Your responsibilities

Duties include academic services in the project named above. Research associates may also pursue further academic qualifications outside of their work responsibilities.

We are opening a position at the Center for Free-Electron Laser (CFEL) Science in Hamburg. The project will focus on the implementation of machine-learning-based closed-loop experimentation at the XUV Free-Electron Laser FLASH at DESY in Hamburg in order to enable robust user operation for attosecond science with FELs. The analysis of electron-spectroscopy-based metrology of ultrashort pulses with attosecond resolution will be the basis for an automatized control of the machine optimization. Building a strong collaboration network between photon science, accelerator science and technology is key to this project, hence, project planning and communication will be a substantial part of the tasks. The position is part of the BMFTR project OPTIX, Optimized Processing and Training for Intelligent Experimentation.

This unique opportunity offers the candidate access to cutting-edge technology and a collaborative and diverse environment aimed at pushing the technological, methodological, and scientific frontiers of ultrafast science.

The tasks include:

• literature research
• data analysis of angular-streaking-based attosecond metrology via Python-based algorithms
• correlation of diagnostic data and machine operation of the FEL FLASH for closed-loop-optimization
• communication between computer sciences, photon science, and accelerator science
• conducting experiments, measurements and calculations
• preparation of publications
• participation in conferences
• participation in at least one local graduate school
• analysis and interpretation of scientific data

Your profile

A university degree in a relevant field.

• a completed university degree (diploma/master's) in physics or a related field
• very good experience in the field of X-ray physics and accelerator science and technology, especially regarding free-electron lasers and/or synchrotrons
• very good experience with data analysis, ideally with Python as the programming language
• project management experience
• the candidate ideally has scientific publications as co-author or lead author
• strong organizational and teamwork skills to thrive in a collaborative, interdisciplinary environment
• excellent communication in English is necessary; knowledge of German is a plus
• very good analytical skills
• the candidate must have a thorough and independent working style
• very good experience in preparing scientific papers

• Reliable remuneration based on wage agreements
• Continuing education opportunities
• University pensions
• Attractive location
• Flexible working hours
• Work-life balance opportunities
• Health management, EGYM Wellpass
• Educational leave
• 30 days of vacation per annum
