The study of two types of T-10 regime-a regime with low impurity confinement (S regime) and a regime with enhanced impurity confinement (B regime) has been continued in deuterium discharges with A, -Aecrit. In the present experiments the transitions from S to B regimes is obtained by the method of gas puff cut-off. Detailed investigations of the profile evolution of T,(r), Ti(r). n,(r) and carbon density 11, showed, that the ?ze(r) profile greatly changes after gas puff cut-off, while T,(r) and TJr) remain practically unchanged at the central zone of the plasma. This indicates the possibility of a relation between the
