ADMX

The Axion Dark Matter eXperiment (ADMX) High Resolution (HR) Channel searches for flows of non-thermalized halo axions, characterized by their very low velocity dispersion, via the inverse Primakoff Effect. A power spectrum would show such axion flows as a peak with spectral broadening of order Hz or lower. The HR Channel is sensitive to signals of this nature, having a spectral resolution as fine as 40 mHz. In this talk we present a means of analysis for the HR data which will improve upon ADMX's recently published results (resolution of 10.8 Hz) by performing several searches using a range of resolutions while still accounting for signal modulation due to terrestrial motion.
