Ultrafast Optical Phenomena (OU), X-Ray and Extreme UV Optics (FX)
Years of Experience:
With more than 6,300 employees in research, teaching and administration and its unique profile, TU Dortmund University shapes prospects for the future: The cooperation between engineering and natural sciences as well as social and cultural studies promotes both technological innovations and progress in knowledge and methodology. And it is not only the more than 34,300 students who benefit from that.
Postdoc position (m/f/d) in X-ray laser physics and ultrafast electron spectroscopy w68-20
At the TU Dortmund University, a position for a scientific employee (m/f/d) is available starting at the earliest possible date for a period of up to two years. The postdoc position allows for independent research and provides the opportunity of scientific career development at the Faculty of Physics in cooperation with the European XFEL in Hamburg.
According to public tariff regulations, the salary for the postdoc position is based on tariff group E13 TV-L. For the postdoc position at least a full 100% E13 TV-L salary is available, with previous experience being ac- counted for as appropriate.
For the investigation of the fundamental excitation processes in atoms and molecules it is necessary to observe their dynamics in real time, which happens on temporal scales comparable to a single oscillation pe- riod of the visible light field (2.7 fs at 800 nm). Even shorter “pump” pulses to trigger the atomic and molecular changes require driving wave- lengths in the extreme ultraviolet and X-ray regime. These ultrashort pulses can best be produced at X-ray free-electron lasers (XFELs) like the European XFEL in Hamburg or the LCLS in California, USA.
In the framework of a project funded by the German Bundesministerium für Bildung und Forschung (BMBF) we are developing a novel detection method for a class of ultrafast experiments at XFELs that combine high energy, spatial and temporal resolution with high repetition rates. The envisioned detector consists of multiple, circularly arranged time-of- flight (TOFs) tubes for the simultaneous measurement of electron or ion kinetic energies in arbitrary directions of the detection plane.
YOUR RESEARCH TOPICS: • Supervision of PhD and Master students in the BMBF project and independent scientific leadership in the frame of the project. • Actively planning and taking part in ultrafast electron spectroscopy measurements at XFELs in cooperation with international research groups. A beam time at the European XFEL has been allocated 5 shifts for the next run, preparations are well under way. • Developing and implementing novel research concepts at XFELs for the real-time investigation of excitation dynamics in atoms or in more complex systems, e.g. structural changes in biomolecules. In addition, the positions may involve the preparation and conduction of courses (2 hours/week) as well as the supervision of students.
YOUR PROFILE: • PhD level university degree in physics or a closely related discipline (e.g., electrical engineering) with very good grades. • Experimental experience in electron spectroscopy, ultrashort laser or X-ray-related work work and/or knowledge of detector design and construction. • Familiarity with SIMION and Matlab/Python for simulations and data analysis as well as Inventor or SolidWorks for 3D design of the detector would be helpful. • Experience with writing proposals for third-party-funded projects. • Very good language skills, orally and in writing, in German and/or English.
