densities, but shews a deviation at the low densities. The
equivalent impurity influx calculation in diverted discharges is
not yet possible. The non-steady state of the additionally
heated discharges makes them less accessible to accurate
modelling. However, the trends can be recognised by taking the
observed density rise and the increased power conducted to the
SOL and referring to the experimental scaling of the limiter
discharges. To obtain the lowest possible carbon impurity
concentration in JET, discharges have to be operated at the
highest possible density at any given level of input power.
