Molecular flow gas damping of mechanical motion in confined geometries, and its associated noise, is important in a variety of fields, including precision measurement, gravitational wave detection, and microelectromechanical systems devices. We used two torsion balance instruments to measure the strength and distance-dependence of ``squeeze film'' damping. Measured quality factors derived from free decay of oscillation are consistent with gas particle superdiffusion in L\'evy walks and… Expand
