Description
We, the Institute for Basic Science Center for Axion and Precision Physics Research report the first axion dark matter search with toroidal geometry.
A toroidal geometry can provide several advantages, which are a larger volume for a given space and greatly reduced fringe fields which interfere with quantum noise limited superconducting amplifiers.
In this pioneering search, we exclude the axion-photon coupling $g_{a\gamma\gamma}$ down to about $\rm 5 \times 10^{-8}~GeV^{-1}$ over the axion mass range from 24.7 to 29.1 $\mu$eV at the 90% confidence level.
Prospects for axion dark matter searches with larger scale toroidal geometry are also given.
