Description
The Taiwan Axion Search Experiment by Haloscope (TASEH) is the first axion experiment in Taiwan. Our detector system included a tunable-frequency cavity immersed in a static magnetic field of 8 Tesla and an amplifier chain with a system noise of ~ 2.2K. From the first data taken in 2021, we excluded the axion-photon coupling $|g_{a𝛾𝛾}| ≳ 8.2 × 10^{-14} GeV^{-1}$, a factor of eleven above the benchmark KSVZ model, in the axion mass range 19.4687 - 19.8436 𝝁eV. This is the first constraints on $g_{a𝛾𝛾}$ in this mass region from a haloscope-type experiment.
