Description

I will report about a haloscope experiment in which a hybrid surfaced (copper-NbTi) cavity immersed in a 2 T-magnetic field has been readout by a transmon-based single microwave photon detector (SMPD). The cavity frequency could be varied to probe for different axion masses around 30.5 microelectronvolt by means of a nanopositioner, and I will report about the upper limit that we obtained on the axion-photon coupling in a range of a few hundred kHz.
