Fusion oriented high temperature plasma experiments often use powerful neutral beams not only for additional plasma heating, but also for purely diagnostic purposes. The diagnostics neutral beams are not supposed to influence the plasma parameters significantly. Unlike the heating beams, they are installed almost perpendicularly to the plasma to allow high radial resolution and are modulated in time to allow subtraction of the passive signal. This report reviews the basic characteristics and first results obtained with the diagnostic beam neutral injector (DNBI) from Budker�s Institute of Nuclear Physics (BINP, Novosibirsk) which was commissioned last year on TCV at the CRPP EPFL.
