  The Axion Resonant InterAction Detection Experiment (ARIADNE) is a
collaborative effort to search for the QCD axion using techniques based on
nuclear magnetic resonance. In the experiment, axions or axion-like particles
would mediate short-range spin-dependent interactions between a laser-polarized
3He gas and a rotating (unpolarized) tungsten source mass, acting as a tiny,
fictitious "magnetic field". The experiment has the potential to probe deep
within the theoretically interesting regime for the QCD axion in the mass range
of 0.1-10 meV, independently of cosmological assumptions. The experiment relies
on a stable rotary mechanism and superconducting magnetic shielding, required
to screen the 3He sample from ordinary magnetic noise. Progress on testing the
stability of the rotary mechanism is reported, and the design for the
superconducting shielding is discussed.
