RADES axion search results with a high-temperature superconducting cavity in an 11.7 T magnet
A bstract We describe the results of a haloscope axion search performed with an 11.7 T dipole magnet at CERN. The search used a custom-made radio-frequency cavity coated with high-temperature superconducting tape. A set of 27 h of data at a resonant frequency of around 8.84 GHz was analysed. In the range of axion mass 36.5676 μ eV to 36.5699 μ eV, corresponding to a width of 554 kHz, no signal excess hinting at an axion-like particle was found. Correspondingly, in this mass range, a limit on the axion to photon coupling-strength was set in the range between g aγ ≳ 6.3 × 10 −13 GeV −1 and g aγ ≳ 1.59 × 10 −13 GeV −1 with a 95% confidence level.
