Broad frequency tuning of a NbSn superconducting microwave cavity for dark matter searches
D. Maiello, R. Di Vora, D. Ahn +10
We demonstrate a novel broad-frequency tuning mechanism for superconducting microwave cavities designed for dark matter searches. Using a NbSn-coated cigar-shaped cavity operat…
Magnetic wideband VHF localized field probe using magnon polaritons
Gabriel Soares, Nicolò Crescini, Giovanni Carugno +1
We present here an optimisation and demonstration of a wide band instrument capable of measuring localised and directionally alternated magnetic fields below pT in the very high fr…
Search for post-inflationary QCD axions with a quantum-limited tunable microwave receiver
Giosuè Sardo Infirri, David Alesini, Caterina Braggio +22
A search for cosmological axions has been performed by scanning a frequency region of MHz centered at about GHz, corresponding to an axion mass eV.…
A tunable dielectric resonator for axion searches at 11 GHz
R. Di Vora, A. Gardikiotis, C. Braggio +4
In the context of axion search with haloscopes, tunable cavity resonators with high quality factor and high effective volume at frequencies above about 8 GHz are central for probin…
