Compact and fully-integrated ZERODUR vacuum system for quantum sensing applications — •David Latorre Bastidas1, Sören Boles-Herresthal1, Nora Bidzinski2, Bojan Hansen2, André Wenzlawski1, Ortwin Hellmig2, Klaus Sengstock2, and Patrick Windpassinger1 — 1Institute of Physics, Johannes Gutenberg University Mainz — 2Institute for Quantum Physics, University of Hamburg
In the context of advancing quantum sensing technologies for real-life applications, we propose a compact, fully integrated, passively pumped ultra-high vacuum chamber based on ZERODUR. This glass-ceramic has a negligible coefficient of thermal expansion (CTE) and ultra-low helium permeability, making it an ideal candidate for vacuum chambers.
This contribution presents the demonstration of a Rubidium-87 magneto-optical trap inside a compact home-built ZERODUR vacuum chamber, using a nanostructured diffraction grating chip (gMOT) and a PCB for the generation of the quadrupole magnetic field. The chamber integrates UV-activated alkali metal dispensers and non-evaporable getters, eliminating the need for electrical feedthroughs. Results are presented on the characterization of the vacuum chamber, where the MOT is used as a pressure sensor, as well as on the MOT performance. This system approach sets the foundation for future compact quantum sensors, offering significant potential for practical, real-world applications.
