Abstract

The axion is a compelling dark matter candidate. It is commonly searched for in microwave cavityhaloscope experiments that hope to detect excess photons produced by axion-photon conversion inside a strong magnetic field. The ORGAN Experiment is one such haloscope experiment, which aims to search for high-mass axions (15-50 GHz in photon frequency). This thesis will discuss the initial phase of ORGAN, marking Australia's first dark matter search using this method. This initial phase of ORGAN set the most sensitive limits on axion-photon coupling in the high-mass axion region, excluding the axion-like particle (ALP) cogenesis model.
