✦ Synopsis

I short revie\. of some features of the edge plasma in limiter tokamaks is given. The limits of thr simple 1-1) SOL model and the relation betw-een the core plasma arc discussed. MARFE phenomcnir and detached plasma are closely connected with the particle and energy balance of the SOL. Their occurrence is bused on the relation of plasma parameters of the edge plasma to those of the core. Important problems of plasma wall interactions are the detection of the irnpurity sources and sinks and the study of the impurity transport and shielding. The non-uniform character of plasma wall interactions and their dependence on the discharge performance still renders difficult any t hc oreticnl forecast of impurity distribution and transport and calls for better diagnost ic.9.
