A Search For Non-Virialized Axions in HAYSTAC

One of the most powerful Axion detection methods is the microwave cavity haloscope, such as HAYSTAC (Haloscope At Yale Sensitive To Axion CDM). Axions resonantly convert into microwave photons in a high-Q microwave cavity permeated by a strong magnetic field, and read out by quantum amplifiers. The expected signal is of order a yoctowatt and narrow in frequency to one part in a million. The high-resolution channel searches for non-virialized flows of potentially much narrower linewidth, and is a new addition to HAYSTAC. The analysis is planned to run entirely online during the data taking. This talk will focus on the design of the high resolution channel which will be commissioned for HAYSTAC Phase III.
