In cavity-based axion search experiments, the quality factor of microwave resonant cavities is an important parameter for improvement of sensitivity to the axion-to-photon coupling. One of the R&D efforts conducted at the Center for Axion and Precision Physics Research (CAPP) of the Institute for Basic Science (IBS) is to develop high-Q cavities with frequency tuning systems. Using a 4K...

The ADMX-HF/Extreme Axion Experiment platform was created to identify and resolve challenges for the microwave cavity experiment in the 2.5–25 GHz range (~ 10–100 μeV), develop new cavity and amplifier technologies, and serve as a data pathfinder in the high mass axion range. The University of California Berkeley is responsible for development of microwave resonators for the experiment; this...

A conventional axion search experiment utilizes microwave resonant cavities, where axions are converted into photons under a strong magnetic field. Optimal cavity dimension is important to enhance signal power from the axion-to-photon coupling, to broaden the scan range, to minimize mode crossings, etc. An extensive study has been performed to optimize the dimensions of cylindrical cavities...

CULTASK (CAPP Ultra Low Temperature Axion Search in Korea) is an experiment to search for the cosmic Axion using resonant cavities, targeting to be sensitive to a large range of microwave photons converted via the Primakoff effect in a very high magnetic field at an ultra low temperature. In order to detect very weak signal of 10^-24 W with a high signal-to-noise ratio, a careful system for...
