ADMX High Resolution Analysis
ORAL
Abstract
The goal of the Axion Dark Matter Experiment (ADMX) is to detect axions in the galactic halo via their conversion to microwave photons within a cavity. The experiment currently has two analysis channels, one with a frequency resolution of 200Hz referred to as medium res and another with a frequency resolution of 20mHz referred to as HiRes. In the most recent run, run 1c, the data sent to the HiRes channel was in the form of a complex time series. We present our methods and results for the analysis of this data. First, we will discuss the analysis of synthetic axions and pure noise. Next, how this analysis informed our decisions on what qualifies as a possible axion signal and the application thereof to the entire 1c data. Lastly, we will comment on the future work, particularly multi-resolution searches.
