A student-led experiment sets new limits in the search for axions

Phys · · 767 words · By SISSA Medialab

A group of undergraduate students from the University of Hamburg developed a small-scale cavity detector to search for axion dark matter. While they did not detect a signal, their experiment established new experimental limits on axion properties and demonstrated that student-led, resource-limited projects can contribute scientific data.
