Postdoctoral position at FREIA
Published: : 2019-10-21
Uppsala University is a comprehensive research-intensive university with a strong international standing. Our mission is to pursue top-quality research and education and to interact constructively with society. Our most important assets are all the individuals whose curiosity and dedication make Uppsala University one of Sweden’s most exciting workplaces. Uppsala University has 44.000 students, 7.100 employees and a turnover of SEK 7 billion.
The research conducted at the Department of Physics and Astronomy encompasses a wide range of physics topics, distributed over ten divisions. The department is located in the Ångström laboratory and employs nearly 400 people, 125 of whom are doctoral students. It offers a broad physics curriculum to undergraduate and graduate students, participation in nationally and internationally leading projects for researchers, and opportunities for partnership with industry and various outreach activities.
Project description: The X-ray free-electron laser (XFEL) is a coherent and tunable light source that offers a spatial resolution at the ångström scale and a temporal resolution at the femto- and subfemtosecond scales. It delivers the highest peak brilliance amongst laboratory X-ray sources today, outperforming even the synchrotron by five to ten orders of magnitude. The X-ray FEL is a revolutionary instrument that enables e.g. characterization of the structure of biomolecules with sub-ångström resolution paving the way to control how they function.
The increasing number of scientific applications and the growing demand for beam time motivate the development of new FEL facilities. However, the X-ray FEL facilities in operation today are generally very long. An ongoing quest in FEL research and development, therefore, is to make the FEL much more compact and affordable for universities.
The prime objective of the project, the successful applicant will work on, is to design a tabletop, high repetition rate FEL using MeV-scale electron bunches and an optical undulator. The successful applicant will study different configurations of the tabletop FEL with the aim of devising a scheme realizable in practice with already existing or coming to the scene accelerator and laser technologies.
The successful applicant will work in a team of dedicated scientists having experience in FEL physics, beam dynamics, superconducting RF engineering and FEL experiments. The FREIA team is currently working on the design of photon beamlines for the national project “Soft X-ray Laser at MAX IV,” and also is in charge of several tasks in the EU project “CompactLight.”
Description of work:
• Critically compare already proposed schemes for compact FELs
• Identify one or two schemes that can realistically be implemented in practice on the timescale of a few years
• Perform conceptual design of all essential components of the compact FEL
• Together with other group members, perform start-to-end simulations of the beam dynamics and FEL process
Requirements: To qualify for an employment as a postdoctor you must have a PhD degree or a foreign degree equivalent to a PhD degree in Physics or related field. The PhD degree must have been obtained no more than three years prior to the application deadline. The three year period can be extended due to circumstances such as sick leave, parental leave, duties in labour unions, etc.
• Deep understanding of wave optics and optical beams in particular
• Solid knowledge of basic laser physics
• Solid knowledge of beam physics
• Experience with multiparticle simulations
• Publications in Physical Review journals or similar level
• The short-listed applicants will be asked to solve a number of test, research-like problems in the field of photon and electron optics.
• Solid knowledge of FEL principles and Compton light sources
• In-depth experience with simulation codes Genesis, Symplex, GPT and Astra
• Experience with electron and photon beam diagnostic
• Previous experience with the design of Compton sources
• High-quality academic writing skills
• Capable to express yourself in a clear, structured and to the point manner
• Capable of preparing clear and concise summaries of ongoing work
• Capable of keeping the work progress well documented, searchable and understandable by other group members
Uppsala University strives to be an inclusive workplace that promotes equal opportunities and attracts qualified candidates who can contribute to the University’s excellence and diversity. We welcome applications from all sections of the community and from people of all backgrounds.
