title = "Helicity, relaxation, and dynamo in a laboratory plasma",
abstract = "The toroidal laboratory plasma known as the reversed field pinch (RFP) is understood through magnetohydrodynamics to undergo an approximately helicity-conserving relaxation to a state which is near a minimum energy “Taylor state.” Experimental observation is consistent with this view. Measurements of the MHD dynamo (the alpha effect), obtained through various experimental measurements or inferences of the fluctuating plasma flow velocity, indicate that the MHD dynamo is active. Additional dynamo effects beyond the standard MHD model, such as pressure-driven or kinetic effects, are also under study experimentally, with some experimental support. However, the standard MHD model has motivated control experiments in which external adjustment of the mean fields leads to reduction in the fluctuation-induced relaxation and dynamo activity.",
