Resistive toroidal stability of internal kink modes in circular and shaped tokamaks
The linear resistive magnetohydrodynamical stability of the n= 1 internal kink mode in tokamaks is studied numerically. The stabilizing influence of small aspect ratio [Holmes et al., Phys. Fluids B 1, 788 (1989)] is confirmed, but it is found that shaping of the cross section influences the internal kink mode significantly. For finite pressure and small resistivity, curvature effects at the q=...
متن کاملGlobal Hybrid Simulations of Energetic Particle Effects on the n=1 Mode in Tokamaks: Internal Kink and Fishbone Instability
Global hybrid simulations of energetic particle effects on the n=1 internal kink mode have been carried out for tokamaks. For the Internationa Thermonuclear Experimental Reactor (ITER) [ITER Physics Basis Editors et al, Nucl. Fusion 3 ̄ 9, 2137 (1999).], it is shown that alpha particle effects are stabilizing for the internal kink mode. However, the elongation of ITER reduces the stabilization e...
متن کاملStudy of Kink Instabilities in Plasma Channels
Heavy-ion beam transport in plasma channels is an option to transport high-current beams which are required in fusion reactor scenarios. The channel provides free electrons that space-charge and current neutralize the ion beams. In addition, the channel creates a large azimuthal magnetic field that prevents the beam ions from leaving the channel. A stable channel is necessary to guarantee good ...

متن کاملModelling and Optimization of Toroidal Continuously Variable Transmission in ECE Driving Cycle
In the present study, the aim is to optimize full and half toroidal continuously variable transmission (CVT) in order to minimize the vehicle fuel consumption (FC) in ECE driving cycle. First, the model of both CVTs’ efficiency is presented. The control strategy of CVTs speed ratio based on minimizing the vehicle FC is introduced, and the algorithm of calculating the vehicle FC is shown. Afterw...
