QCD Axion is a hypothesized particle for solving CP symmetry preserving problem in the strong interaction, and is also considered as a promising candidate for dark matter halo. TASEH (Taiwan Axion Search Experiment with Haloscope) is devoted to searching dark matter axions based on a haloscope setup, consisting of a frequency-tunable microwave cavity detector in a strong magnetic field and a signal receiver. The TASEH experiment targets axion searches in the mass range of 10–25 μeV, roughly corresponding to the frequency band of 2.5–6 GHz. In this presentation, we will describe our first physics search around 19.6 μeV, and also illustrate our latest efforts and the upcoming plans to reach the QCD axion-photon coupling limit in the aimed mass ranges.
