The axion is a solution to two distinct puzzles in the universe. It was originally proposed by Peccei and Quinn to explain the CP conservation in strong interactions, and in a specific mass range it naturally becomes a dark matter candidate. The CAPP-12T experiment conducted at the Center for Axion and Precision Physics Research (CAPP) searches for axions in the mass range equivalent to 1 – 2...

7. Demonstration of a High-Volume Tunable Haloscope Above 7 GHz

We present results from a first experimental demonstration of a tunable thin-shell axion haloscope, as proposed in [JCAP02(2021)018]. This novel geometry decouples the overall volume of the haloscope from its resonant frequency, thereby evading the steep sensitivity degradation in scaled high-frequency haloscopes. An aluminum 4 L pathfinder (designed for 6.8-8.2 GHz) has been fabricated and...

52. Superfluid Frequency Tuning of Superconducting Cavities for Axion Dark Matter Search

The Center for Axion and Precision Physics Research (CAPP) has introduced a new generation of axion haloscopes by developing high quality factor $(>10^7)$ superconducting cavities even in the high magnetic field, utilizing high-temperature superconducting (HTS) tapes. In order to practically utilize superconducting cavities in axion haloscopes, the tuning mechanism should not compromise the...
