Accelerator Physicist (f/m/d) for Operation and Development of the Metrology Light Source

Job Details

The Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) researches solutions for a climate-neutral society. We research complex material systems for an environmentally friendly and sustainable energy supply of the future and provide a large-scale facility for researchers and industry from all over the world with the synchrotron radiation source BESSY II. Furthermore, HZB operates the Metrology Light Source in close cooperation with the Physikalisch-Technischen Bundesanstalt (PTB).

In the Institute for Accelerator Operation, Development and Technology we are responsible for the operation and continuous development of BESSY II and the MLS in order to provide researchers with optimal conditions and new possibilities of use. More than 100 technicians, engineers, and scientists work together in a creative environment to ensure reliable operation and high-quality research for more than 5000 hours per year. In addition, we conduct research for the development of new technologies, methods, and concepts in accelerator science and develop design strategies for the planned successor sources BESSY III and MLS2.
