Abstract

A significant particle pinch and reduction of the effective thermal diffusivity are observed after switching the neutral beam direction from coinjection to counterinjection in the JFT-2M tokamak. The particle pinch measured in the counterinjection phase shows good agreement with the prediction of the inward pinch model related to the electric fields.
