Observation of odd toroidal Alfvén eigenmodes.
Experimental evidence is presented for the existence of the theoretically predicted odd toroidicity induced Alfvén eigenmode (TAE) from the simultaneous appearance of odd and even TAEs in a normal shear discharge of the joint European torus. The modes are observed in low central magnetic shear plasmas created by injecting lower hybrid current drive. A fast ion population was created by applying...
متن کاملNonlinear excitations of zonal structures by toroidal Alfvén eigenmodes.
Zonal flows and, more generally, zonal structures are known to play important self-regulatory roles in the dynamics of microscopic drift-wave-type turbulences. Since toroidal Alfvén eigenmode (TAE) plays crucial roles in the Alfvén wave instabilities in burning fusion plasmas, it is, thus, important to understand and assess the possible roles of zonal flow and structures on the nonlinear dynami...
متن کاملElectron trapping in shear Alfvén waves that power the aurora.
Results from 1D Vlasov drift-kinetic plasma simulations reveal how and where auroral electrons are accelerated along Earth's geomagnetic field. In the warm plasma sheet, electrons become trapped in shear Alfvén waves, preventing immediate wave damping. As waves move to regions with larger v(Te)/v(A), their parallel electric field decreases, and the trapped electrons escape their influence. The ...
متن کاملToroidal Rotation Pro�les under the In�uence of Fast-ion Losses Due to Toroidal Field Ripple
Characteristics of toroidal rotation pro�les in tokamak plasmas are studied under the in�uence of fast-ion losses due to a toroidal �eld (TF) ripple by using a one-dimensional multi-�uid transport code, TASK/TX. When a neutral beam (NB) is injected into a plasma, a part of fast ions is lost due to the effect of the TF ripple. The radial current then �ows inward in the bulk plasma to keep quasi-...
متن کاملPlasma Internal Inductance in Presence of Toroidal Field Ripple of Tokamak
In this research we investigated the effects of toroidal field ripple of tokamak on the plasma internal inductance. For this purpose, array of magnetic probes and also a diamagnetic loop with its compensation coil were designed, constructed, and installed on outer surface of the IR-T1 tokamak. Amplitude of the TF ripple is obtained 0.01, and also the effect of the TF ripple on the plasma intern...
