The COMPASS tokamak is a compact experimental device (R = 0.56 m, a = 0.2 m) operated in divertor plasma configuration with ITER-like plasma cross-section ([1], [2]). Presently, COMPASS operates with plasma current up to 250 kA and toroidal magnetic field in the range 0.9 – 1.8 T and elongation 1.8. Two neutral beam injectors provide power of 2 x 0.4 MW at the beam energy of 40 keV for additional plasma heating. Recently, an Ohmic as well as NBI assisted H-mode has been successfully achieved on the COMPASS tokamak after application of boronization of the vacuum vessel interior. The L-H transition is followed either by an ELM-free period or ELMs with frequency in the range of 150 – 1 000 Hz.
