A Technique to Search for High Mass Dark Matter Axions [CL]


Axions are a well motivated dark matter candidate. Microwave cavity experiments have been shown to be sensitive to axions in the mass range 1 $\mu$eV to 40 $\mu$eV, but face challenges searching for axions with larger masses. We propose a technique using a microwave Fabry-P\'{e}rot resonator and a series of current-carrying wire planes that can be used to search for dark matter axions with masses above 40 $\mu$eV. This technique retains the advantages of the microwave cavity search technique but allows for large volumes and high $Q$s at higher frequencies.
