Description
The Relic Axion Detector Exploratory Setup (RADES) Collaboration works on the development of new techniques for axion haloscopes. In 2021 we performed a haloscope axion search performed using a custom-made radio-frequency cavity coated with high-temperature superconducting tape, using an 11.7 T dipole magnet at CERN. We will present the results of the search, after analysing a set of 27 h of data at a resonant frequency of around 8.84 GHz, and a width of width of 554 kHz. No signal excess was observed, and an exclusion limit for an axion-like particle in the region corresponding to masses from 36.5676 μeV to 36.5699 μeV, was set. We will also present novel preliminary results of a second data-taking campaign featuring an improved acquisition system, a higher-quality factor cavity and updated data taking protocol performed at CERN in 2024.
