THE EVALUATION OF THE DENSITY LIMITS IN TOKAMAKS
The reconciliation between the ideal mhd ballooning stability and the atomic physics processes, occuring at the edge of the tokamak leads to the limitation on the edge plasma density. For the case of the strong recycling, this density limit is very weak function of the type of the cross field transport, valid for any particular experiment. The consistency of the criteria with the energy balance has been checked up, and the density limit, imposed by the energy losses, owing to recycling has been derived. It seems to be larger than the density limit imposed by the ballooning stability. Finally, it has been quantitatively shown that the relation between the average and the edge density is the strong function of the refuelling source.
