摘要:The cross phase between radial velocity perturbation and poloidal velocity perturbation plays an important role in the radial distribution of Reynolds stress. Recently, a novel theory of cross-phase dynamics predicts that, depending on the strength of the E × B shearing, the...

摘要:A new gas puff imaging (GPI) diagnostic has been developed on the HL-2A tokamak to study two-dimensional plasma edge turbulence in poloidal vs. radial plane. During a discharge, neutral helium or deuterium gas is puffed at the edge of the plasma through a rectangular multi\nobrea...

摘要:Diffraction effects of diagnostic windows and a phase plate are evaluated in sets of phase contrast imaging (PCI) systems on HL-2A tokamak. Results show that wave field of an incident laser with shorter wavelength is less effected by diffraction. The diameter of viewing wind...

摘要:Edge shear flow and its effect on regulating turbulent transport have long been suspected to play an important role in plasmas operating near the Greenwald density limit n G. In this study, equilibrium profiles as well as the turbulent particle flux and Reynolds stress...
