Angular momentum transport and plasma rotation in response to injected neutral beam torque is a subject both of intrinsic interest and practical consequence (stabilization of MHD instabilities, effect on the H-mode edge pedestal, etc.) in tokamak physics. Faculty and students in the FRC and collaborators have developed the gyroviscous neoclassical theory for angular momentum transfer and applied it to predict rotation and momentum confinement measured in a number of experiments.
