Characterization of the rotational stability of a source mass for the ARIADNE axion experiment

ORAL

Abstract

The Axion Resonant InterAction Detection Experiment (ARIADNE) collaboration will search for the QCD axion using a Nuclear Magnetic Resonance based technique where the axion acts as a mediator of spin-dependent forces between an unpolarized Tungsten source mass and a sample of polarized helium-3 gas. The experiment relies on limiting ordinary magnetic noise as well as a stable rotary system to modulate the axion-signal from the source mass. Updates on the rotating source mass characterization and magnetic background characterization will be discussed.
