At Fast Neutron Research Facility, the 150 kV-pulses neutron generator is being upgraded to a 280-kV-pulsedHe beam for time-of-flight Rutherford backscattering spectrometry. It involves replacing the existing beam line elements by a multicusp ion source, a 400-kV accelerating tube, 45-double focusing dipole magnet and quadrupole lens. The multicusp ion source is a compact filament-driven of 2.6...

The SPIDER experiment, operated at the Neutral Beam Test Facility of Consorzio RFX, Padua, hosts prototype H-/D- ion source for ITER neutral beam injectors. maximization current extracted from and minimization amount co-extracted electrons are among most relevant targets to accomplish. Cavity Ring-Down Spectroscopy diagnostic measures negative density in close acceleration system, so as have fe...
