Postdoctoral Researcher — SRF Cavity Control for Axion and Gravitational Wave Searches

Develop ultra-low-noise control and readout for superconducting radiofrequency cavities in searches for axions and high-frequency gravitational waves. Work on the MAGO prototype, low-level RF systems and carrier-suppression interferometry; design, build and characterise cryogenic RF components and supervise students. This two-year appointment is in Hamburg, with full-time/part-time options and remuneration up to group 13 under DESY’s collective pay arrangements.

PhD in electrical engineering or equivalent specialist knowledge/experience, with several years designing, building and modelling low-noise MHz–GHz RF electronics. Analogue/digital electronics, modern RF measurements, CAD tools such as Altium and RF modelling are expected. SRF-cavity theory and interest in particle-physics experiments are advantageous. Submit the stated application package and arrange three reference letters through the employer’s separate reference tool.
