Model of H/L transition in tokamak

Creators

Description

New model of the L/H transition in tokamak plasmas is presented. Nonambipolar particle losses determine the consistent radial electric field near the plasma periphery. ''Cusp type catastrophe'' in the space of the radial electric field, particle flux and edge gradients is found. At the transition condition, plasma loss can take multiple values for one profiles of density/temperature near the edge. Critical edge condition is obtained. (author)
