Increasing the negative ions beam neutralization efficiency in NBI system is rather attractive. It is known, that neutralization efficiency of negative ion beam on plasma is higher than on gas. The model of plasma neutralizer for ITER NBI system  -  PNX-U facility is described here. Obtained experimental results give that chosen conception is promising and plasma neutralizer allows essential improvement of NBI system.
