Superconducting radio frequency (SRF) cavities, initially developed for particle accelerators, have recently (re-)emerged as some of the most promising tools for high precision measurements. In particular, they can be used to search for axion-like particles but also for gravitational waves (GWs) in previously uncharted frequency ranges.
Even before the first measurements of GWs by VIRGO and LIGO, there were already concepts for measuring GWs with SRF cavities in the so called MAGO project.
In addition to its compactness compared to laser interferometers, this concept is motivated by particularly high sensitivity to GWs in the kHz range up to the GHz range. This could lead to the confirmation of predictions from particle physics and cosmology.
The focus of this talk will be on the concept of 'heterodyne GW detection' with SRF cavities and presenting the work we have done so far on an existing prototype. I will also take a look at the future direction of the project.
