Abstract
Soft beta limiting phenomena have been observed in T-10 in ECRH heated plas mas. Neoclassical tearing modes are supposed to be responsible for the beta limitation. MHD onset was observed at high beta (P) values but low beta (N ) values. The critical beta has been found to be almost independent of the collisionality parameter nu (*)(e). Sawtooth stabilization by ECCD does not result in an increase of critical beta. A dependence of the critical beta on the q(r) profile (modified by ECCD) has been observed.
