DESY

DESY's free electron laser (FEL) FLASH offers unique opportunities for multidisciplinary research in the extreme ultraviolet (XUV) and soft X-ray range. The very intense, femtosecond pulses in combination with synchronized optical laser systems and strong THz pulses allow exploring ultrafast time-scales using pump-probe techniques. We have an immediate opening for a scientist position at the newly established pulse length-preserving monochromator beamline FL23 in combination with the high-resolution monochromator beamlines at FLASH1. The research activity will focus on dynamical studies of the electronic structure, correlation effects, and magnetic properties in e.g. quantum materials using time-resolved soft X-ray spectroscopy techniques. Together with the FLASH monochromator team, the successful candidate will be in charge of further developing the beamlines, participating in the commissioning with seeded FEL beam, supporting the user operation at the monochromator beamlines, as well as conducting own FEL experiments.

About your role:

• Characterisation and operation of the ultrafast FL23 beamline for time-resolved X-ray spectroscopy experiments
• Performing FEL based spectroscopy experiments using different techniques like X-ray absorption, X-ray photoemission, RIXS etc. to study ultrafast dynamics on solid samples in the XUV & soft X-ray range
• High quality support for international user groups during experiment campaigns at the monochromator beamlines with active participation in the experiments
• Contribution to the in-house research activities at FLASH

About you:

• PhD in experimental physics, chemistry, materials science or a related field
• Experience in photon science using FELs or synchrotron radiation sources
• Experience with soft X-ray and optical spectroscopy, optical absorption spectroscopy or Raman spectroscopy
• Knowledge of pump-probe techniques using femtosecond lasers is considered as an asset
• Team player with excellent communication skills in English to pursue highly collaborative research programs and work in large international collaborations

Look forward to a unique working environment on our international research campus. Respectful cooperation and the well-being of our DESY employees are particularly important to us. Gender equality is an important aspect for us. To support work life balance we offer flexible working hours, variable part-time, job-sharing models and participation in mobile work (up to 50%). You will benefit from our family-friendly and collegial atmosphere, our established health management and occupational pension provision. As a public funded employer, we offer you a secure workplace and facilitate your individual career with our comprehensive training and development opportunities. Remuneration is according to the regulations of the TV-AVH. DESY offers its employees a financial supplement for a German job ticket (Deutschland-Ticket) at both locations.

We look forward to receiving your application via our application portal:
