Fast neutron sources are of importance not only for basic nuclear physics. The list of other fields of applications includes: dosimetry, neutron detector development, fast neutron oncology, radiation protection shielding materials for accelerator based oncology and Space missions, and the study of single-neutron induced effects in digital and power electronics. This talk introduces fast neutron production using a XTU tandem accelerator at the INFN-LNL, via an 90 MeV beam of 14N6+ onto a lithium target. The commissioning results show clear agreement of the measured spectra with FLUKA simulations. The neutron spectrum is centered around the 8 MeV range with mild tails, and a maximum neutron energy above 50 MeV. This work has been supported by the Clusters of Excellence PRISMA+ and ORIGINS as well as the Collaborative Research Center SFB1258. Moreover, we are grateful for the support from the DFG Research Units 2319 and 5519.
