The ORGAN Experiment: Current Status, and Future Plans

We present the current status, and future plans of The Oscillating Resonant Group AxioN (ORGAN) Experiment, a high-mass ($\sim60-200~\mu$eV) microwave cavity axion haloscope. ORGAN comprises various phases and sub-phases, having commenced in 2021, and running until 2026. We will discuss each phase, their experimental details, and projected reach. Initial phases rely on well-developed technologies such as traditional tuning-rod resonators, and HEMT amplifiers. Future phases project the use of novel resonant designs based on dielectric structures, and advanced readout techniques based on GHz single photon counters (SPCs). We will discuss the proposed resonant designs, and report on progress in the development of SPCs. It is projected that, with the development of efficient SPCs, within the 12+ Tesla, milli-Kelvin environment available, DFSZ sensitivity is attainable over the entire mass range within the time-scale of the experiment.
