MODEL OF H - L TRANSITION IN TOKAMAK
New model of L/H transition in tokamak plasmas is presented. Nonambipolar particle losses determine the consistent radial electric field near plasma periphery. Cusp type catastrophe among the radial electric field, particle flux and edge gradients is found. At the transition, plasma loss can take multiple values for one profile of density/temperature near the edge. Critical edge condition for translation is obtained.
