Taiwan Axion Search Experiment with Haloscope: Designs and operations

Abstract

We report on a holoscope axion search experiment near $19.6\mu \mathrm{eV}$ from the TASEH collaboration. The experiment is carried out via a frequency-tunable cavity detector with a volume $V=0.234\mathrm{liter}$ in a magnetic field $B_0=8\mathrm{T}$. With a signal receiver that has a system noise temperature $T_{\mathrm{sys}}\cong 2.2\mathrm{K}$ and experiment time about 1 month, the search excludes values of the axion-photon coupling constant $g_{\mathrm{a}\gamma \gamma }\gtrsim 8.1\times 10^{-14}{\mathrm{GeV}}^{-1}$, a factor of 11 above the KSVZ model, at the 95\% confidence level in the mass range of $19.4687-19.8436\mu \mathrm{eV}$. We present the experimental setup and procedures to accomplish this search.
