Book excerpt: Ripple transport in tokamaks is discussed for the banana drift collisionality regime, which lies below the ripple plateau regime treated earlier. The physical mechanisms that dominate banana drift transport are found to differ from those considered in previous work on this regime, and the resulting transport coefficients can consequently differ by several orders of magnitude.

Book excerpt: The theory of tokamak ripple transport in the banana-drift and ripple-plateau regimes is extended in a number of directions. The theory is valid for small values of the toroidal periodicity number n of the perturbation, as well as for the moderate values (n approx. 10 to 20) previously assumed. It is shown that low-n perturbations can produce much greater transport than the larger-n perturbations usually studied. In addition, the ripple perturbation is allowed arbitrary values of poloidal mode number m and frequency .omega., making it applicable to the transport induced by MHD modes. Bounce averaging is avoided, so the theory includes the contributions to transport from all harmonics of the bounce frequency, providing a continuous description of the transition from the banana drift to the ripple-plateau regime. The implications of the theory for toroidal rotation in tokamaks are considered.

Available in PDF, EPUB and Kindle. Book excerpt: The drift motions of trapped particles in a tokamak field with ripples lead to a new transport process in large tokamaks in addition to the diffusion process due to particles trapped in the ripples. We study this problem by solving the bounce averaged drift kinetic equation with a model collision operator. It is shown that the ''banana drift diffusion'' is proportional to the collision frequency when the poloidal banana drift frequency is smaller than the effective collision frequency. This result is contrary to earlier predictions. In a reactor regime, this loss mechanism is shown to be unimportant.

This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of a finite number of coils to generate the toroidal field of a tokamak introduces a magnetic field asymmetry and is responsible for an additional particle trapping that can affect the plasma confinement. The enhanced transport coefficients associated with the ripple-induced drifts have been calculated. The calculations include both the radial and poloidal variation in the magnitude of the field ripple. It is found that the consideration of poloidal variation significantly reduces the ripple-trapped transport but does not affect the banana-drift diffusion. Results relevant to the ORNL Experimental Power Reactor (EPR) reference design are discussed.
