The COMPASS tokamak (R = 0.56 m, a = 0.23 m, I < 400 kA) is equipped with two identical neutral beam injectors (NBI) manufactured by the Budker Institute of Nuclear Physics, Novosibirsk [1], [2]. Each of them produces the neutral beam with power up to 400 kW at energies of up to 40 keV. This contribution presents determination of beam power losses in the beam duct and of actually injected power into plasma for 40 keV NBI. Then, the global energy confinement time of ohmic and NBI heated discharges is determined and compared with previous results on the COMPASS-D tokamak in the Culham laboratory.
