A continuously self regenerating high-flux neutron-generator facility

A facility based on a next-generation, high-flux D-D neutron generator (HFNG) is being constructed at UC Berkeley. The current generator, designed around two RF-driven multicusp deuterium ion sources, is capable of producing a neutron output of $>10^{11}$ n/s. A specially designed titanium-coated copper target located between the ion sources accelerates D$^{+}$ ions up to 150 keV, generating 2.45 MeV neutrons through the d(d,$^{3}$He)n fusion reaction. Deuterium in the target is self loaded and regenerating through ion implantation, enabling stable and continuous long-term operation. The proposed science program is focused on pioneering advances in the $^{40}$Ar/$^{39}$Ar dating technique for geochronology, new nuclear data measurements, basic nuclear science research including statistical model studies of radiative-strength functions and level densities, and education. An overview of the facility and its unique capabilities as well as first measurements from the HFNG commissioning will be presented.
