ITER nuclear fusion experiment operation relies on heating neutral beam injectors based on 1 MeV, 17 MW negative ion deuterium beams, with uniform intensity and low divergence. SPIDER and MITICA experiments in the neutral beam test facility under construction at Consorzio RFX in Padova, will be instrumented with several diagnostics to characterize both negative-ion RF source and accelerated beam to optimize the final injector. Optical emission and laser absorption spectroscopy, with electrostatic probes, measure plasma density and temperature. Beam emission spectroscopy, optical emission tomography, neutron imaging and an instrumented calorimeter measure beam uniformity and divergence.
