Search for Axion dark Matter at UWA

At UWA we have funded axion detection programs for several mass ranges. The research program includes 1) Oscillating Resonant Group AxioN, ORGAN, an experiment to search the mass range 0.06 to 0.21 mev using a 14 Tesla magnet, dilution fridge and novel microwave cavity designs [1]. 2) New experiments with spins, which coupling photonic cavities to magnetic spin wave materials [2] such as YIG and LiFe [3,4]. Such cavities couple, via spin interactions to a particular ALPs governed by the DFSZ model. 3) New low mass broad band and resonant schemes based on lumped LC elements for very low-mass ALPS will developed, which will rival currently proposed magnetometer schemes, with a simpler architecture [5,6]. 4) New experiments with two photons. The new haloscope will excite two highly stabilized photon modes and search for perturbations in these modes caused by galactic halo axions [7,8]. An overview of work done to date and future plans will be presented.
