Haloscope concept

Haloscopes[1] are experimental devices designed to detect axions, hypothetical particles that are strong candidates for dark matter. These instruments typically use a resonant microwave cavity placed in a strong magnetic field to convert axions into detectable photons via the Primakoff effect.

Haloscopes[2] are most sensitive to axions in a specific mass range and operate by tuning the cavity to resonate at frequencies corresponding to those masses.

The most well-known haloscope experiment to date is ADMX (Axion Dark Matter eXperiment)[3]. Other axion experiments, like IAXO (International AXion Observatory[4] , may incorporate haloscope techniques in its broader axion detection strategy. One of these techniques is RADES (Relic Axion Dark matter Exploratory Setup) which was operated in CAST.
