APPLICATION OF TWO-DIMENSIONAL MODELLING TO SCRAPE-OFF AND SINGLE-NULL COLLOIDAL DIVERTOR PLASMA OF INTOR
The outer divertor plasma of INTOR and its associated scrape-off plasma have been modelled using a two- dimensional code of transport of plasma energy and particles. It is envisaged that the single-null divertor will operate in a high recycling mode, and in this condition the predicted peak plasma temperatures at the target are T-e approximately equal 30 eV and T-i approximately equal 25 eV. These low values imply that target sputtering will be slight provided that a refractory metal such as tungsten is used. The predicted power loading of the target is about 22 MW/m**2 (in the direction normal to the magnetic surfaces), so that the loading could be reduced to an acceptable level (of about 5MW/m**2) by inclination of the target. The exhaust pumping requirements for helium gas are predicted to be modest.
