    … <p>The inward pinch model for high-Z impurity ions in a toroidally rotating plasma has been improved to take account of trapped particles and the centrifugal force effect. … It is found that the PHZ pinch is large for the barely trapped particles and the pinch velocity increases with the rotation velocity as in the original model.</p> …

    … </i>have proposed two pinch models (i.e., PHZ pinch and Er pinch), which account for the effects of toroidal rotation and the radial electric field, respectively. … Because the assumptions of the Er pinch model are incompatible with the experimental conditions, we study the effect of the PHZ pinch only. …
