The possibility to establish regimes with dense recombining hydrogen plasma in ITER divertor is considered. It is shown that due to the large difference between effective heat transmission coefficients of neutral gas and plasma there is a bifurcation of plasma parameters near the target. Due to this bifurcation a neutral gas layer can occur between the divertor plate and the plasma. The criterion of establishing of this gas layer is found.

Abstract.A kinetic modelling of Id collisional and 2d Vlasov magnetic SOL'S using the W1 and W2 particle codes is presented. Deviation of the distribution function from the equilibrium one is shown! as well as the possibility of kinetic instability in diverted plaSlllaS.
