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.

Abstract: In one set of embodiments, methods, systems, and apparatus are provided that include presenting, by a computer system, a task flow in a popup component of an application user interface executing in a user interface layer, where the task flow executes in an application layer of the computer system, and also include communicating, by the computer system, a first notification from the application layer to the user interface layer in response to normal completion of the task flow, and updating, e.g., closing, the component in the application user interface based upon the first notification. A second notification may be communicated from the user interface layer to the application layer in response to a user interface event that is associated with the popup component and causes an abnormal termination of the task flow. Presenting may include displaying the task flow in a region component in the popup component.

Abstract: An antenna comprises a square patch element having first and second feed points and lying in a first plane, the first feed point being disposed near a first edge of the square patch element and substantially bisecting the first edge, and the second feed point being disposed near a second edge of the square patch element and substantially bisecting the second edge. The antenna further comprises a feed structure lying in a second plane parallel with the first plane and having a first segment coupled between a signal point and the first feed point, and a second segment coupled between the signal point and the second feed point, where the first and second segments of the feed structure have unequal lengths. The antenna further comprises a ground plane supporting the feed structure and square patch element.
