The ITER heating neutral beam (HNB) injector, based on negative ions accelerated at 1 MV, will be tested and optimized in the SPIDER source MITICA full injector prototypes, using a set of diagnostics not available HNB. RF source, where H−/D− production is enhanced by cesium evaporation, monitored with thermocouples, electrostatic probes, optical emission spectroscopy, cavity ring down, laser absorption spectroscopy. analyzed cooling water calorimetry, short pulse instrumented calorimeter, visible tomography, neutron imaging. Design diagnostic systems presented.
