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