Students Build Dark Matter Detector and Set New Experimental Limits

University of Hamburg undergraduates designed and ran a simple cavity detector to search for axions.

The experiment found no axion signal, but it established new experimental limits in a narrow search region.

The result shows that small, low-cost setups can still make meaningful contributions to dark matter research.

The work is tied to the MADMAX dark matter effort and was published in JCAP, with support from the Quantum Universe Cluster of Excellence.
