DESY, with its 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.

European XFEL is the world's brightest operating X-ray laser, with unprecedented opportunity for scientific experiments in the photon sciences. lt is currently heavily oversubscribed, making it important to efficiently and effectively tune this large scale facility for the individual photon users' needs. This requires an improved understanding of the effect of electron beam manipulation on photon beam properties delivered to samples. The goal of the project is to bridge the efforts of the electron beam dynamics and the x-ray propagation efforts by developing a simulation framework for photon pulse properties beyond pulse intensity. The successful candidate's primary location will be within the DESY FEL R&D group, with further working points at the SPB/SFX instrument and the FPH simulation group at EuXFEL.

The position

• Bridge the simulation efforts of electron beam dynamics, FEL generation and x-ray transport
• Develop a simulation framework for complete start-to-end XFEL simulations
• Simulate the effects of various electron parameters on photon beam properties, particularly the propagated wavefront

Requirements

• PhD in FEL physics, x-ray optics or equal qualification
• Additional experience in the respective other field is desirable
• Good command of English, German is a benefit
• Ability to communicate across scientific disciplines
• Experience with relevant simulation codes (Genesis, RWT, 0celot, elegant, ... )
• Experience with setting up cross disciplinary simulation frameworks desirable
