Vortexlike turbulent structures in hot-ion mode plasmas with several keVare observed in the case with a radially produced weak shear of electric fields Er. However, a strong Er shear formation due to a high ionconfining potential φc production clears up these vortices together with plasma-confinement improvement and disappearance of both drift-wave and turbulencelike Fourier spectral signals. These findings are based on three-time progress in φc in comparison to φc attained 1992–2002. The significant advance of φc is well extended in line with proposed potential-formation physics scalings.
