Abstract: A first system for producing a high flux of neutrons for non-destructive testing includes a dense plasma focus device neutronically coupled to a subcritical or sub-prompt critical fission assembly. The dense plasma focus device is a source of initiating neutrons for the fission assembly, and the fission assembly is configured to multiply a number of the initiating neutrons via inducing fission. A second system for producing a high flux of neutrons includes a gas-target neutron generator neutronically coupled to a subcritical or sub-prompt critical fission assembly. The gas-target neutron generator is a source of initiating neutrons for the fission assembly, and the fission assembly is configured to multiply a number of the initiating neutrons via inducing fission.

Abstract: A system for producing a high flux of neutrons includes a gas-target neutron generator and a fission assembly neutronically coupled to the gas-target neutron generator. The gas-target neutron generator includes an ion source configured to produce an ion beam, an accelerator configured to accelerate the ion beam to produce an accelerated ion beam, a plurality of focus elements configured to focus the accelerated ion beam in an x-direction and a y-direction, and a pumping/gas-target section including a gas target chamber filled with a target gas. The fission assembly is a subcritical or a sub-prompt critical fission assembly. The fission assembly surrounds the gas target chamber. The gas-target neutron generator is a source of initiating neutrons for the fission assembly, and the fission assembly is configured to multiply a number of the initiating neutrons via inducing fission.
