Fully automated cryogen-free modular physics measurement system

• Subject Area: Condensed Matter Physics
• Term: Funded in 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 558960473

The cryogen-free modular physics measurement system is a universally applicable, fully automated low-temperature and magnetic system for measuring various physical material properties such as fundamental electrical parameters and microwave power absorption in the temperature range of 1.8 to 300 Kelvin, and in high magnetic fields of up to 9 Tesla. A particular advantage of the system lies in its modular design, which allows for future expansion of measurement methods and the application of newly developed measurement techniques. This can often help avoid the need for acquiring additional standalone equipment and achieve optimal resource use. The system is designed as a cryogen-free setup, minimizing ongoing operational costs. The user-friendliness of the measurement system also enables its use in research-driven teaching, thereby providing training for young scientists at the highest apparatus level. The measurement system is required for the experimental work of the newly established group "Cryogenic Quantum Electronics" at the Institute for Electrical Measurement Science and Fundamental Electrical Engineering at the Technische Universität Braunschweig, resulting from a new professorship appointment in July 2024. The system is essential for several ongoing projects and planned research initiatives. It provides measurement methods such as spin-wave spectroscopy and microwave power absorption, which have not yet been available in the Faculty of Electrical Engineering, Information Technology, and Physics. Additionally, the system complements the existing infrastructure of the Laboratory for Emerging Nanometrology (LENA) and is highly relevant for follow-up projects related to the Excellence Cluster Quantum Frontiers. Furthermore, the system will enable a smooth transfer of the applicant's activities from Vienna to Braunschweig and, thanks to its modularity, provide an expandable platform for various collaborations.
