Research Engineer in Measurement Systems

Are you interested in working with measurement systems in an advanced laboratory environment where we develop and test superconducting components for the particle accelerators of the future? We are an international team working to provide the best possible support, both to local research activities and to international research infrastructures that rely on superconducting accelerator technology.

We are now looking for a research engineer who wants to contribute to this exciting and challenging work.

About the Position

The position is located at the FREIA laboratory, operated by the FREIA department under the Department of Physics and Astronomy. Physics and Astronomy is one of the largest departments at the university, with about 400 employees, conducting research in many different areas. At FREIA, we conduct research and development in instrumentation and particle accelerators in collaboration with international research networks and large-scale research institutes such as CERN in Switzerland and ESS in Sweden.

At the FREIA laboratory, we design, build, and test advanced equipment that will be used for research at the forefront of science. For example, the laboratory houses two large cryostats where superconducting acceleration cavities or magnets are cooled to extremely low temperatures using liquid nitrogen and helium, while being supplied with strong fields or currents under careful monitoring, in order to evaluate their performance.

This complex infrastructure relies on advanced measurement systems for radio frequency measurements and magnetic field measurements, which require continuous maintenance as well as regular adjustments and expansions to meet new needs and tasks. The applicant will thus have the opportunity to play a key role in both the use and improvement of these systems.

Responsibilities

• Use and development of low-level radio frequency systems (LLRF)
• Software development for LLRF systems
• Operation and development of radio frequency measurement systems for low and high power.
• Plan, execute, and document qualification tests of superconducting cavities and acceleration modules.
• Contribute to the overall operation and development of the FREIA laboratory.
• Participate in the work of other research projects at the FREIA laboratory, such as superconducting magnets.

We work in international collaborations, so travel may be required. Work during inconvenient hours may also occur.

Qualifications

The applicant should have a master's degree in physics, electronics, or equivalent. You should be driven and results-oriented, as well as open and flexible to new tasks. You should take responsibility for and be able to organize work with multiple tasks simultaneously.

The following competencies and abilities are required for the position:

• Very good oral and written skills in English.
• Ability to work independently and in a team consisting of various skills and competencies.
• Ability to read and understand technical documentation.
• Ability to communicate well at both technical and general levels.
• Good ability to organize and document work.
• Ability to report work orally and in writing in English.

To be successful in the work, knowledge and experience in the following areas are also required:

• Matlab or equivalent
• Programming in C/C++, Python, etc.
• Software development
• Applied mathematics, e.g., data analysis
• Labview
• Applied superconductivity

Desirable/meritorious

Knowledge and experience in the following are meritorious for the position:

• Signal theory
• Control engineering
• Low-level FPGA programming (HDL)
• Labview FPGA programming
• LLRF systems
