Taiwan Axion Search Experiment with Haloscope: Designs and Operations

We report on a holoscope axion search experiment near 19.6 mu eV 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 B-0 = 8 T. With a signal receiver that has a system noise temperature T-sys approximately equal to 2.2 K and an experiment time of about one month, the search excludes values of the axion-photon coupling constant g(a gamma gamma) & GSIM; 8.1 x 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 mu eV. We present the experimental setup and procedures to accomplish this search. Published under an exclusive license by AIP Publishing.
