Abstract
Radial electric field is a key physical quantity in determining the structu re of toroidal helical plasmas, owing to the nonlinear dependence of transp ort on the, radial electric field. It has been observed that the potential profiles show various interesting patterns in space and time in the compact helical system (CHS) plasmas. In particular, the phenomenon of electric pu lsation, clearly demonstrates the nature of bifurcation of radial electric field in toroidal helical plasmas.
