Job description:


DESY is one of the world’s leading research centres for photon science, particle and astroparticle physics as well as accelerator physics. More than 2400 employees work at our two locations Hamburg and Zeuthen in science, technology and administration.

The Photo lnjector Test facility (PITZ) in Zeuthen (near Berlin) develops high brightness electron sources for Free-Electron Lasers (FELs) like FLASH and European XFEL. Generation of electron bunches with extremely low emittance and very high phase space density is one of the important goals of the R&D program at PITZ. The emittance of state of the art photoinjector electron sources is dominated by the cathode emittance, so understanding and improvement of photocathode and photoemission dynamics are of great importance for further increasing the electron source brightness.

The position

Work in one of the world-leading groups for photo injector developments with physicists and engineers Perform numerical modeling of photoemission processes near the cathode surface on both sides (both in the material and in vacuum) for semiconductor cathodes like Cs2Te and CsK2SbDesign and analyze experiments and compare with simulations Participation in shift operation for accelerator R&D at PITZ and/or XFEL


PhD in physics, strong background in semiconductor surface physics, especially for photoemission modeling is of advantageKnowledge/skills in experimental characterization of photocathodes and photoemissionFamiliar with monte carlo simulation and high level scripting languages (Python/Matlab), good programming skillsGood command of English, knowledge of German is of advantageExcellent teamwork spirit in an international working environment

Salary and benefits are commensurate with those of public service organisations in Germany. Classification is based upon qualifications and assigned duties. Handicapped persons will be given preference to other equally qualified applicants. DESY operates flexible work schemes. DESY is an equal opportunity, affirmative action employer and encourages applications from women. Vacant positions at DESY are in general open to part-time-work. During each application procedure DESY will assess whether the post can be filled with part-time employees.
