DESY, with more than 2900 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.
DESY expands its research on novel laser-plasma accelerators (LPAs) for future applications in health, photon science, and particle physics. At the core of these activities is the development of plasma-based injector for the synchrotron light source PETRA IV. In this context, we are searching for a highly-motivated scientist to develop new plasma targets (including targets supporting high average power), tailored target chambers and their support systems, and integrate said plasma targets and chambers in the plasma accelerator beamline.
With the PETRA IV project, DESY is launching one of the most ambitious and innovative large-scale research projects worldwide. PETRA IV, the most brilliant synchrotron radiation source of the next generation, will be the ultimate 4D X-ray microscope, setting new standards in precision and performance. To implement the project, we are looking for motivated employees who want to get involved in a complex project with international appeal. More information about PETRA IV: PETRA IV
- Contribute to the development of the PETRA IV plasma injector
- Develop and operate novel plasma targets for LPAs, also with a focus on high average power operation
- Develop, implement and operate corresponding chambers
- Integrate target chambers into the LPA beamline, and adopt them to the requirements of laser and electron beam transport
- Develop concepts to efficiently and actively cool LPA targets, with a focus on long-term stable operation
- In this context, perform complex multi-physics simulations, including heat transport, computational fluid dynamics and molecular flow
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.
