A diagnostic neutral beam injector DINA-KI60 has been developed and produced for upgraded T-15 tokamak (Kurchatov Institute, Moscow). The system will be primarily used for measurement of the ion temperature by chargeexchange recombination spectroscopy (CXRS), for magnetic field measurements via motional Stark effect (MSE) and investigation of plasma turbulence by Beam emission spectroscopy (BES). The ion source provides 60 keV, 6 A hydrogen beam with low angular divergence less than 10 mrad. Ions are extracted from a plasma created by an arc-discharge source with cold cathode and, after accelerating and focusing, are neutralized in a gas target. The extracted beam has about 86% of full energy specie. The grids of ion optical system are spherically curved providing geometric focusing of the beam at a distance 4 m. Diagnostic neutral beam has been successfully tested at Budker Institute of Nuclear Physics at 2 seconds pulse duration with modulation of the beam (duty ratio from 1:1 to 1:3).
