Deadline: 05.07.2021


DESY, with its more than 2700 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.

The Photo lnjector Test Facility at DESY in Zeuthen (PITZ, near Berlin) is one of the world leading institutions to develop new concepts for high brightness electron sources fullfilling the needs of modern Free-Electron Lasers (FELs). As part of the Helmholtz association, those concepts are integrated into large scale FEL facilities, such as FLASH at DESY and the European XFEL in Hamburg.
The research roadmap at PITZ is focused on further improvements of pulsed photo injectors, developments towards high brightness CW electron sources, electron beam driven high power THz generation, and the exploration of short pulse, high intensity cancer radiation therapy. The improvement of the photocathode laser system is essential to enhance the performance and reliability of current and future photo injector systems.

About the role:

  • Work in an interdisciplinary team of physicists and engineers to enhance the performance and reliability of current and future photo injectors
  • Participate in the development and production of a new photocathode laser for PITZ; this work will be carried out in close collaboration with the FS-LA laser group at DESY in Hamburg
  • lnstall, commission, and operate the laser at the PITZ facility in Zeuthen, do further developments for specific needs
  • Participate in shift operation of PITZ for accelerator R&D
