Abstract. ``Studies of the Disruption Prevention by ECRH at Plasma Current
Rise Stage in Limiter Discharges'' Studies of disruption prevention by means
of ECRH in T-10 at the plasma current rise phase in limiter discharges with
circular plasma cross-section were performed. Reliable disruption prevention
by ECRH at HF power
(PHF)min level equal to 20% of ohmic heating
power
POH was demonstrated.
m/n = 2/1 mode MHD-activity
developed before disruption (with characteristic time 
120 ms) can be
considered as disruption precursor and can be used in a feedback system.

Abstract. ``Possibility of an Internal Transport Barrier Producing under
Dominating Electron Transport in the T-10 Tokamak'' The reversed shear
experiments were carried out on T-10 at the HF power up to 1MW. The reversed
shear in the core was produced by on-axis ECCD in direction opposite to the
plasma current. There are no obvious signs of Internal Transport Barriers
formation under condition when high-k turbulence determines the electron
transport.
