The CAST-CAPP experiment is a joint effort between the CERN Axion Solar Telescope (CAST) collaboration [1] and the Center for Axion and Precision Physics Research (CAPP). The CAPP, located at the Korea Advanced Institute of Science and Technology (Daejeon, South Korea), focuses on two key issues of contemporary physics: the nature of dark matter [DM], and the origin of the matter anti-matter asymmetry of our universe. The nature of DM is investigated through a comprehensive QCD-axion search program including this experiment.
Tunable rectangular cavities will be inserted in the 43 mm twin-bore, 9T, CAST dipole magnet. This will be the first time in which the traditional haloscope technique [2] will be applied in rectangular, rather than cylindrical, geometry. The cavity operational frequency will be in the ~5 to 6 GHz range, corresponding to an axion mass of ~21 to 25 eV. The CAST-CAPP experiment sensitivity could reach into the QCD axion parameter space in this yet unexplored mass region.
