• As part of your job, you will be responsible for the following tasks in particular:
• Construction and characterization of a Penning trap based on permanent magnets
• Characterization of the vacuum conditions in the cryogenic trap chamber
• Development and testing of cryogenic vacuum valves
• Conception and design of a miniaturized transport trap for antiprotons

• Completed university degree in physics or a completed bachelor's degree with a master's degree expected to be completed by the start of employment
• Very good specialist knowledge in physics and the ability to independently design new technical developments
• Sound practical knowledge in the field of experimental physics and safe handling of laboratory instruments
• Ability to work in a team, independent and proactive way of working
• Very good communication skills, especially in English
• Willingness and ability to acquire in-depth expertise in the field of precision measurements with Penning traps during the training period
• You meet the requirements for admission as a doctoral candidate at the Faculty of Mathematics and Natural Sciences of the Heinrich Heine University Düsseldorf according to the doctoral regulations

We are offering a doctoral position (TV-L 13, 65%) limited to three years on the DFG third-party funded project "Miniaturization of a Transportable Antiproton Trap," and the opportunity to contribute to an attractive research project in the field of antimatter physics. The project is linked to Prof. Ulmer's chair and, within the framework of the BASE collaboration at CERN, is working toward improved comparisons of the fundamental properties of protons and antiprotons. This provides access to an attractive scientific environment and laboratory infrastructure for the development of cryogenic trap experiments. The project will be carried out on-site at HHU Düsseldorf, with optional contributions to antiproton beam time at CERN.

The academic collaboration will take place within the framework of the above-mentioned project, although an independent doctoral project can be pursued. This is therefore a qualification position within the meaning of the German Act on Temporary Employment in Science (Wissenschaftszeitvertragsgesetz – WissZeitVG), which is intended to promote the academic qualification of the employee.

The employment is initially limited to a period of 3 years.

Our research group is one of the leading groups in the field of antimatter physics, working in particular on high-precision measurements with antiprotons in Penning traps and leading the BASE collaboration at CERN. In particular, we have developed methods to measure the magnetic moment of the antiproton through spin quantum jumps of a single trapped particle and have performed the most precise measurements of the proton and antiproton magnetic moments. Details about our group and our research can be found here.
