Dynamo effect physics
WebJun 4, 1998 · A series of detailed experiments has been conducted in three laboratory plasma devices to measure the dynamo electric field along the equilibrium field line (the α effect) arising from the correlation between the fluctuating flow velocity and magnetic field. The fluctuating flow velocity is obtained from probe measurement of the fluctuating E×B … WebThe possibility for dynamo effects has not been investigated. In this paper we consider the dynamo process as ob-served in Madison Symmetric Torus MST RFP plasmas.8 In MST, the sawtooth cycle is very distinct and robust, pro-viding a convenient marker for diagnosing magnetic relax-ation effects. Plasmas in other RFP experiments exhibit less
