We report on a holoscope axion search experiment near 19.6  µeV from the Taiwan Axion Search Experiment with Haloscope collaboration. This experiment is carried out via a frequency-tunable cavity detector with a volume V = 0.234 liter in a magnetic field B0 = 8 T. With a signal receiver that has a system noise temperature Tsys ≅ 2.2 K and an experiment time of about one month, the search excludes values of the axion–photon coupling constant ga γγ ≳ 8.1 × 10−14 GeV−1, a factor of 11 above the Kim–Shifman–Vainshtein–Zakharov benchmark model, at the 95% confidence level in the mass range of 19.4687–19.8436  µeV. We present the experimental setup and procedures to accomplish this search.
