Kavli Affiliate: Chao-Lin Kuo | Summary:We present results from the first experimental demonstration of a tunable thin-shell axion haloscope. This novel geometry decouples the overall volume of the cavity-based resonator from its resonant frequency, thereby evading the steep sensitivity degradation at high-frequencies. An aluminum $2.6$ L ($41$ $λ^3$) prototype which tunes from $7.1$ to $8.0$ […]
