  The axion, a consequence of the PQ mechanism, has been considered as the most
elegant solution to the strong-CP problem and a compelling candidate for cold
dark matter. The Center for Axion and Precision Physics Research (CAPP) of the
Institute for Basic Science (IBS) was established on 16 October 2013 with a
main objective to launch state of the art axion experiments in South Korea.
Relying on the haloscope technique, our strategy is to run several experiments
in parallel to explore a wide range of axion masses with sensitivities better
than the QCD axion models. We utilize not only the advanced technologies, such
as high-field large-volume superconducting (SC) magnets, ultra low temperature
dilution refrigerators, and nearly quantum-limited noise amplifiers, but also
some unique features solely developed at the Center, including high-quality SC
resonant cavities surviving high magnetic fields and efficient cavity
geometries to reach high-frequency regions. Our goal is to probe axion dark
matter in the frequency range of 1-10 GHz in the first phase and then
ultimately up to 25 GHz, even in a scenario where axions constitute only 10% of
the local dark matter halo. In this report, the current status and future
prospects of the experiments and R&D activities at IBS/CAPP are described.
