The Cold-Gas Blanket Problem for Turbulent Plasmas
The cold-gas blanket, at least as far as its function as refuelling device is concerned, is a consistent concept only if there exist appropriate steady states of the plasma on a time scale larger than the particle confinement time. The implications of this condition are discussed in general, and the collisional transport model for toroidal geometry is considered as an illustrative example. The importance of a more detailed knowledge about the actual anomalous transport properties for treating the cold-gas blanket problem tealistically, is displayed.
