Vortexlike turbulent structures in hot-ion mode plasmas with several keV are observed in the case with a radially produced weak shear of electric fields Er. However, a strong Er shear formation due to a high ion-confining 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
