22.10.2026 Postdoctoral Researcher SRF Cavity Control for Axion and Gravitational Wave Searches at DESY Hamburg DESY invites applications for a postdoctoral position in the SHOGWAVE and the SONAR projects, which uses superconducting radio-frequency (SRF) cavities to search for high-frequency gravitational waves. The postdoc will join the LLRF development team and help set up and further develop the project’s dedicated LLRF system, including carrier suppression interferometer (CSI) techniques and their integration into it. The position combines independent research with student supervision on cryogenic low-noise RF components such as oscillators, multipliers, mixers, filters, switches, amplifiers, attenuators and phase shifters. The work spans electronic design, prototype development, system characterization and concept evaluation. Read…

22.10.2026 PhD position in SRF cavity control for gravitational wave searches at DESY Hamburg DESY invites applications for a PhD position in the SHOGWAVE/SONAR project, which uses superconducting radio-frequency (SRF) cavities to search for high-frequency gravitational waves. The candidate will join the low-level RF (LLRF) development team. The work covers further development of high-precision RF field control and of carrier suppression interferometer (CSI) techniques, including their integration into the LLRF system. It also includes developing, building and operating RF measurement devices for the cavity test stands, designing algorithms to automate the calibration of the control and measurement system, and carrying out measurement studies on very-high-Q SRF cavities.
