PhD position in SRF cavity control for gravitational wave searches

Role Overview
In the MAGO project, we will develop the detection and control of RF fields of a superconducting cavity to be used to search for high-frequency gravitational waves. This interdisciplinary project is carried out together in our particle physics group and the group which is responsible for the controls, feedback regulations and synchronization of the particle accelerators at DESY.

Responsibilities
- Further development of high-precision RF field control of superconducting radio frequency (SRF) cavities used in gravitational wave search experiments.
- Further development of carrier suppression interferometer (CSI)-based techniques and their integration to the low-level RF (LLRF) system.
- Development, production, test and operation of state-of-the-art RF measurement devices, to be installed at our cavity test stands.
- Development of algorithms to assess and automate the calibration of the RF control and measurement system.
- Performing measurement studies using the developed system on SRF cavities with a very high quality-factor.

Requirements and Qualifications
- MSc. degree in Physics, Electrical Engineering or Computer Science or equivalent qualification.
- Experience in RF design and measurements is beneficial.
- Familiar with the theory of SRF cavities, interest in particle physics experiments.
- Computer science skills e.g. Linux, Python, Matlab (competence in firmware and software is a plus).
- Strong motivation and pragmatism towards problem solving, teamwork as well as highly proficient English skills.

What They Offer
- A unique working environment on an international research campus.
- Respectful cooperation and focus on employee well-being.
- Gender equality is an important aspect.
- Support for work-life balance including flexible working hours, variable part-time, job-sharing models and participation in mobile work (up to 50%).
- Family-friendly and collegial atmosphere.
- Established health management and occupational pension provision.
- Secure workplace as a public funded employer.
- Comprehensive training and development opportunities to facilitate individual career growth.
- Remuneration according to the regulations of the TV-AVH.
- Financial supplement for a German job ticket (Deutschland-Ticket) at both locations.
