soon as possible
This position is available on the basis of a 2-year fixed-term contract. If further third-party funds can be raised as expected, a contract extension may be possible. You will be employed at our Braunschweig site.
Depending on your personal qualifications, the remuneration can reach up to remuneration group 14 TVöD Bund.
Scientific implementation of a third-party-funded EMPIR project on optical isotope ratio measurement (OIRS) in gases and gas mixtures
Development, investigation, improvement and application of IR spectroscopic gas analysis procedures for quantifying isotope ratios
Adapting and programming analysis procedures
Metrological characterization of OIRS spectrometers and development of a possible definition of an OIRS standard; design and analysis of test routines
Investigations related to the traceable determination of OIRS using the example of CO2
Investigations related to the traceable determination of molecular spectroscopic parameters (e.g. line width, pressure broadening, pressure shift and temperature dependence of these parameters)
Carrying out comparison measurements in cooperation with project partners
Supervision of a technical work package within the project
Coordination work with international project partners
Experimental R&D for the dynamic wavelength calibration of diode lasers
Integrating scientific research results for the spectrometric quantification of gas mixtures from current or finalized projects into experimental Working Group standards

You have solid background knowledge of
o the metrological aspects of spectroscopy of gases in the NIR and MIR range
o the use of diode lasers, e.g. QCL, ICL, NIRDL
o gathering, processing and interpreting measurement data and IR spectra
o the determination of spectral parameters
o measurement uncertainty analysis (according to GUM)
You have background knowledge in the field of isotope ratio measurements in gases, in particular CO2
You have sound programming knowledge using Python/LabView for laser spectroscopy/metrology
You have knowledge of handling gaseous hazardous substances, gas handling and vacuum technology
You have knowledge of calibrating dynamic wavelengths of tuned diode lasers
You have experience in
o working on scientific tasks within projects (e.g. EMRP/EMPIR)
o cooperating and coordinating tasks in international projects
o project management, ideally in EMRP/EMPIR projects
o raising funds for new projects and reporting on ongoing projects
