“…The fast neutrons at MeV scale, where interaction cross sections for hydrogen are significantly lower, are a viable alternative for a source. An established technique of fast neutron resonance radiography, which exploits the resonances in nitrogen, oxygen, and carbon at the ~MeV scale, could prove promising 25 . Other neutron interrogation techniques are also possible.…”

Nuclear disarmament treaties are not sufficient in and of themselves to neutralize the existential threat of the nuclear weapons. Technologies are necessary for verifying the authenticity of the nuclear warheads undergoing dismantlement before counting them toward a treaty partner’s obligation. Here we present a concept that leverages isotope-specific nuclear resonance phenomena to authenticate a warhead’s fissile components by comparing them to a previously authenticated template. All information is encrypted in the physical domain in a manner that amounts to a physical zero-knowledge proof system. Using Monte Carlo simulations, the system is shown to reveal no isotopic or geometric information about the weapon, while readily detecting hoaxing attempts. This nuclear technique can dramatically increase the reach and trustworthiness of future nuclear disarmament treaties.

“…While in the previous examples the material composition is mainly obtained by analysing the neutron induced gamma radiation, work in [2][3][4] is focussed on Fast Neutron Resonance (FNR) imaging for contraband detection. The main difference between the various concepts in FNR is the method to determine the energy of the transmitted neutrons.…”

“…The main difference between the various concepts in FNR is the method to determine the energy of the transmitted neutrons. In [4] a variable, mono energetic neutron beam is produced by accelerated deuterons hitting a deuterium gas target. Another concept applies energy determination by Time-of-Flight (ToF) which is called Pulsed Fast Neutron Transmission Spectroscopy (PFNTS).…”

“…[183] On-resonance transmission images provide contrast to the isotope(s) in the energy ranges analyzed while off-resonance images provide a method of correcting for non-isotope specific neutron scattering and absorption. [184][185][186][187] Using high-energy neutrons, commercial measurements have primarily focused on using resonances in carbon, oxygen, and nitrogen for contraband detection including explosives and narcotics, and in the mining industry for the detection and localization of precious minerals. Using slow neutrons generated from a photonuclear neutron source in a TOF arrangement, prototype experiments have also demonstrated the feasibility of using resonant radiography measurements for assaying the isotopic composition of transuranic elements in spent fuel.…”

Advances in neutron science have gone hand in hand with the development and of particle accelerators from the beginning of both fields of study. Early accelerator systems were developed simply to produce neutrons, allowing scientists to study their properties and how neutrons interact in matter, but people quickly realized that more tangible uses existed too. Today the diversity of applications for industrial accelerator-based neutron sources is high and so to is the actual number of instruments in daily use is high, and they serve important roles in the fields where they're used. This chapter presents a technical introduction to the different ways particle accelerators are used to produce neutrons, an historical overview of the early development of neutron-producing particle accelerators, a description of some current industrial accelerator systems, narratives of the fields where neutron-producing particle accelerators are used today, and comments on future trends in the industrial uses of neutron producing particle accelerators.
