摘要

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 gaγγ ≳ 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.
