The first plasma experiments on spherical tokamak Globus-M are described. Globus-M is a low aspect ratio tokamak (plasma major radius R = 0.36 m, minor radius a = 0.24 m, R/a = 1.5). The first plasma in Globus-M was achieved in ultra low toroidal magnetic field BT ~ 0.1 T. The inductive plasma breakdown near the vessel centre stack is assisted by RF preionization in the vicinity of electron cyclotron resonance. Two resonance frequencies are used in the experiments: f = 2.4 GHz (Bres = 0.086 T) and f = 9.4 GHz (Bres = 0.34 T). The vacuum vessel conditioning includes bakeout at the temperature of 200 C and glow discharge cleaning in He. Four pairs of poloidal field coils are used for the compensation of central solenoid and vacuum vessel stray magnetic fields and for the monitoring of naturally elongated plasma major radius position. The initial plasma current start-up at a rate up to 10 MA/s is described. The current status of the full-scale plasma experiments is outlined.
