Description

The microwave cavity experiment WISPDMX is a haloscope type experiment sensitive to hidden photon and possible light dark matter candidates in a wide mass range below 2 $\mu$eV. The flexible broad-band read-out of WISPDMX provides simultaneous sensitivity to multiple resonant modes as well as to off-resonant frequencies corresponding to particle masses as low as $\sim 10^{-12}$ eV. After completing the construction of a fully tunable WISPDMX setup, the first science run was carried out from 23rd October 2017 to 2nd November 2017 and accumulated a total acquisition time of 61.1 hours with the lowest detectable power of $\sim 10^{-18}$ Watt and sensitivity of $\chi \sim 10^{-14}$ to kinetic mixing of hidden photon dark matter. In this talk, we will present the general developments and the first results from WISPDMX.
