Description

We propose a "Light Shining Through Walls"-type experiment to search for axions using high-Q superconducting RF cavities. Our setup uses a gapped toroid to confine a static magnetic field, with production and detection cavities positioned in regions of vanishing external field. We argue that the confining toroid does not significantly screen the axion-induced signal for frequencies of order the inverse toroid size. This setup allows both cavities to be superconducting with quality factors Q ~ 10^10, thus significantly improving the sensitivity of the experiment. Such a search has the potential to probe axion-photon coupling down to g ~ 2 x 10^-11 GeV^-1, comparable to the future ALPS II.
