The Axion Dark Matter Experiment (ADMX) 4-cavity array
ORAL
Abstract
The Axion Dark Matter eXperiment (ADMX) is a DOE "Generation 2" direct-detection dark matter project that aims to discover or rule out DFSZ axions. In the pursuit of higher mass axions, cavity diameters must shrink to achieve higher frequencies, leading to a loss in signal-to-noise from the loss in detector volume. ADMX is in the process of producing a 4-cavity array that will allow the DFSZ search to continue up to 2 GHz and beyond. However, the increase in sensitivity from multiple cavities comes at the price of added complexity. Here I will present an overview of the planned ADMX multi-cavity run and its challenges.
