| Abstract: | Neoclassical transport theory for tokamaks in the presence of a radial electrical fieldwith shear is developed using Hamiltonian formalism. Diffusion coefficients are derived in both plateauregime including a large electric field and banana regime including the squeezing factor which can greatlyaffect diffusion at the plasma edge. The scaling on squeezing factor is different from the one given byShaing and Hazeltine. Rotation speeds are calculated in the scrape-off region and they are in good agreement with measurements on TdeV Tokamak. |
